If your SaaS does $5M of revenue and is already profitable, you’re in a very attractive part of the lower-middle-market software M&A universe. I would not limit the buyer universe to traditional search funds. The best potential buyers are actually a mix of permanent-capital software acquirers, micro-PE, SaaS aggregators, and well-capitalized searchers.
The key variable is EBITDA/SDE, growth, ARR quality, and customer concentration. At $5M revenue, a company with $1.5M EBITDA is a very different asset from one with $300K EBITDA.
My shortlist
| Buyer | Best fit | Why I'd approach them |
|---|
| tiny.com | Profitable SaaS/software, roughly $5M+ enterprise value | Permanent capital, founder-friendly, can buy outright, explicitly says it does deals from $5M–$300M |
| banyansoftware.com | Vertical/industry SaaS | Probably one of the strongest fits if you're a niche-market software leader |
| sureswiftcapital.com | B2B SaaS, $1M–$5M+ revenue | Specifically targets profitable/breakeven SaaS and is active in this size range |
| saas.group | Product-led/general-purpose SaaS | Explicitly targets $2M–$10M ARR, particularly profitable businesses |
| csisoftware.com | Vertical-market software | One of the most sophisticated permanent owners of small software businesses |
| valsoftcorp.com | Vertical B2B software | Excellent candidate for niche, sticky, recurring-revenue software |
| everfield.com | European/vertical SaaS | Permanent software platform with an acquisition-oriented model |
| Search-fund buyers | Owner-operated, profitable SaaS | Particularly interesting if EBITDA is ~$1M–$2M+ and the buyer wants to become the CEO |
1. Tiny — probably my first call
Tiny is unusually well matched to what you've described.
Tiny says it acquires profitable businesses and can do transactions from $5M to $300M. It specifically says founders can sell all or part of the business, stay or leave, and that it uses permanent capital rather than a conventional PE fund with a forced exit timeline.
Its stated criteria—profitability, healthy margins, defensibility, a team worth keeping, and being at least three years old—sound very compatible with a mature profitable SaaS company.
I'd put Tiny near the top of your list if:
- you want a clean/full exit;
- you care about the product surviving intact;
- you don't want a 3–5 year PE resale;
- you're willing to accept that a strategic/competitive auction could potentially produce a higher headline price.
2. Banyan Software — especially if you're vertical SaaS
Banyan Software is another exceptionally good target.
Banyan says it generally looks for >$2M revenue, profitability/free cash flow, high recurring revenue, strong retention, defensible niche positions, and committed teams. It explicitly describes itself as a permanent owner rather than a traditional PE fund.
So if your SaaS is something like:
- healthcare software
- government software
- education
- transportation/logistics
- financial-services software
- specialized business workflow
…I'd move Banyan toward the very top of the list.
3. SureSwift — particularly strong fit for smaller SaaS
SureSwift Capital is worth contacting directly.
Its published acquisition profile is almost comically close to your description: B2B software, SaaS, $1M–$5M TTM revenue, 10–30% growth, bootstrapped/lightly capitalized, ideally EBITDA-positive or approaching profitability, with low churn and strong retention.
And SureSwift says that its 2026 acquisition activity is concentrated heavily in the $1M–$30M ARR segment.
If your $5M revenue is mostly recurring revenue, I'd absolutely include them in the first wave.
4. saas.group
saas.group is another strong fit, especially for a horizontal/product-led SaaS.
They explicitly target SaaS businesses with approximately $2M–$10M ARR, with a preference for profitable businesses, product-led/self-service models, relatively lean operations, and customers in North America/Western Europe.
So if you're doing $5M revenue but aren't particularly verticalized, I'd probably put saas.group ahead of many traditional PE funds.
5. Constellation Software / its operating groups
Constellation Software is the elephant in the room.
Its model is almost purpose-built for acquiring boring, profitable, niche software companies and holding them for a very long time. Its operating groups include companies such as Volaris, Harris, Jonas, Vela, Perseus and Topicus.
The important caveat: don't approach Constellation as though you're pitching a conventional PE fund. The relevant question is whether your software fits one of its vertical-market operating groups. If it does, it can be an extremely credible buyer.
I'd especially consider it if you have:
- 90%+ recurring revenue;
- high retention;
- a defensible niche;
- low customer concentration;
- relatively low capex;
- stable rather than hypergrowth economics.
6. Valsoft / Everfield
Valsoft and Everfield belong on the broader strategic buyer list.
They're more interesting if your product is vertical B2B software rather than a consumer SaaS or trendy horizontal application.
I would treat these alongside Constellation and Banyan rather than thinking of them as conventional "micro-PE."
What about search funds?
This is where I'd be selective.
A search fund is generally an entrepreneur raising capital to buy one company and personally operate it. That's quite different from selling to Tiny or Banyan.
The latest Stanford search-fund research is encouraging: software is one of the major target industries, and the median purchase price for search-fund acquisitions in 2024–25 was about $16M.
That means a $5M-revenue SaaS company is absolutely within the ecosystem.
But there's a big difference between:
"I want a professional investor to buy my company and operate it as part of a portfolio"
and:
"I want a 35-year-old former McKinsey/Stanford MBA to buy my company and become CEO."
The latter can work very well, but you're likely to see more:
- seller financing;
- rollover equity;
- earn-outs;
- SBA/senior debt;
- transition requirements;
- negotiation around your continued involvement.
On the other hand, a great searcher can sometimes be more emotionally and operationally invested in preserving the business than traditional PE.
I'd therefore run a parallel search-fund process, rather than relying on it as your primary buyer channel.
Who I'd contact first
Assuming you're in the U.S. and this is a healthy, founder-owned SaaS, my initial buyer list would be:
- Tiny
- Banyan Software — move to #1 if vertical SaaS
- SureSwift
- saas.group
- Constellation / relevant operating group
- Valsoft
- Everfield
- 10–20 carefully selected software-focused searchers
- A handful of independent sponsors / micro-PE funds
- Strategic competitors
I would not start by blasting 100 PE firms. At your size, buyer fit matters enormously.
The really important question: what's your EBITDA?
If you give me these six numbers:
- ARR / recurring revenue
- TTM revenue
- TTM EBITDA
- YoY growth
- net revenue retention
- customer concentration (e.g. largest customer = 8%)
…I can give you a much more useful answer: a ranked list of ~20 specific buyers/search funds, likely valuation range, who is most likely to pay the highest price, and who is most likely to give you a clean 100% cash exit.
For example, $5M revenue / $2M EBITDA / 20% growth / 95% recurring revenue should be marketed very differently from $5M revenue / $750K EBITDA / 5% growth.
