Accelerator for early-stage founders, offering 12-week intensive program, up to $1M funding, and mentorship for product development.
a16z Speedrun SR007 is a 12-week accelerator program administered by Andreessen Horowitz that guides early-stage founders through rapid product development, go-to-market strategies, and fundraising. The San Francisco-based program accepts rolling early applications for its seventh cohort before the formal window opens in April 2026, targeting all startup categories including frontier AI, consumer technology, and interactive entertainment. Selected companies receive up to $1 million in total funding, structured as a $500,000 upfront investment for 10% equity via a standard SAFE agreement and an additional $500,000 allocation for their subsequent financing round. Participants also gain access to more than $5 million in vendor credits from recognizable technology partners such as AWS, Google Cloud, OpenAI, and Nvidia. This resource is intended for pre-seed and pre-launch founders requiring capital, expert mentorship, and structured acceleration to transition from initial concept to market readiness.
a16z Speedrun is Andreessen Horowitz's accelerator for AI-native startups, now in its seventh cohort (SR007). The 12-week program runs from San Francisco with the application deadline on April 30, 2026. Each company receives $500,000 for 10% on a post-money SAFE, plus a guaranteed $500,000 follow-on in the next round within 18 months.
On top of the investment, Speedrun provides over $5 million in cloud, AI, and software credits, plus priority access to model providers and app distribution channels.
Beyond the $1M in total committed capital, Speedrun provides access to a16z's full platform - including go-to-market teams, recruiting support, technical advisors, and the firm's extensive network of enterprise customers. The credits package includes compute from major cloud providers, API access to leading AI model providers, and distribution partnerships with app stores and social platforms. The program culminates in a demo day with the a16z partnership and their LP network.
Speedrun targets technical founders building AI-native products - not companies that bolt AI onto existing workflows, but startups where AI is the core product architecture. The strongest applicants have deep ML or AI engineering backgrounds and a clear vision for how their product changes what is possible. Focus areas include AI infrastructure, developer tools, vertical AI applications, and consumer AI products. Pre-seed to seed stage with a working prototype is ideal.
a16z values velocity and technical depth. Show them a working demo, not a pitch deck. If you have users, share engagement metrics. The Speedrun team reviews thousands of applications per cohort, so lead with your strongest technical insight and what makes your approach to AI fundamentally different from alternatives.
