Yes. Treat the investor as a counterparty you are diligencing, not just as a source of cash. An angel can be perfectly legitimate and still be a terrible investor for your company—e.g., controlling, unreliable, overly involved, or prone to blocking future financing.
Don't just ask for the references the investor gives you. Find founders independently through LinkedIn, your network, accelerators, lawyers, or other investors.
Ask:
The last question is particularly revealing. 2. Check their regulatory and legal history
If they're acting as an investment professional, search the SEC's Investment Adviser Public Disclosure (IAPD) database and FINRA BrokerCheck. These can reveal registration status, employment history, complaints, regulatory actions, and other disclosures.
Keep in mind that a normal angel investing their own money may not appear in these databases; absence from them isn't inherently suspicious. The SEC describes angel investors as generally investing their own money directly into emerging businesses. SEC 3. Search beyond regulatory databases
Search the investor's:
Also check court records and reputable news sources where appropriate. Don't treat a single negative online comment as proof of misconduct—look for patterns and corroboration. 4. Investigate their actual investing history
Don't rely on their pitch deck or LinkedIn profile.
For each claimed investment, verify:
You're looking for consistency between what they claim and what independent evidence shows. 5. Understand exactly what they want in return
This is often more important than their reputation.
Have your lawyer review:
A friendly investor offering $500k can be much more expensive than a difficult investor offering $1m if the terms give them disproportionate control. 6. Ask how they behave when founders disagree with them
This is one of the best interview questions:
"Tell me about a company you've invested in where the founder made a major decision you disagreed with. What happened?" Listen for whether they say something like "I explained my position and ultimately supported the founder" versus "I made sure they understood they couldn't do that."
Find out whether they invest in competitors, have relationships with your customers/suppliers, or have incentives that could conflict with yours.
If they are investing through a fund or SPV, understand who actually controls the investment vehicle and who has rights against your company. Recent SEC scrutiny of private-company SPVs is a good reminder not to take an investor's claimed structure or access at face value. The Wall Street Journal 8. Get your own lawyer involved before signing
Ideally, use a startup lawyer who has represented founders—not the investor's lawyer. Ask them specifically:
"Is there anything unusual about this investor's proposed terms or rights that could create problems in our next financing?"
The SEC itself recommends independently researching people involved in investments rather than relying solely on information or references supplied by the other party.
Before accepting the money, ask two founders they invested in who are doing well and two whose companies didn't work out.
The failed companies are often more informative. Anyone can be a great investor when a company is succeeding; you want to know what happens when the investment is going badly.
If you give me the angel investor's name (and fund/company, if applicable), I can also do a public-record/news/reputation check and give you a structured green flags / yellow flags / red flags assessment.
Just as investors run background checks on founders, you should do "reverse due diligence" on an angel investor before taking their cash. Money comes with strings attached, and a toxic or unhelpful angel can make your life miserable—especially during hard…
Just as investors run background checks on founders, you should do "reverse due diligence" on an angel investor before taking their cash. Money comes with strings attached, and a toxic or unhelpful angel can make your life miserable—especially during hard times.
Evaluating an angel investor's reputation involves a structured, practical approach:
If you'd like, let me know:
I can help you put together a short list of specific questions to ask their references.
Taking money from an angel investor is a multi-year marriage—they will be on your cap table, potentially sitting on your board or holding information rights, and impossible to get rid of if things go south. Running due diligence on them is just as important as them running it on…
Taking money from an angel investor is a multi-year marriage—they will be on your cap table, potentially sitting on your board or holding information rights, and impossible to get rid of if things go south. Running due diligence on them is just as important as them running it on you.
A step-by-step framework to backchannel and check an angel investor's reputation before you sign includes the following actions:
If you'd like, let me know:
I can share a quick list of deal-breaking red flags to watch out for during these conversations.
Before accepting money from an angel investor, treat the investor almost like you would a cofounder: **you’re not just taking capital—you’re potentially adding a long-term relationship to your company’s cap table.** Here’s a practical due-diligence process. ## 1. Talk to founders they’ve backed
Before accepting money from an angel investor, treat the investor almost like you would a cofounder: you’re not just taking capital—you’re potentially adding a long-term relationship to your company’s cap table.
Here’s a practical due-diligence process.
This is probably the highest-value check.
Ask the investor for 3–5 references, including:
Ask the founders privately:
The last question is especially revealing.
Also try to find founders the investor didn't nominate as references. LinkedIn, accelerator networks, lawyers, and other founders can help you identify them.
If the person has worked as a broker, investment adviser, or financial professional, check brokercheck.finra.org and the SEC's adviserinfo.sec.gov.
BrokerCheck can show registration history, employment history, customer disputes, regulatory actions, arbitrations and certain other disclosures.
The SEC recommends checking these databases and state securities regulators rather than relying solely on what an investment professional tells you.
Important: an ordinary angel investor may not appear in these databases. That's not automatically a red flag. It simply means you need to rely more heavily on other forms of diligence.
Search combinations of their:
Look at both positive and negative information. One angry former founder doesn't necessarily establish misconduct; you're looking for patterns, corroboration, and unexplained inconsistencies.
FINRA itself notes that BrokerCheck doesn't contain every type of litigation or criminal information, so independent research can be useful.
Ask for a portfolio list and independently verify it.
For each investment, find out:
Don't be overly impressed by a portfolio containing famous startups. A famous portfolio doesn't necessarily mean they're a good investor for you.
You care about how they behave with companies like yours.
A "great" investor offering $500k can be much worse than an ordinary investor offering $500k on clean terms.
Have a startup attorney review provisions concerning:
If an investor says, "This is standard; don't bother having your lawyer review it," that's a significant warning sign.
Their behavior before they invest is useful evidence about what they'll be like afterward.
The SEC specifically warns about impersonation scams and recommends independently verifying an investment professional's identity through official regulatory resources rather than trusting links or information supplied by the person.
If you're raising from multiple investors, ask your lead VC, accelerator, startup lawyer, or experienced founder:
"Have you worked with or seen this investor before? Anything I should know about them?" Investors often have a surprisingly good informal network for this.
A particularly useful question is:
"If this investor were on my cap table, what would you worry about?"
This is the test I'd use:
Imagine your startup misses its targets badly two years from now. What happens?
Ask yourself:
You're evaluating behavior under stress, not just their behavior while they're trying to win the deal.
| Area | Question | Score |
|---|---|---|
| Founder references | Would founders take their money again? | /5 |
| Integrity | Any unexplained legal/regulatory concerns? | /5 |
| Track record | Evidence of genuine investing experience? | /5 |
| Value-add | Can they materially help this company? | /5 |
| Behavior | Respectful, transparent, non-controlling? | /5 |
| Terms | Clean, market-standard documents? | /5 |
| Downside behavior | Would you trust them when things go badly? | /5 |
I would not accept an investor solely because they have a good reputation online. The strongest signal is usually a combination of private founder references + clean documentation + consistent behavior + independent verification.
If you give me the investor's name and the startup/portfolio context, I can also show you exactly how I'd research that particular angel—including what public records, portfolio companies, founder commentary, and red flags I'd look for.

Yes. Treat an angel investor like you would treat a key employee or business partner: **you’re not just evaluating whether they can provide cash—you’re evaluating what happens after they own part of your company.** ## A practical investor due-diligence process ### 1. Talk to founders they have actually invested in
Yes. Treat an angel investor like you would treat a key employee or business partner: you’re not just evaluating whether they can provide cash—you’re evaluating what happens after they own part of your company.
Ask the investor for 5–10 founder references, including:
Ask those founders privately:
That last question is often the most revealing.
Search the investor's full legal name, investment firm, previous companies, and portfolio companies. Don't rely solely on their LinkedIn or website.
Look for:
If they are a financial professional, check the SEC's Investment Adviser Public Disclosure (IAPD) and FINRA's BrokerCheck. These can show registration history, employment, qualifications, customer disputes, and certain regulatory/disciplinary disclosures.
Importantly, not appearing in IAPD/BrokerCheck isn't automatically a red flag for an angel. Many angels invest their own money and aren't acting as registered investment professionals.
A famous investor can still be a terrible investor for your company.
Pay particular attention to:
Have a startup attorney review the documents before you sign, particularly if the terms aren't standard.
You want to know whether the person actually has the resources they claim.
Ask:
"Can you provide evidence that you have the funds available to close this round?" Also clarify whether the investment is:
If they say they're investing through a fund, understand who controls the fund and whether the person you're negotiating with actually has authority to make the investment.
This is increasingly important.
Don't verify someone using contact information they supplied in an unsolicited message. Independently find the investor's legitimate website/contact information and verify their identity.
The SEC specifically warns that imposters can misuse the names of legitimate investment professionals and even point people toward seemingly legitimate resources.
I'd ask:
"What would cause you to lose confidence in me as CEO?" "What decisions would you expect to have a say in?" "Under what circumstances would you want to replace a founder?" "Tell me about an investment that went badly and how you handled it." "Can you introduce me to a founder whose company failed while you were an investor?" "Have you ever had a serious disagreement with a founder? What happened?" Their reaction can be more informative than the answer.
A good investor shouldn't be offended that you're doing diligence. They're asking you to trust them with ownership of your company, so due diligence is completely reasonable.
🟢 Green flags
🟡 Yellow flags
🔴 Red flags
Don't evaluate the investor separately from the term sheet. Evaluate the combination.
A wonderful angel with terrible terms can be a bad deal. A relatively unknown angel with reasonable terms, excellent founder references, useful expertise, and professional behavior can be a much better partner.
If you give me the investor's name, LinkedIn/website, and the basic terms they're offering (investment amount, valuation/cap, board rights, etc.), I can also walk you through a structured reputation and deal-risk check.

Checking an angel investor’s reputation—often called "reverse due diligence"—is one of the most critical steps a founder can take. An investor is on your cap table for years, through highs and lows, so you need to know how they behave when things get tough.
A practical, step-by-step framework helps you vet an angel investor before signing a term sheet or cashing a check:

Yes. Treat the investor like a key hire or business partner—not just a source of cash. **You’re evaluating both whether they’re legitimate and whether you actually want them on your cap table.** ## 1. Verify who they are Start with their full legal name, investment entity, employer history, and claimed portfolio.
Yes. Treat the investor like a key hire or business partner—not just a source of cash. You’re evaluating both whether they’re legitimate and whether you actually want them on your cap table.
Start with their full legal name, investment entity, employer history, and claimed portfolio.
Important: An angel investor doesn't necessarily need to be registered simply because they're investing their own money. So a clean BrokerCheck/IAPD result is useful, but absence from those databases isn't itself a red flag.
This is probably the most valuable part.
Ask the investor for 5–7 founder references, including at least one company that struggled or failed. Ideally, independently find some founders yourself rather than relying entirely on their hand-picked references.
Ask references:
The last question is especially useful.
Backchannel references are often more revealing than the references the investor provides.
A famous investor with impressive exits can still be a terrible investor for your company.
Look for evidence of:
Also distinguish the individual angel from the firm or syndicate. The person who will actually interact with you matters more than the brand on their business card.
Ask where the investment is coming from and make sure the entity sending the money matches the entity in your documents.
Be particularly cautious if they:
An angel-investor due-diligence guide specifically flags upfront fees, pressure tactics, evasiveness, and unverifiable claims as warning signs.
Don't evaluate the investor separately from the deal.
A problematic investor can become substantially more problematic if you give them:
Have startup counsel review the actual term sheet and definitive documents, not just the headline valuation.
Tell them you're doing reference checks and legal diligence.
A good response is essentially: “Of course—what else would you like to know?”
If they become angry, pressure you to skip references, discourage you from using a lawyer, or threaten to withdraw because you're asking reasonable questions, that's itself valuable information. Reference-checking is considered normal diligence among experienced investors.
I'd want these five boxes checked:
And one particularly useful question to ask yourself:
“If this company struggles badly in 18 months, would I still want this person sitting at my board table?” If the answer is no, don't let the attractiveness of the check obscure the cost of taking it.
I'd want these five boxes checked:

Yes. Treat the investor like a potential long-term business partner, not just a source of cash. An angel can affect your board, future fundraising, hiring, strategy, and reputation.
Here’s a practical way to vet them:
Search their full name, investment entity, and company history independently.
Look for:
For U.S. investment professionals, the SEC's Investment Adviser Public Disclosure (IAPD) and FINRA's BrokerCheck can show registration, employment history and certain disciplinary information.
Don't settle for "I've invested in dozens of startups."
Ask for:
Then independently verify the companies and investment claims.
A failed investment isn't necessarily a red flag. What matters is whether the investor has a credible track record and behaves well when things go badly.
This is probably the highest-value step.
Ask the investor for 2–3 founders you can contact. But don't stop there: find founders from their portfolio yourself and contact them through mutual connections.
Ask:
That last question can be particularly revealing.
Recent founder guidance similarly recommends combining investor-provided references with independently sourced references, including at least one company where the relationship or outcome wasn't particularly successful.
This is arguably more important than their investment track record.
Ask yourself:
"What happens when I say no to this person?"
A good angel can disagree strongly while still respecting your authority as founder.
Be cautious if they:
A seemingly attractive valuation can conceal expensive control provisions.
Pay particular attention to:
Have a startup attorney review this before signing.
Search combinations such as:
"Investor Name" lawsuit
"Investor Name" founder
"Investor Name" portfolio
"Investor Name" dispute
"Investor Name" startup
"Investor Name" "would invest again"
Also search former portfolio companies, not just current ones. A surprisingly useful question is:
"Who previously took this investor's money and later stopped working with them?"
Be particularly careful if the investor:
An investor doing legitimate diligence on you is normal; you doing diligence on them is equally normal. Investor-due-diligence guidance specifically flags upfront fees, pressure tactics, unverifiable histories, and reluctance to provide references as warning signs.
Before taking the money, score them 1–5 on:
| Category | Score |
|---|---|
| Reputation with founders | /5 |
| Integrity/transparency | /5 |
| Relevant expertise | /5 |
| Helpfulness beyond money | /5 |
| Behavior during disagreement | /5 |
| Terms/control they're requesting | /5 |
| Ability to support future rounds | /5 |
| Quality of references | /5 |
I'd be much more concerned about a 2/5 on integrity or behavior than a 2/5 on expertise. You can survive having an investor who isn't particularly helpful. A hostile investor with control rights can be much harder to escape.
The single best test: talk to a founder whose company struggled while this investor was involved. Ask what the investor did when things stopped going according to plan. That's where reputation becomes reality.
