Gain access to the world’s strongest startup ecosystem. When you invest in YC companies, you’re investing in the most successful startup accelerator in history. Y Combinator has generated over $800B+ in value and built a global network of YC-backed companies, unicorns, and breakout market leaders.
For decades, access to Y Combinator investment opportunities, including Demo Day, was limited to elite VCs and well-connected angels. Attack Capital removes that barrier. Through our YC Demo Day Access Fund, accredited investors can now invest in Y Combinator startups and the top-performing YC startup portfolio with a minimum investment of only $10,000.
Investors looking to invest in YC companies benefit from a track record no other accelerator or VC fund can match. Y Combinator consistently identifies category leaders early, creating exceptional venture returns, stronger than nearly any traditional VC fund. Attack Capital helps investors invest in YC portfolio companies backed by rigorous sourcing and alumni insights.
