Investment thesis

24Haymarket focuses on growth equity and venture capital investments in UK high-growth companies, investing aligned private capital to accelerate commercial success. The firm follows a strict investment thesis targeting verticals in the nascent stages of high growth — including digital healthcare, cybersecurity, climate tech, enterprise software, fintech, and supply chain — where it can leverage proprietary insight from its Investor Network of 100+ sophisticated, engaged private investors with 3,000+ years of collective experience. The firm invests only in companies that have demonstrated initial commercial traction (typically at least £1m in annual revenue), taking an active, hands-on approach with a right to a board seat in each investment and an involved post-investment model. Initial tickets range from £1m to £5m with follow-on ambition, targeting 15–20% minority stakes and aiming for 6–8 new investments per year.

24Haymarket has taken a different approach [to most angel networks], with a distinct philosophy — an early focus on experienced private equity professionals and investing at a much later stage than most angel networks.
