Portfolio Ventures

Portfolio Ventures (PV) is a London-based early-stage venture capital firm founded in October 2014 by Will Martin and Will Brooks — two of the UK's most prolific angel investors, each having personally made over 100 early-stage technology investments. The firm is authorized and regulated by the UK Financial Conduct Authority and positions itself as the UK's best-connected early-stage investor, offering founders access to a curated network of over 1,000 strategic angel investors, family offices, and VCs. PV operates a dual model: the PV Angel Fund deploys GBP 100,000 to GBP 500,000 checks into UK-based fintech, insurtech, SaaS, and enterprise software companies, while a wider platform has helped 200-plus portfolio and network companies raise downstream capital. In 2022, PV closed its oversubscribed second Angel Fund at GBP 5 million or more, with James Pringle (founder of Pringle Capital and co-host of the Riding Unicorns podcast) joining for Fund II. The firm has made 46 disclosed investments. Notable portfolio companies include Tractable, ManyPets, Marshmallow (a UK unicorn that raised $85 million at a $1.25 billion valuation), OLIO, PensionBee (listed on the London Stock Exchange in April 2021 at a $520 million market cap), Attest, Ably, Elvie, and Credit Kudos (acquired by Apple). The most recent disclosed investment is an $8 million Series A in Bit Fount in July 2025. Portfolio Ventures believes that the founders with the best outcomes are those who combine ambitious product vision with a broad, trusted network — and its model is designed to deliver that network from day one. Will Martin and Will Brooks remain hands-on investors who leverage their combined 200-plus angel deals to provide warm introductions, secondhand experience of scaling challenges, and access to the co-investor relationships that accelerate subsequent funding rounds.
