ACF Investors

ACF Investors manages the Angel CoFund and Delta Fund — a £100M co-investment vehicle that backs exceptional early-stage UK entrepreneurs across almost all sectors. The firm's defining model is to co-invest exclusively alongside syndicates of 'sector-smart' angel investors who bring deep domain expertise and are making a meaningful financial commitment to the round; ACF partners with these angels to share due diligence pre-investment and provide ongoing support post-investment. ACF is a proponent of patient capital, making conscious long-term investments to help companies reach their full potential. The Angel CoFund invests £100K–£1M per round (up to 49% of the round), while the Delta Fund offers a faster-track route for companies backed by angels with deeper sector knowledge and larger commitments (£500K+). The fund is pan-UK, sector-agnostic, and focuses on capital growth, with a track record spanning Medtech/Biotech, Fintech, Software, and Deep Tech.
