Launched in 2023, a16z Speedrun is a 12-week accelerator from Andreessen Horowitz built for early-stage founders at the intersection of technology, AI, and entertainment. Despite being new, it has already deployed over $100 million into more than 120 startups, quickly becoming a launchpad for fast-moving innovation.
Speedrun runs two cohorts each year — a summer batch in Los Angeles and a winter batch in San Francisco. The program focuses on next-gen tools, 3D, gaming, XR, and platforms shaping the future of creative and AI-powered industries.
Founders accepted into Speedrun receive funding plus direct access to a16z’s global network of operators, product leaders, and investors. The curriculum is built around rapid product validation, go-to-market strategy, and scaling in competitive environments, supported by 1:1 mentorship and peer learning.
Applications are open to founders from anywhere in the world.
