ECI Partners

What ECI Partners does

ECI Partners is a UK mid-market private equity firm founded in 1976, headquartered in London with additional offices in Manchester and New York. It invests in management buyouts, buy-ins, and minority deals in growth businesses primarily in the UK, with an expanding European platform following the February 2026 acquisition of Netherlands-based Paragin. The firm has raised 11 private equity funds, with its current flagship ECI 12 closed at its £1bn hard cap in September 2023 and ECI 13 in preparation; £500m+ was deployed from ECI 12 in 2024. ECI has completed 267 investments and partnered with over 250 growth businesses over its 50-year history, generating returns of approximately 6.1x on Wireless Logic, 6.2x on Tusker, 6.1x on MiQ, 5.4x on Citation, ~6x on Games Workshop, 3.7x on ATG, 3.5x on CSL, 2.7x on Peoplesafe, and 2.5x on CliniSys, with five of the last seven funds delivering 2x money or 20% IRR or better. Operationally, ECI is structured around three internal teams — investment, commercial/value creation, and origination — and is led by four Managing Partners (George Moss, Christopher Watt, David Ewing, Thomas Wrenn) under a succession model in place since ~1990, with Steve Tudge as non-executive Chair.

ECI's revenue model is conventional private equity fund management: recurring management fees on committed and invested capital across multiple fund vintages, supplemented by transaction and monitoring fees, and carried interest tied to fund performance. Capital is sourced and deployed through direct, relationship-led origination backed by Amplifind™, an in-house AI-driven platform that combines a 35-year firmwide CRM, machine learning, deep research, and Agentic AI. The firm has extended this platform to portfolio companies as Amplifind™360, which it states is unique among UK mid-market PE firms. Distribution and deal flow are concentrated in the UK, supplemented by US cross-border capability through the New York office and a growing European pipeline. ECI is regulated by the Financial Conduct Authority (firm references 211137 and 812979) and has been B Corp Certified since November 2023. The firm does not publicly disclose fee schedules, fund terms, or consolidated revenue.
