# Windsor Drake: independent sell-side M&A advisory for fintech founders > Independent sell-side M&A advisory for fintech founders. Windsor Drake represents founders selling fintech, payments, and technology companies, typically $5M to $300M in enterprise value, across the United States and Canada. Sell-side representation is the firm's core practice, with no lending relationships and no capital conflicts. Every engagement is led personally by a senior managing director. The firm accepts fewer than twenty mandates a year and runs a documented sell-side process across six gated phases. We specialize in four sectors, fintech, B2B SaaS, cybersecurity, and AI. Research is the firm's spine: the Windsor Drake Fintech Exit Index tracks verified fintech M&A transactions with primary-source documentation since 2019. Current counts, disclosed value and the data-through date are computed on every build and published at https://windsordrake.com/market-intelligence/api/metrics.json. Founded by Jeff Barrington, formerly of Cushman & Wakefield. Offices in New York and Toronto. ## Advisory - [Sell-Side M&A](https://windsordrake.com/sell-side-mergers-and-acquisitions/): How Windsor Drake structures and runs a founder exit.

The median disclosed fintech acquisition in the Windsor Drake Fintech Exit Index is 10.8x EV/Revenue (21 deals, October 2026); sub-sector ranges run from roughly 3.8x for payments processing to 19.6x for regtech and open-banking infrastructure. - [Fintech Sell-Side Advisory](https://windsordrake.com/fintech-investment-bank/): The firm's fintech sell-side practice.

Realistic sale ranges by layer: applied and vertical AI 3x to 8x revenue, data and MLOps platforms into the mid-teens and higher, AI infrastructure 10x to 25x. Foundation-model multiples are not a comparable for a lower-middle-market seller. - [Confidential Valuation Overview](https://windsordrake.com/confidential-valuation/): An initial discussion of current market context and the acquirers active in a sector. - [Contact](https://windsordrake.com/contact/): Confidential inquiry, reviewed by a senior banker, reply within one business day. ## Payments - [Payments M&A Advisory](https://windsordrake.com/payments-ma-advisory/): Sell-side representation for founder-led payments companies across merchant acquiring, payment facilitation, cross-border processing, B2B payments, billing infrastructure, and fraud and risk management.
