As a Controller at a fast-growing company, you’re in a good position to hire a fractional CFO—not because you need someone to “do finance,” but because you need a senior operator who can **challenge assumptions, elevate decision-making, and help you build the finance function you’ll eventually run with a full-time…
As a Controller at a fast-growing company, you’re in a good position to hire a fractional CFO—not because you need someone to “do finance,” but because you need a senior operator who can challenge assumptions, elevate decision-making, and help you build the finance function you’ll eventually run with a full-time CFO.
A good fractional CFO should complement you, not replace you.
Avoid hiring “a CFO for advice.” That usually creates a vague relationship. Instead, write down 3–5 outcomes you want.
Common reasons a Controller brings in a fractional CFO:
FP&A maturity
Build a driver-based forecast
Create a rolling forecast process
Improve budgeting discipline
Establish KPI reporting
Executive/board support
Improve board decks
Translate financial results into business insights
Help management understand tradeoffs
Scaling finance
Design the finance org structure
Decide what to automate vs. hire
Improve close, reporting, and controls
Strategic decisions
Pricing and margin analysis
Hiring plans
Cash runway planning
M&A readiness
Fundraising preparation
Fractional CFOs are generally focused on forward-looking work—forecasting, capital planning, board reporting, and strategic decisions—rather than the controller responsibilities of close, compliance, and accounting accuracy.
The best candidates have actually lived through your stage of growth.
Ask:
“Tell me about the last company where you built the finance function from X stage to Y stage.”
Strong answers sound like:
Weak answers sound like:
You want scars from operating, not just frameworks.
This is especially important because you already own the accounting engine.
A good fractional CFO should make you better, not undermine you.
Ask:
Listen for:
Good:
“The Controller owns the integrity of the numbers. I help turn those numbers into decisions.” Bad:
“I usually come in and fix finance.”
A mature CFO will say things like:
A strong fractional CFO should be able to discuss:
Depending on your company stage, you may also want experience with fundraising, board reporting, or M&A. Many fractional CFO providers position these as core services for growth companies.
I’d run this:
Questions:
Give them:
Ask:
“What questions would you ask the CEO after reviewing this?” You are testing judgment, not spreadsheet ability.
Ask former CEOs or Controllers:
Fractional CFO pricing varies widely based on stage, time commitment, and whether you hire an individual or a firm. Published examples range from a few thousand dollars per month for lighter advisory work to much higher retainers for embedded leadership.
For a fast-growing company, I’d generally avoid:
A better structure:
First 30 days:
Days 30–90:
Months 3–6:
Sources that often work:
The key filter: “Would I want this person sitting next to me in an executive meeting when the CEO asks, ‘Should we hire 20 people or conserve cash?’”
That’s the person you’re looking for.
As a Controller at a fast-growing company, bringing in a fractional CFO is a massive win—it means you'll have a strategic partner to help scale the big picture while you continue to master the numbers and operations. Since you already own the books, compliance, and close, your ideal fractional CFO needs to complement…
As a Controller at a fast-growing company, bringing in a fractional CFO is a massive win—it means you'll have a strategic partner to help scale the big picture while you continue to master the numbers and operations. Since you already own the books, compliance, and close, your ideal fractional CFO needs to complement your tactical strengths with high-level forward-looking strategy, fundraising/capital structure expertise, and executive leadership.
A structured approach to finding, vetting, and onboarding the right partner includes:
To help narrow down the search, tell me:
Yes. And because **you’re already the Controller**, I would *not* hire a fractional CFO to “help with accounting.” I’d hire someone who complements you by bringing **executive judgment, strategic finance, capital planning, and CEO/board experience**. A good setup is: > **You = owner of financial accuracy, close,…
Yes. And because you’re already the Controller, I would not hire a fractional CFO to “help with accounting.” I’d hire someone who complements you by bringing executive judgment, strategic finance, capital planning, and CEO/board experience.
A good setup is:
You = owner of financial accuracy, close, controls, accounting operations, and reporting infrastructure. Fractional CFO = forward-looking partner who helps management decide what to do with the numbers. That distinction matters. A Controller generally owns the reliability of historical financial information; a CFO should turn that information into forecasts, capital decisions, strategic analysis, and communication with executives/board/investors.
I'd create a one-page CFO mandate before interviewing anyone.
For a fast-growing company, I'd prioritize:
Those are the kinds of forward-looking responsibilities commonly associated with fractional CFO work at growing companies.
Unless you specifically need a hybrid Controller/CFO:
If those are the needs, you're looking for additional Controller/accounting capacity, not a CFO.
This is probably my biggest screening criterion.
I'd strongly prefer someone who has:
A CPA/MBA is nice. Pattern recognition is much more important.
Mercury similarly recommends looking for candidates with actual CFO/VP Finance experience, stage-relevant startup experience, references from founder clients, and relevant fundraising experience rather than simply selecting based on credentials.
Don't make the interview theoretical.
Give your finalists a sanitized version of something you're actually dealing with.
For example:
“We're growing revenue 60% YoY, gross margin is declining, headcount is increasing rapidly, and cash burn is accelerating. The CEO wants to double growth next year. Here's our P&L, cash position, headcount plan and forecast. What would you want to know, and how would you approach the decision?” Then watch what happens.
A mediocre CFO will immediately start talking about EBITDA.
A great one will start asking questions:
You want someone who gets curious before they get prescriptive.
This is particularly important.
You don't want a CFO who treats the Controller as a glorified accounting manager.
Ask:
“What do you expect from your Controller?” A strong answer should sound something like:
“I want the Controller to own the integrity of the numbers and the accounting organization. I want to trust the close, understand the accounting judgments, and have reliable reporting. Then I'll use that information to drive forecasting, capital allocation, and strategic decisions. I'll partner with you rather than recreate your work.” That's a very good sign.
I'd also ask:
“What decisions should I own versus what should you own?” “How would you improve the relationship between Finance and Accounting?” “What would you need from me during your first 30 days?” “What would you change about our finance function after seeing our first three months of reporting?” You're looking for someone who raises your level, rather than someone who wants to take over everything you already do.
I'd use essentially this exact list:
That last one is surprisingly revealing.
You want someone who thinks:
“My job is to build the capability and decision-making discipline inside the company.” Not:
“My job is to maintain a $10K/month consulting engagement.”
I'd make this a paid 90-minute exercise rather than another conversational interview.
Give them:
Ask them to prepare:
“What do you see? What don't you see? What would you change? What would you want to investigate?”
Don't care whether their PowerPoint is beautiful.
Pay attention to:
That exercise will tell you vastly more than another hour of résumé discussion.
Don't just ask for two references they hand-picked.
Ask:
“Can you give me the CEO you worked for at your last CFO role?” And ideally:
“Can I speak with someone who worked for you?” That second reference is particularly valuable.
Ask references:
I would avoid:
“20 hours/month of CFO consulting.” Instead, define outcomes.
For example, the first 90 days could include:
That approach makes the engagement measurable. Current fractional-CFO guidance also emphasizes concrete deliverables such as cash forecasting, financial reporting, KPI development, budgeting and financing readiness rather than vague “financial oversight.”
This is the model I'd aim for:
CEO → owns company strategy and operating decisions
Fractional CFO → challenges strategy financially, develops scenarios, manages capital/forecasting, communicates financial implications
Controller (you) → owns accounting integrity, close, controls, reporting infrastructure and financial data
The CFO should make you more effective, not redundant.
For example:
CEO: “Can we afford to hire 40 people?” You provide the reliable actuals and accounting data.
The CFO says:
“Yes, but here's what happens to cash under three growth scenarios, here's the break-even point, and here's the hiring sequence I'd recommend.” That's the value you're buying.
I'd be cautious if a candidate:
And one particularly important red flag:
They immediately start criticizing your accounting without understanding the business.
A strong CFO should first understand the system and constraints before declaring everything broken.
If I were in your position, I'd rank candidates roughly:
| Factor | Weight |
|---|---|
| Has successfully operated as CFO | 25% |
| Experience at your company's growth stage | 20% |
| Strategic/business judgment | 20% |
| Ability to partner with you as Controller | 15% |
| CEO/board communication | 10% |
| Capital/fundraising experience | 5% |
| Credentials | 5% |
Notice that credentials are only 5%.
I'd take an exceptional former CFO with no MBA over an MBA/CPA who has spent their career doing financial consulting but never actually sat in the CFO chair.
This is the subtle part.
Your CEO probably doesn't need another person who can tell them what happened last month.
You already can.
They need someone who can sit beside them and say:
“Here's what I think is going to happen, here's what could go wrong, here's what I'd do, and here's what it means for our cash, growth and valuation.” That is the fractional CFO I'd hire.
And before you start the search, I'd have a very explicit conversation with your CEO about what they want the CFO to do that you currently cannot or should not be doing. That answer should drive the entire search.
If you'd like, I can also build you a fractional CFO hiring scorecard + interview case study + 90-day scope of work that you could use immediately with candidates.
“Can you give me the CEO you worked for at your last CFO role?” And ideally:
“Can I speak with someone who worked for you?” That second reference is particularly valuable.
Ask references:
I would avoid:
“20 hours/month of CFO consulting.” Instead, define outcomes.
For example, the first 90 days could include:
That approach makes the engagement measurable. Current fractional-CFO guidance also emphasizes concrete deliverables such as cash forecasting, financial reporting, KPI development, budgeting and financing readiness rather than vague “financial oversight.”
This is the model I'd aim for:
CEO → owns company strategy and operating decisions

As a Controller at a fast-growing company, bringing in a fractional CFO is a massive win—if you get the right partner.

As a Controller at a fast-growing company, bringing in a fractional CFO is a massive win—if you get the right partner. You need someone who elevates the strategic conversation, backs you up in front of the executive team and board, and doesn't step on your toes regarding the accounting operations you already have locked down.
Because the fractional CFO market has low barriers to entry (and anyone can slap "CFO" on their LinkedIn profile), your technical vetting as a Controller is critical.
Before you interview anyone, you and leadership need to define where your job ends and theirs begins. A great fractional CFO partnership relies on clear boundaries:
Don’t just look at advisory or accounting backgrounds. Look at their resume with a critical eye:
Since you will be collaborating with them constantly, you need to interview them as much as the CEO does. Look for red flags and green lights:
When you get them on an interview call, use these targeted questions to separate the true operators from the fluff:
If you want to narrow this down further, tell me:
I can help you build a custom scorecard or a tighter list of interview questions tailored to your exact growth stage.
If you’re already the **Controller**, I’d approach this differently from a founder hiring a fractional CFO.

If you’re already the Controller, I’d approach this differently from a founder hiring a fractional CFO. Your goal is not to hire someone to “do finance.” You want a senior operator who complements you: you own accounting, controls, close, and financial integrity; they bring strategic finance, forecasting, capital planning, and executive-level perspective.
Current market guidance broadly draws that same line: the CFO should own forward-looking finance—forecasting, cash, board reporting, strategic analysis, fundraising, and capital decisions—while the Controller owns the accounting foundation.
I'd write the job around 5–7 specific things you want this person to do.
For example:
That gives you a very useful test: if 70% of the candidate's proposed work could be done by a good FP&A manager, you probably don't need a CFO.
I'd prioritize someone who has actually been a CFO/VP Finance inside a company that went through the growth stage you're experiencing, rather than someone whose career has primarily been consulting.
Ideally, they have:
The last point is important. You don't necessarily need someone from your exact industry, but business-model experience is highly valuable. A SaaS CFO and a manufacturing CFO may both be excellent, but their understanding of working capital, revenue recognition, KPIs, and operational drivers can be dramatically different.
This is probably the most important part of your situation.
I'd tell candidates something like:
“I'm the Controller and own accounting, close, controls, and the integrity of our financial reporting. I'm looking for someone who can partner with me and the CEO on FP&A, forecasting, strategy, capital, and executive decision support.” Then ask:
“How would you divide responsibilities between yourself and me?”
A great candidate will immediately understand the distinction.
A bad candidate will either:
You want the former CFO to elevate you, not create a turf war.
Don't rely primarily on conversational interviews.
Give the finalists a sanitized version of your current:
Then give them a scenario.
For example:
“Revenue is growing 35%, gross margin is declining, headcount is growing 45%, and we're going to miss our EBITDA target by $2M. The CEO asks you Monday morning what is happening and what we should do. Walk me through how you'd analyze this.” Watch how they think, not just their answer.
Then ask:
“What information would you want from me as Controller?” That's an excellent test of whether they'll actually know how to work with you.
A live working session is also recommended by current fractional-CFO hiring guidance because it tests the candidate's thinking rather than their sales pitch.
I'd use these almost verbatim:
That last question is particularly revealing. A good fractional CFO shouldn't be trying to perpetuate the engagement indefinitely. They should be thinking about what the company needs next.
I'd actually have finalists spend significant time with you without the CEO present.
You need to determine:
Will this person make my job easier or harder?
The best fractional CFO for you should be someone you can say:
“Here's what happened. Here's what I'm worried about. Here's what I think management is missing. What am I not seeing?” And get an experienced, independent answer.
They should also be willing to tell the CEO:
“I agree with the Controller. Here's why.” That partnership can be enormously valuable.
I would not start with a one-year commitment.
Structure the first 90 days around tangible deliverables. Current fractional-CFO guidance similarly recommends a defined initial sprint rather than immediately locking into a long engagement.
For example:
Days 1–30
Days 31–60
Days 61–90
A competent CFO should be producing decision-useful outputs fairly quickly; industry guidance commonly cites the cash forecast, operating model, KPI dashboard, and finance-process assessment as early deliverables.
There's a meaningful distinction between:
CFO advisor: “Let's meet every other week and I'll give you my perspective.”
and
Fractional CFO: “I own the forecast, cash, board reporting, strategic finance cadence, and I'm accountable for the quality of those outputs.”
If you want someone genuinely embedded in a fast-growing company, I'd favor the second.
Current published market ranges vary substantially by experience and scope, but roughly $6K–$18K/month is a reasonable starting reference point for many fractional engagements, with higher-end executives commanding more.
Don't optimize for the lowest hourly rate. Optimize for how much executive judgment you're actually buying.
I'd use three channels simultaneously:
One current fractional-CFO marketplace, for example, explicitly lists Mid-Atlantic markets including Washington, DC and Philadelphia and provides candidate sourcing.
I'd personally favor warm referrals from CEOs/Controllers you've worked with over a generic marketplace.
I'd be cautious if a candidate:
The ideal profile is probably:
Former CFO/VP Finance of a high-growth company who is analytically strong, operationally minded, comfortable with the CEO/board, and genuinely enjoys partnering with a strong Controller. That's a somewhat different person from the stereotypical “fractional CFO.”
And I'd make the Controller-CFO partnership one of your explicit selection criteria. If you already have a capable Controller, the CFO doesn't need to prove that they can close the books. They need to prove that they can turn your excellent historical financial information into better forward-looking decisions.
If you tell me your company size/revenue, growth rate, industry/business model, whether you're VC/PE-backed, and what you most want the CFO to help with, I can give you a much more specific CFO profile + interview scorecard + 90-day SOW tailored to your situation.
As a Controller at a fast-growing company, bringing in a fractional CFO is a massive win—if you get the right person.

As a Controller at a fast-growing company, bringing in a fractional CFO is a massive win—if you get the right person. You need someone who elevates the strategic conversation with the CEO and board, handles high-level forecasting and capital strategy, but crucially respects the accounting foundation you are building. If they clash with you or treat the books as an afterthought, it will derail your operations.
Here is a step-by-step roadmap to finding, vetting, and hiring a fractional CFO who will be your strongest ally rather than an administrative headache.
To help narrow down the search, tell me:
Hiring a **fractional CFO** as a Controller is a massive power move—it can elevate your strategic footprint, offload heavy forecasting burdens, and position you as the operational right-hand to the executive team.

Hiring a fractional CFO as a Controller is a massive power move—it can elevate your strategic footprint, offload heavy forecasting burdens, and position you as the operational right-hand to the executive team.
Since you are already the Controller, you hold a unique vantage point: you know the messy data, the operational bottlenecks, and where the financial blind spots lie. Here is a step-by-step roadmap to finding, vetting, and onboarding the right fractional CFO.
Step 1: Define the "Why" and the Scope
Before looking at candidates, pinpoint the exact gaps a fractional CFO needs to fill. Since you manage the historical reporting and compliance, what is missing?
Step 2: Establish the Partnership Dynamics
Clarify the reporting lines and working relationship early.
Step 3: Sourcing Candidates
Don't just post on a generic job board. High-end fractional talent is relational and network-driven.
Step 4: Vetting (The Controller’s Technical Screen)
You are uniquely positioned to test their technical chops. In interviews, dig into:
Step 5: Structuring the Engagement
If you'd like, let me know:
I can help you draft a specific interview scorecard or questionnaire tailored to your situation.
No sources cited
Yes. If you’re a Controller at a fast-growing company, I’d hire a **fractional CFO primarily as your strategic thought partner—not as another person to run accounting**. The best person should help you move from *“How do we report what happened?”* toward *“What should management do next?”* That distinction is…
Yes. If you’re a Controller at a fast-growing company, I’d hire a fractional CFO primarily as your strategic thought partner—not as another person to run accounting.
The best person should help you move from “How do we report what happened?” toward “What should management do next?” That distinction is important because the modern CFO role increasingly centers on business value, transformation, and strategic decision-making rather than financial stewardship alone.
Before searching, write down 3–5 problems you want the fractional CFO to help you solve.
For example:
I'd explicitly tell candidates:
"I'm not looking for someone to do my Controller job. I'm looking for someone who can make me better at the CFO-level parts of my job." That will dramatically improve the search.
AICPA's guidance makes essentially the same distinction: if the problem is unreliable accounting/close/reporting, you need controllership; if leadership needs better analysis and decision support, you may need FP&A/CFO-level capability.
This is probably the most important hiring criterion.
I'd favor someone who has actually been:
Be cautious about someone whose experience is primarily:
"I advise companies on best practices." You want someone who can say:
"I had this exact problem at my last company. Here's what we did, here's what went wrong, and here's what I'd do differently." Experience across multiple companies can actually be a major advantage for a fractional CFO because they accumulate exposure to problems that would take years to encounter in a single organization.
Don't make the interview primarily about their résumé.
Give them a sanitized version of an actual problem you're facing.
For example:
"We're growing 40% annually. Revenue is up, but cash conversion has deteriorated. Our forecast is frequently wrong by 15–20%. The CEO wants to hire aggressively, but I don't have confidence in the model. Here's our P&L, cash balance, AR/AP, headcount, and current forecast. What would you do?" Then stop talking.
Watch how they think.
A great fractional CFO will start asking questions such as:
That's much more revealing than asking, "Tell me about your CFO experience."
AICPA similarly recommends interviewing finance executives around real decisions and probing what information they needed, what assumptions they challenged, and how they communicated the recommendation.
This is where I'd be unusually demanding given your role as Controller.
Ask:
"If you were my CFO, what would you expect me to own versus what would you own?"
Then:
"What would you expect me to start doing differently over the next six months?"
And:
"What are the biggest gaps you typically see when Controllers transition toward CFO-level leadership?"
A good answer might involve moving you toward:
AICPA specifically highlights the Controller's evolution from traditional accounting toward business strategy, planning, leadership, and business partnering.
I'd use these almost verbatim:
I'd actually make references part of the selection criteria rather than an administrative step.
Talk to:
Ask:
"When this person disagreed with you, what did they do?" "What did they see that the rest of the management team didn't?" "Did they actually change the business, or were they primarily an excellent finance person?" "What would you have wanted them to do differently?" That last question is particularly useful.
I'd generally start by looking for the individual, even if they happen to operate through a firm.
There are good reasons to use a firm—backup coverage, specialized tax/M&A/FP&A resources, and scalability—but you don't want to discover that you hired a "fractional CFO" and actually get a junior consultant doing most of the work.
Ask:
"Who exactly will I meet with every week?"
"What percentage of the work will you personally do?"
"If I call you with a major issue, what happens?"
"Who attends my CEO/board meetings?"
Some fractional CFO firms specifically target lower-middle-market and fast-growth businesses, so the model itself is well established; the key is making sure you're buying senior judgment rather than hours of outsourced accounting.
For someone in your position, I'd consider:
3-month initial engagement
Then define 3–5 outcomes.
For example:
By day 30
By day 60
By day 90
That gives you a very clean "did this person actually help?" test.
And I'd be especially wary of someone who thinks the CFO's job is simply to produce better reports. Modern CFO expectations are much more oriented toward decision-making, transformation, and business partnership.
I'd use three channels simultaneously:
I'd prioritize a warm referral over a polished fractional-CFO website every time.
If I were writing the search brief, it would be roughly:
Former CFO/VP Finance with 10–20+ years of operating experience, including at least one high-growth company. Has personally built forecasting, KPI reporting, cash management, board reporting, and strategic finance processes. Comfortable working with a Controller rather than replacing one. Strong communicator and coach who can challenge a CEO constructively. Has helped Controllers/VP Finance leaders grow into CFO roles. Available 4–8 hours per month for ongoing advisory plus additional time for specific projects. And I'd make "excellent mentor to a Controller" one of the top three requirements—not an afterthought.
The right person shouldn't make you feel like you've hired someone to do finance for you. You should feel, after six months, that you've become a substantially better finance leader because they were in the room.
If you tell me your company's approximate revenue, growth rate, funding/PE status, industry, and what you most want help with, I can also give you a specific fractional-CFO scorecard, interview script, and compensation/engagement structure tailored to your situation.
As a Controller at a fast-growing company, bringing in a fractional CFO is one of the best moves you can make. It lifts the ceiling on strategic planning, takes the pressure off you for forward-looking forecasting and board-level storytelling, and gives you a powerful partner to scale the finance function. Because you…
As a Controller at a fast-growing company, bringing in a fractional CFO is one of the best moves you can make. It lifts the ceiling on strategic planning, takes the pressure off you for forward-looking forecasting and board-level storytelling, and gives you a powerful partner to scale the finance function.
Because you already own the books, compliance, and day-to-day accounting, your relationship with the fractional CFO needs to be collaborative and complementary.
Step 1: Define the Divide (Your Role vs. Theirs)
Before searching, map out exactly what you need off your plate and where you need backup:
Step 2: Determine Sourcing Channels
You have two main paths to find quality fractional CFO talent:
Step 3: Key Criteria to Screen For
When evaluating candidates, look for these specific markers:
Step 4: High-Yield Interview Questions to Ask
Put candidates on the spot with operational and behavioral questions:
Step 5: Design a Smooth Onboarding & Handshake
Once selected, set them up for a collaborative start:

If you’re a Controller at a fast-growing company, I’d approach this differently than a founder simply looking for “a CFO.” You want someone who complements your controllership function rather than taking it over.
A good fractional CFO should make you better at the forward-looking parts of finance: forecasting, capital allocation, KPIs, strategic analysis, and executive communication. Current guidance similarly emphasizes stage fit, decision support, forecasting, and the ability to work effectively with an existing finance team.
Before searching, write down the 3–5 problems you want this person to solve.
For example:
That last one is particularly important given your role.
I'd explicitly tell candidates:
“I don't need someone to run accounting. I'm looking for someone who can be my strategic finance partner and help me grow from Controller toward CFO-level thinking.” That will immediately separate the right candidates from people who are essentially offering outsourced accounting.
My ideal candidate would have actually been a CFO or VP Finance inside a growing company, rather than having spent their entire career doing fractional CFO consulting.
You want someone who has personally lived through things like:
Experience at a company with a similar growth trajectory and complexity is more valuable than a prestigious résumé alone.
CPA/MBA/CMA credentials can be nice, but I wouldn't make them the primary filter. The CFO skill you're buying is judgment, not another set of accounting credentials.
This is probably the most important thing I'd screen for in your situation.
A bad fractional CFO will think:
“Accounting is tactical. I'll build my own model and tell management what the numbers mean.” A great one thinks:
“The Controller owns the integrity of the numbers. I'll partner with them to turn those numbers into decisions.” Ask candidates:
“Tell me about a Controller you partnered with. What did they own, what did you own, and where did you overlap?”
Then ask:
“If you thought the Controller's forecast or accounting treatment was wrong, how would you handle it?”
You want someone who can challenge you without undermining you.
Also ask:
“What would you expect me, as Controller, to own after you come in?”
Their answer will tell you a lot.
This is better than another hour of résumé discussion.
Give finalists a sanitized version of your company's:
Then give them 60–90 minutes and ask:
“You're joining us as fractional CFO. What do you see? What questions would you ask? What would you change? What would you want to accomplish in your first 90 days?” Don't primarily grade whether their conclusions are “right.”
Watch how they think.
A strong candidate will quickly ask about things like:
And they'll distinguish “I need more information” from pretending they know the answer.
I'd use these almost verbatim:
Then deliberately interrupt them and ask questions.
You want to see whether they can think conversationally, not just deliver a polished presentation.
This matters because some “fractional CFO” firms sell you a senior partner and then hand the actual work to someone much more junior. Availability and the actual staffing model should be explicit before you sign.
Don't just ask:
“Were you happy with them?” Ask the former client:
That last question is surprisingly revealing.
References from CEOs and Controllers/CFOs they've worked alongside are especially useful for you.
I would resist signing a long-term commitment immediately.
A good structure might be:
First 30 days
Days 31–60
Days 61–90
Then evaluate whether they're actually creating leverage.
A recent hiring guide similarly recommends a paid 60–90 day trial rather than immediately making a long commitment.
I'd want something like:
And define deliverables, not just hours.
“20 hours/month” isn't nearly as useful as:
“By the 10th business day, we'll have a management package, updated forecast, variance analysis, cash outlook, and a written summary of the three most important financial issues.” The best fractional CFO engagements are structured around decisions and outcomes, rather than simply selling hours.
I'd prioritize:
You can also use marketplaces and fractional-CFO firms, but I'd use them primarily to generate candidates, not outsource your judgment about who is good. Referrals, firms, marketplaces, and professional associations are all common sourcing channels.
I'd score finalists out of 100:
| Criterion | Weight |
|---|---|
| Experience with your growth stage | 20 |
| Strategic finance judgment | 20 |
| Controller partnership | 15 |
| Forecasting/modeling ability | 10 |
| Executive/CEO communication | 10 |
| Industry/business-model familiarity | 10 |
| Track record/references | 10 |
| Availability/working style | 5 |
I would not give credentials more than ~5% of the score.
The killer combination for you is:
Former operating CFO/VP Finance + experience scaling companies + excellent FP&A/strategic finance skills + genuinely collaborative with Controllers. And one final thought: the best fractional CFO for you may actually be someone who sees your Controller role as a developmental opportunity rather than a reason to replace you. If your longer-term goal is to move toward CFO, explicitly make that part of the hiring criteria. The right person can effectively become your CFO mentor, executive sounding board, and strategic counterpart while you retain ownership of controllership.
If you tell me your industry, approximate revenue, growth rate, funding/ownership structure, and what you most want the CFO to help with, I can give you a much more specific candidate profile + interview scorecard + 90-day scope.
