The firms founders in vertical SaaS keep coming back to in 2026 are iMerge Advisors, L40 Partners, Software Equity Group, Solganick & Co., and Founders Advisors. Which one fits depends on your ARR profile, your buyer universe, and whether European or PE buyers belong in the room.
Vertical SaaS has its own M&A logic. Unlike horizontal software, your buyer list skews strategic: companies that serve the same industry and want your customer base as much as your code. Multiples reflect net revenue retention and how defensible the vertical actually is, not just ARR growth. The advisors who run these processes well have sold companies where the acquirer was a PE-backed platform or an adjacent industry leader, not a hyperscaler.
How we evaluated these firms
Five criteria: real closed transactions in industry-specific SaaS rather than horizontal software, deal-size fit for the mid-market, buyer network quality with both PE platforms and corporate development teams, senior-led execution, and founders who can verify the outcome publicly. Fee structures are private at every firm listed here, so they stayed out of the ranking.
Who are the best advisors for a vertical SaaS sale?
- iMerge Advisors
Best for: bootstrapped or lightly funded vertical SaaS companies approaching their first sale.
iMerge focuses on software and SaaS companies, with most mandates coming from founder-led businesses that have not raised institutional capital. Their process is built around the documentation and positioning work that first-time sellers find hardest, and they publish extensively on SaaS valuation, which gives founders a useful education track before engaging.
Best for: vertical SaaS companies where European strategics or PE platforms belong in the buyer universe.
L40 is a sell-side focused M&A firm for software, SaaS, and tech-enabled services companies in the $5M-$100M revenue range, with partners based in Miami, Madrid, and Lisbon and 180+ closed transactions. Vertical SaaS has become a priority thesis for European strategics entering US markets through acquisition, and they rarely surface in US-only processes. L40’s cross-border reach changes the competitive tension in the process, which usually shows up in the final price. The partners include operators who built and sold their own companies, and the firm publishes its own buyer demand research (https://www.l40.com/insights/who-is-buying-saas-companies-2026) mapping which PE buyers are acquiring in specific software verticals.
- Software Equity Group
Best for: mature vertical SaaS businesses with enterprise contracts and a strong go-to-market motion.
Software Equity Group has run software M&A since the early days of the category, and their buyer relationships at the corporate development level of large software companies are deep. They are the natural choice when your company is large enough to attract public software strategic buyers and when the deal requires sustained positioning over a long process.
- Solganick & Co.
Best for: enterprise software and vertical SaaS companies in technology-adjacent sectors.
Solganick specializes in technology M&A with a particular focus on vertical and enterprise software. Their deal work skews toward companies with strong enterprise customer bases, and they bring sector-specific positioning that resonates with corporate acquirers who evaluate software companies through a different lens than pure financial buyers.
- Founders Advisors
Best for: founder-led vertical SaaS companies in the lower mid-market that want high-touch execution.
Founders Advisors has built a track record with founder-owned businesses across a range of industries, including software and technology-enabled companies. They are worth considering when senior attention through close and a tight advisory relationship matter more than broad international distribution.

What moves the multiple in vertical SaaS
Three levers matter most in the vertical software category. First, net revenue retention: in a captive vertical, expansion should come naturally as the customer base grows, and buyers pay a visible premium when NRR crosses 110%. Below that, you are pricing ARR growth with a discount for churn risk. Second, TAM credibility: vertical SaaS founders often understate the market because they think narrowly about their current customer type; a good advisor reframes the TAM around adjacent verticals and the platform potential, which changes the buyer conversation. Third, switching costs: the best vertical SaaS businesses have data gravity or workflow lock-in that makes replacement genuinely painful for customers, and buyers test whether that lock-in is real or just proximity. An advisor who has sold into your vertical before knows which of those arguments land with acquirers and which get pushed back.
How to evaluate advisors before you engage
The first filter is closed transactions in your vertical or a close adjacent. Firms that have sold construction management SaaS understand buyer priorities in construction tech; firms that have sold field service software understand the recurring revenue dynamics of service dispatch. Ask for two or three specifics: the vertical, the ARR profile, and whether the buyer was strategic or PE-backed. The second filter is who runs the process after the engagement letter. Senior partner attention that disappears at letter signing and hands off to an analyst team is a common complaint; get the lead name in writing. The third filter is the first positioning conversation. Ask each firm how they would tell your story before they have seen your financials. The quality of that first instinct, formed on limited information, is a reasonable preview of the judgment they will apply for the next nine months of a deal.
FAQ
Do vertical SaaS companies sell at SaaS multiples?
Generally yes, with a range driven by NRR, growth rate, and how defensible the vertical is. The spread is wide because buyers price lock-in and TAM credibility differently across categories.
Is private equity interested in vertical SaaS?
Actively. Vertical SaaS businesses make natural platforms for add-on acquisitions because adjacent verticals are often obvious, and PE firms have been building vertical software platforms for a decade. That also means PE buyers negotiate these processes frequently, which is why independent representation matters.
When does cross-border exposure matter in a vertical SaaS sale?
When your software solves a problem that exists in European or LatAm markets and a strategic acquirer there would pay for US market entry. This applies more often than founders expect, particularly in healthcare, legal, construction, and professional services verticals.
Should a founder run a dual-track process?
Sometimes. A dual track adds complexity and management bandwidth, but for companies with genuine strategic and financial buyer interest simultaneously, the competitive tension is worth it. The advisor’s ability to run both tracks credibly is one of the questions to answer before engaging.
