Investment thesis

24Haymarket follows a strict investment thesis focused on verticals in the nascent stages of high growth, where it can leverage proprietary insight from its Investor Network. The firm targets companies that have demonstrated initial commercial traction. It pursues an active investment philosophy, seeking a board seat in each investment alongside a hands-on, involved post-investment model. The firm makes initial investments with capacity for follow-on funding, leads rounds, and syndicates the capital of its sophisticated private investors, who commit their own money to each deal. 24Haymarket emphasises speed, aiming to complete within six weeks of first conversation.
