A profitable mid-market SaaS company is one of the easiest assets to sell and one of the easiest to undersell. Buyers (private equity, PE-backed platforms and strategics) know the metrics cold, so the advisor's job is less about finding a buyer and more about running a process tight enough that the buyer pays for the retention, the margin and the growth rather than discounting all three.
This list ranks the advisors we would put in front of a founder-owned SaaS business with no outside capital, real EBITDA and $5M to $100M in ARR. It leans toward firms whose whole practice is software. Deal-level comparables sit in the SaaS cut of the ProCloser deal index.

The 10 best M&A advisors for profitable mid-market SaaS companies
1 Software Equity Group
Best for: profitable, founder-owned B2B SaaS companies that want a software-only advisor with deep published deal data.
Software Equity Group (SEG) advises B2B software, SaaS and AI founders on the sell side and nothing else. Its site reports 175+ software deals closed, more than 10,000 active buyer relationships, an 87% buyer response rate and 30+ years of practice, along with a set of proprietary tools (the SEG SaaS Index, a SaaS M&A deal database and quarterly SaaS reports) that make it one of the most-cited data sources in the category. SEG's process pitch is that 60% of sellers fail to transact without a structured process, so it engineers buyer competition and, notably, will tell a founder to wait if timing is wrong. Its vertical coverage spans education, healthcare, government, manufacturing, energy and proptech software.
2 L40 Partners
Best for: profitable SaaS founders whose buyer list should include European or Latin American strategics and sponsors, not just US names.
L40 Partners is a technology, software and AI M&A advisory firm operating under the SEC M&A broker exemption, with offices in Miami, Lisbon and Madrid. Its sell-side page states typical SaaS ranges of $5M-$100M ARR with strong net revenue retention and low churn, and the firm reports 180+ transactions closed across the US, Europe and LatAm, every mandate partner-led. Published deals include KrakenD (acquired by Shop Circle), FirstPromoter (acquired by SpringWater) and Big Red Cloud (acquired by Melior Private Equity). The firm's process runs four phases from positioning through data-room-led close, and its Tech M&A radar publishes the buyer-geography data it works from. If your best buyer might sit in Europe, this is the firm on this list built for that.
3 Windsor Drake
Best for: founder-led fintech, payments and B2B software companies that want a conflict-free, senior-led sell-side process.
Windsor Drake represents owners selling founder-led and family-owned companies and does not represent acquirers. Its site states mandates in fintech, payments and technology with enterprise values between $5 million and $300 million, sector coverage of fintech, payments, B2B software, cybersecurity and AI software, and a six-phase process planned across roughly nine months. Founder Jeff Barrington leads every engagement from New York and Toronto and runs the firm's research program, including the Fintech Exit Index. Two things stand out for a profitable SaaS seller: the firm publishes its fee schedule up front, and it takes on few clients by design so senior bankers stay on the deal.
4 Vista Point Advisors
Best for: founder-led software and internet companies that want unconflicted advice and a US and UK buyer process.
Vista Point Advisors, headquartered at 555 Mission Street in San Francisco, is a technology investment bank for founder-led software, AI and internet companies that works exclusively for sellers. Its site frames the pitch as "we've chosen a side, it's yours": senior leadership stays engaged through the process and the firm does not represent buyers. Recent published transactions include Countfire (acquired by Valsoft, London), Bonsai (acquired by Zoom), Waitwhile (acquired by Allegion) and Book Creator (acquired by Kami, Bristol). Vista Point does not publish a deal-size range, so ask directly; the deal list suggests mid-market SaaS with a mix of strategic and sponsor buyers.
5 AGC Partners
Best for: profitable SaaS companies large enough for a sponsor-driven auction with senior partner attention.
AGC Partners is a partner-owned technology boutique founded in 2003, with over 585 transactions completed and a 70-member team across Boston, New York, London, Silicon Valley, Los Angeles, Minneapolis, Denver and Chicago. It covers M&A, growth equity, sell-side advisory and recapitalizations, and its stated model is partner-led execution with senior relationships at strategic acquirers and financial sponsors. AGC's London office gives it European reach that most US tech boutiques lack. For a founder-owned SaaS company at the larger end of the mid-market, AGC is one of the most-referenced names among sponsors.
6 iMerge Advisors
Best for: software companies in the $3M to $50M ARR band that want partner-led execution and a shorter process.
iMerge Advisors is a boutique M&A advisor for software, SaaS and AI companies with offices listed in Boston, Dallas, Seattle and San Francisco. Its site publishes a working range of $3M to $50M ARR, 150+ deals managed, $1B+ in transaction value, a 93% close rate and 25+ years of specialization, and states that every engagement is led directly by the two most senior people at the firm rather than delegated. Its Synoptic M&A process front-loads diligence into the first two weeks and targets a three-to-five-month close. For a smaller profitable SaaS company that would be an afterthought at a larger bank, iMerge is a credible option.
7 Shea & Company
Best for: established software companies preparing a sponsor-heavy liquidity process.
Shea & Company is a software-focused investment bank founded in 2005 with offices in Boston and San Francisco, and it reports over $50 billion in completed transactions with clients across North America, Europe, Israel and APAC. Its senior team came out of Credit Suisse First Boston, Hambrecht & Quist, JPMorgan, Morgan Stanley and Robertson Stephens, and the firm's stated thesis is combining boutique sector depth with bulge-bracket process execution. Shea is at its best on private-equity-driven software sales and recapitalizations; a founder with a $30M+ ARR business and a sponsor buyer universe should have it on the list.
8 FE International
Best for: smaller profitable SaaS, e-commerce and content businesses, and founders who want a high-volume advisor with global reach.
FE International, founded in 2010 and headquartered at 75 Rockefeller Plaza in New York with locations in London, Miami, San Francisco, Warsaw and Mumbai, reports over 1,500 transactions completed with a combined value of more than $50 billion and a 94.1% close rate. It runs private sales and acquisitions for technology businesses, a middle-market investment banking arm (FE Capital Markets), due diligence services and a self-serve M&A platform. FE is the volume player on this list: strong for a $2M to $15M ARR SaaS business, and its investment banking arm covers larger deals. Founders who want a partner living in the deal every day should weigh that against the throughput.
9 Union Square Advisors
Best for: larger enterprise software and infrastructure companies with strategic acquirers in play.
Union Square Advisors is a technology-focused investment bank founded in 2007 by Carter McClelland and Ted Smith, with offices in San Francisco and New York. Its site reports 198 strategic transactions since inception valued in excess of $125 billion, across AI and ML, enterprise applications and data infrastructure, cybersecurity, healthtech, GRC, vertical software, industrial tech and office-of-the-CFO software. The firm positions itself on senior-banker-led execution and an "AI plus human intelligence" process. For a profitable SaaS company at $50M+ ARR with public strategics on the buyer list, Union Square is one of the more experienced independent names.
10 GP Bullhound
Best for: SaaS companies with a European buyer universe or a European founder selling to US acquirers.
GP Bullhound, founded in London in 1999, reports 700+ transactions worth $58 billion, 180+ employees and 13 offices including San Francisco, New York, Stockholm, Berlin, Paris and Madrid. Its Business Software & AI practice publishes a steady stream of sale and growth-investment announcements (Peak to UiPath, BrightAnalytics with PSG Equity, Sdui with Bain Capital). GP Bullhound also manages investment funds, which a seller should understand going in. It rounds out this list as the European-rooted alternative to L40 Partners for a profitable SaaS company that expects a continental buyer.
How to choose an M&A advisor for a profitable SaaS company
For a profitable, founder-owned SaaS company, three questions matter more than the league tables.
- How many software companies did the firm sell in the last two years, and can you see them? Software Equity Group, L40 Partners, Vista Point Advisors and iMerge Advisors publish deal lists. Ask for the ones with metrics like yours.
- Who runs the deal after the pitch? Windsor Drake, L40 Partners and iMerge Advisors state that a partner runs every engagement. At larger banks ask, by name, who will be on the weekly call.
- Where should the buyer list reach? If your customers or competitors are in Europe, a firm with bankers there (L40 Partners, GP Bullhound, AGC Partners) can add strategics that a US-only shop will not know. Compare valuation ranges first in EBITDA multiples by industry.
