Attack Capital is a YC alumni-founded AI venture studio that builds AI-native vertical SaaS in 30 days and invests in YC startups. It combines a rapid 30-day build cycle with an accessible AI fund to provide dual build-and-invest capabilities for founders and investors.

The studio validates ideas through customer discovery, executes a 30-day AI build cycle to launch an MVP with AI engineering and GTM execution, and provides ongoing hiring and fundraising support. It operates as both a venture builder and an investment vehicle, offering pre-seed and seed investments in YC companies, direct access to YC Demo Day deal flow, and follow-on network introductions for portfolio companies.
