EST Partners

Co-founders Henry Smithers and Matthew Eatough lead the firm. Smithers previously led UK Business Services M&A at Duff & Phelps and co-founded a VC-backed mobile loyalty platform. Eatough founded procurement advisory Proxima Group and chaired it until its sale to Bain & Company in 2022. The third co-founder, Mark, managed 11 professional-services mergers during his tenure as CFO and COO of BDO LLP.

EST Partners targets established founder-led or corporate-owned B2B services firms with at least £3M in revenue. It does not require profitability at entry and will invest in growth, late-stage, management buyout, succession, turnaround and corporate carve-out situations. The firm explicitly lists pre-IPO, PIPE, public-to-private and recapitalisation transactions within its mandate.

There is no ownership link between EST Partners and Bain & Company. The connection is through co-founder Matthew Eatough, who founded Proxima Group and chaired its board until Bain acquired it in 2022. Eatough uses that operational exit experience in the governance model EST Partners applies to its own portfolio companies.

EST Partners states it can write Day 1 cheques up to £25M with co-investment, compared to its standalone maximum of £5M. The firm also offers direct co-investment opportunities up to £3M, suggesting it both seeks and accommodates co-investor capital on larger transactions. The identity of its co-investor network has not been disclosed publicly.

EST Partners publicly focuses on B2B services within financial services, real estate and facilities services, and energy, renewable and waste services. It does not list consumer-facing, healthcare, or industrial manufacturing among its investment criteria. Sub-sectors such as pension administration, property surveying and sustainability auditing define the perimeter of its stated interest.

EST Partners is structured as a direct investment firm, not a fund-of-funds. Its website describes writing equity cheques directly into operating companies and deploying a proprietary automation toolkit post-close. There is no public indication that the firm commits capital to third-party private equity funds.

The firm's operational capability stems from its three co-founders. Matthew Eatough built Proxima Group to over 230 consultants and sold it to Bain; Mark oversaw 11 mergers as CFO and COO of BDO LLP; and Henry Smithers advised on professional-services M&A at Duff & Phelps. The firm says it deploys an automation toolkit from Day 1 of ownership, though the toolkit's specifics are proprietary.
