Description

ACF Investors, formerly known as the Angel CoFund, is a prominent UK-based venture capital firm specializing in co-investments alongside established syndicates of angel investors. Established in 2011, the firm plays a crucial role in supporting high-growth British businesses by combining institutional capital with the deep sector expertise and hands-on guidance provided by angel networks. Their unique model leverages the strengths of both venture capital and angel investing, aiming to provide more robust funding rounds and strategic support for promising startups across various sectors within the United Kingdom.

The core of ACF Investors' strategy revolves around partnering with experienced angel syndicates who have already conducted initial due diligence and committed their own capital. This collaborative approach ensures that ACF Investors backs companies that have already garnered significant private investor confidence and benefit from a network of seasoned entrepreneurs and industry experts. While their average investment stands at approximately £500,000 (around $635,000 USD), they demonstrate flexibility, capable of deploying cheques ranging from £100,000 (approximately $127,000 USD) up to £1.5 million (approximately $1.9 million USD) in initial rounds. This range allows them to participate in a variety of early to growth-stage funding rounds, complementing the angel investment.

Since its inception, ACF Investors has made a substantial impact on the UK's startup ecosystem. The firm has invested over £100 million into more than 100 companies, a testament to their consistent activity and commitment to fostering innovation. Crucially, these investments have successfully leveraged over £1 billion of private capital from their angel syndicate partners, significantly amplifying the funding available to their portfolio companies. By acting as a catalyst for further private investment, ACF Investors not only provides capital but also helps validate and attract additional funding, positioning their portfolio companies for sustained growth and success.
