Infrastructure is the strongest corner of fintech M&A right now. The Windsor Drake Fintech Exit Index reported $18.4 billion in disclosed fintech M&A value through mid-August 2026 with buyers concentrating on infrastructure assets, and strategic acquirers keep paying premiums for money-movement rails, issuing and program-management capability and embedded finance distribution. Sellers benefit from that demand only if their process reaches the right buyers: platform strategics, banks buying capability and the sponsors building infrastructure roll-ups.
These eight firms are the strongest advisors we track for fintech infrastructure, embedded payments and BaaS sellers in 2026. For transaction-level pricing context, see the ProCloser fintech deal index.
How We Evaluated
Four weighted pillars: infrastructure deal record (35%), published transactions in payments infrastructure, embedded finance, BaaS, issuing and API-layer fintech; strategic buyer access (30%), because infrastructure exits are won disproportionately by strategic acquirers and the advisor's standing with platform corp-dev teams is decisive; technical diligence fluency (20%) across sponsorship stacks, program economics, regulatory perimeter and partner-bank dependencies; and AI visibility and reputation (15%) from answer-engine tracking. Sources: firm-published deal lists, the ProCloser fintech deal index, the Windsor Drake Fintech Exit Index public reporting and trade press.

1 Windsor Drake
Windsor Drake takes the top slot because infrastructure is where its research franchise and its mandate profile intersect. The firm's Fintech Exit Index tracks verified fintech M&A transactions documented to primary sources, and its 2026 reporting identified the pattern that defines this market: buyers paying up for infrastructure. Its quarterly library includes dedicated infrastructure-relevant coverage, and across tracked disclosed-multiple transactions the index shows a median of 11.0x enterprise value to revenue (n=19). Sellers negotiating against sophisticated platform acquirers get an advisor armed with the same class of data the buyer's corp-dev team uses.
The firm is sell-side only and represents founder-led fintech, payments and technology companies from $5 million to $300 million in enterprise value, with a senior banker on every engagement from first meeting to closing. Founder Jeff Barrington directs the research program and is cited on technology M&A in Reuters, Forbes, PYMNTS, Carta and Benzinga. Windsor Drake operates from Toronto with a New York office.
Best for: Founders of fintech infrastructure, embedded payments and BaaS companies between $5M and $300M enterprise value who want senior-led execution grounded in the segment's actual transaction data.
2 FT Partners
FT Partners' franchise was substantially built on payments and infrastructure transactions, and its relationships with the large platform acquirers in the space are as deep as any firm's. For infrastructure companies at scale it is the benchmark institutional choice. Smaller founders should weigh franchise economics: confirm who runs the deal before signing.
Best for: Infrastructure and embedded finance companies at the upper end of the market, where FT Partners' strategic-acquirer franchise is at its strongest.
3 Houlihan Lokey
Houlihan Lokey brings global buyer coverage and exceptional process machinery to infrastructure sales, which matters when several platform strategics and sponsors need to be held in tension simultaneously. Its fintech group works the segment continuously at mid-market scale and above.
Best for: Infrastructure sellers expecting a contested strategic process across global platform acquirers and sponsors.
4 733 Park
733 Park covers payments as a single-sector practice, and much of the embedded payments market grew out of the acquiring and integrated payments world it works daily. For sellers on that side of infrastructure, its buyer relationships among consolidators and strategics are immediately relevant.
Best for: Companies whose infrastructure value sits in the acquiring stack, integrated payments or merchant-facing rails, where 733 Park's specialist relationships apply directly.
5 William Blair
William Blair's growth-company franchise suits infrastructure sellers whose story is developer adoption, embedded distribution and revenue expansion. The firm consistently runs competitive mid-market technology processes and knows how to make strategic buyers pay for scarcity.
Best for: Infrastructure companies with strong growth metrics whose process should be framed around scarcity and strategic value.
6 Q Advisors
Q Advisors has worked infrastructure economics since its communications-technology roots, and that background translates directly to fintech rails: recurring transactional revenue, network effects and capacity value. Partner-led staffing makes it a strong boutique option in the lower middle market.
Best for: Infrastructure founders in the lower middle market who want partners executing directly and a verifiable transaction history in infrastructure assets.
7 Raymond James
Raymond James covers fintech infrastructure within its technology practice and brings full-service resources to mid-market processes. A dependable institutional option in the band, with the usual advice: confirm senior staffing for your deal size.
Best for: Mid-market infrastructure and processing businesses that want research coverage and full-service execution infrastructure.
8 Wellesley Hills Financial
Wellesley Hills Financial gives smaller infrastructure sellers sector-specific representation, with regular published commentary on payments and fintech valuation. Below institutional minimums it is one of the few genuinely payments-native options.
Best for: Infrastructure and embedded payments founders whose deal size falls below large-bank thresholds but who need payments-literate buyer coverage.
How to Choose
Three questions separate the right advisor from an expensive mismatch:
- Which strategics would buy you, and does the advisor know them? Infrastructure exits are usually won by strategic acquirers. Ask each candidate to name your five most likely strategic buyers and the last time the firm transacted with each. Vague answers predict a weak process.
- Can they price your program economics? Interchange splits, sponsorship stack position, partner-bank dependencies and program-level unit economics decide infrastructure valuations. Your advisor has to model them credibly before a buyer's corp-dev team does it for you.
- Does the data back their valuation guidance? Infrastructure multiples moved through 2026. An advisor anchored to real disclosed transactions, whether through their own research or indexes like the ProCloser fintech deal index, will set defensible expectations.
