If you are a founder, CEO, or investor exploring a sale, acquisition, or recapitalization in 2026, Boston is one of the most active middle-market M&A hubs in the country. The region's combination of tech, life sciences, fintech, SaaS, and payments companies has created a dense ecosystem of boutique advisory firms, each with a specific niche and a different approach to getting deals done.
This guide covers the boutique M&A firms serving the Boston and New England market in 2026. It is written for founders and operators who want to understand who does what, what each firm specializes in, and how to choose the right advisor for a transaction in the $2M to $350M enterprise value range.
What counts as a boutique M&A firm?
A boutique M&A firm is a privately held advisory firm focused on a narrow set of industries, deal sizes, or transaction types. Unlike bulge-bracket investment banks or middle-market banks, boutiques typically employ 5 to 50 professionals, focus on one or two industry verticals, lead deals in the $2M to $500M range, give clients direct access to senior partners, and operate on success-fee economics with smaller retainers. Boutiques often win on sector depth, speed, and partner attention. They lose to larger banks on brand prestige and international reach.
Criteria for this list
Firms included maintain a physical presence or active client base in the Boston and New England market, lead sell-side or buy-side M&A engagements as a primary line of business, focus on middle-market deals under $500M enterprise value, and operate independently rather than as a division of a larger institution. Firms are listed alphabetically to avoid false precision in ranking.
The firms
733Park
Focus areas: Payments, fintech, AI, SaaS. Deal size: $2M to $350M enterprise value, most commonly $2M to $80M. Services: sell-side advisory, buy-side advisory, growth and exit-readiness consulting. 733Park is a Boston-based boutique M&A and consulting firm led by founder Lane Gordon, whose 25-year M&A career began in merchant portfolio and ISO transactions. The firm represents companies for sale, helps acquirers source and close targets, and consults on exit readiness and growth strategy. 733Park is not a FINRA-registered broker-dealer, which limits the firm to M&A advisory rather than fundraising and keeps cost structures lean.

How to choose the right boutique for your deal
Choosing an M&A advisor is about fit, not the biggest name. Evaluate firms across five dimensions: sector depth (has the firm closed three or more deals in your specific niche in the last 24 months), deal size fit, who actually runs the deal day to day, process approach (broad auction, targeted outreach, or direct negotiation), and fee structure.
Frequently asked questions
What does a boutique M&A firm actually do?
A boutique M&A firm represents one side of a transaction and manages the full process: valuation, preparing marketing materials, identifying and contacting counterparties, negotiating terms, and coordinating due diligence and closing.
How much does it cost to hire a boutique M&A firm?
Most boutiques charge a monthly retainer plus a success fee tied to closed transaction value. The success fee typically ranges from 1% on very large deals to 8% on smaller deals.
How long does an M&A process take?
A typical sell-side process runs 6 to 9 months from kickoff to close. Buy-side engagements often take 9 to 15 months because the target search adds time.
Are Boston M&A firms FINRA-registered broker-dealers?
Some are, some are not. FINRA registration is required for firms that raise capital. Many M&A-only firms operate outside FINRA, which is legal for pure M&A advisory. This is a firm structure choice, not a quality signal.
