Attack Capital

Attack Capital is the only Y Combinator-backed AI venture studio designed for founders who want to build and invest with speed. We combine a disciplined 30-day build cycle with an accessible AI fund giving investors direct access to YC startups.

Join the leading AI venture partner building the next generation of AI-native SaaS companies.

Understanding YC: The World's Most Valuable Startup Ecosystem

Y Combinator invests twice a year into early-stage companies through a 3-month program focused on rapid growth and fundraising. YC Demo Day access is restricted to a curated list of investors, making it difficult for most individuals to invest in AI companies or invest in YC companies at the earliest stages.

Attack Capital’s AI fund opens access to YC-backed startups, allowing investors to participate in Y Combinator backed companies through a transparent and accessible structure.
