sell-side M&A for founder-led companies

The Firm
An institutional process, brought to founder-led businesses.

Windsor Drake brings an institutional sell-side process to founder-led businesses — the kind of process usually reserved for far larger companies. Deep positioning, targeted buyer strategy, controlled outreach, engineered competitive tension, and senior attention at every step.

The firm advises founders exclusively on the sell side. No buyer mandates. No capital conflicts. No divided loyalties. One objective: the right outcome, on the right terms, with the process run properly.

Senior attention is the firm’s scarcest resource. It is reserved for a limited number of engagements each year, accepted only after a confidential preliminary assessment.

The process determines the outcome.
Preparation, judgment, and execution decide whether value is protected or surrendered. That is the entire purpose of a properly run sell-side process.
Why Windsor Drake

Institutional standards, without exception.

Founder-scale companies are poorly served. Generalist brokers cannot position a business credibly; large firms assign junior bankers to deals below their focus. Windsor Drake was built to close that gap — senior judgment and sector depth, applied to every mandate.

No conflicts
The firm represents sellers only — no buyer mandates, no referral arrangements that create incentives to reduce seller proceeds. Its only interest is the founder’s outcome.
Senior attention at every stage
A Managing Director leads buyer outreach, manages the process, and is present in every substantive negotiation. Engagements are not handed to a junior team after signing.
Deep sector focus
The firm concentrates on a small number of verticals rather than dozens. That concentration produces buyer relationships, transaction precedents, and valuation knowledge a generalist cannot replicate.
Process control as a value driver
Every process is structured to create and sustain competitive tension between buyers. Controlled timelines, disciplined information release, and direct negotiation preserve leverage that unmanaged processes surrender.
How We Work

The Windsor Drake process

01
Positioning & valuation
A detailed assessment of financial quality, revenue composition, customer concentration, growth trajectory, and competitive position. Valuation parameters are set from comparable transactions before any market contact.
02
Confidential information memorandum
A transaction-grade CIM that presents the business with institutional rigor: sector context, financial analysis, and a defensible growth narrative — designed to inform qualified buyers without disclosing sensitive data prematurely.
03
Targeted buyer identification & outreach
A curated buyer universe of strategic acquirers, financial sponsors, and sector operators, ranked by fit and acquisition capacity. Outreach is controlled and sequential, built to maximize competitive tension while protecting confidentiality.
04
Process management & negotiation
Offers are evaluated on total consideration, terms, certainty of close, and post-transaction implications for the founder. Information flow is controlled and negotiation is led directly, preserving leverage through the LOI and into diligence.
05
Diligence & close
Diligence is coordinated and the data room managed alongside legal counsel to protect terms through close. The engagement does not end at the LOI; senior attention remains on the transaction until funds transfer.
