What Exponent does

Exponent Private Equity LLP is a London-headquartered, FCA-regulated private equity firm founded in 2004 by a team including Tom Sweet-Escott, with a secondary Irish-regulated entity (Exponent Private Equity (Ireland) Limited, Dublin) established in 2023. Across five buy-out funds it has raised £3.8 billion in commitments, with Fund V closing at £900 million (over €1 billion) in July 2025, 20% above target, from a globally diversified LP base of pension funds, endowments, sovereign wealth funds and family offices. Exponent invests exclusively in 'primaries' — corporate, family and founder-owned mid-market businesses with enterprise values of €150-500m, headquartered in the UK, Ireland and the Benelux, across four stated core sectors (media, consumer, financial services, business services) and selected adjacent verticals such as pharmaceuticals, healthcare, engineering, IT services and data-centre infrastructure.

Exponent generates revenue through traditional private equity economics: recurring management fees on committed and invested capital across Funds I–V (Fund V alone represents over €1bn of fee-earning AUM), performance-based carried interest on exits, and capital gains from its own equity stakes realised through trade sales, IPOs, secondary block trades and recapitalisations. Its go-to-market is bifurcated: a direct, in-house Investor Relations team led by Partner Marius Østlie runs bespoke LP coverage globally, while an investment team of roughly 30 partners and operating professionals, supplemented by a proprietary Chairperson and Operating Partner network (including Alan Peterson OBE, Andrew Higginson, Jack Griffin, Niall Wall, Vagn Sørensen, John Moore, John Dwyer and others), sources and executes mid-market primaries and corporate carve-outs directly. The firm has completed nine corporate carve-outs over the last decade (most recently Optimas International, announced February 2026) and is differentiated by PRI signatory status and an SBTi-validated climate target (September 2024). Exponent has no public technology stack beyond its responsible-investment framework; the firm has no disclosed AI/ML capability, no public API, and does not publish pricing, relying on bilateral LP negotiations under private fund documents.
