Founded in 1986 within the Family Office of the late Honourable Averell Harriman, a former partner of Brown Brothers Harriman. Winchester Capital is focused on cross border mergers and acquisitions, private equity and asset management. We are a private company located adjacent to the Yale University Campus in New Haven, Connecticut, USA and in St James’s Square in London, England. We focus on research, strategic financial services and private international asset management. Over the past 35 years, we have been at the forefront of some of the world’s largest and most complex transactions in over 40 countries.

Our professional services and asset management are supported by expert research, diligence and valuable commercial intelligence provided by our in-house team of professionals. Our clients are sophisticated investors including banks, family offices, institutional investors, multinational corporations.

We are the first company in our class to provide the comprehensive WinStar® M&A Global Resource to international clients which assists all phases of M&A transactions as a resource and consulting service, without a buy side or sell side mandate. This assists a buyer or seller with pre-market research and advice on all steps of the process before brokers are appointed. It also facilitates technology transfer from University based research to potentially realize value.

Our asset management includes the acquisition and management of direct and indirect private equity portfolio interests. We acquire these interests from banks, insurance companies and other investors who seek liquidity to conform with regulatory compliance and decrease management costs. We are able to uniquely combine our M&A execution capabilities with portfolio management to deliver value, especially with late vintage assets.
