Unlocking Success: A Guide to a16z's Speedrun Accelerator
TechCrunch details how Andreessen Horowitz’s Speedrun accelerator selects and supports startups. Launched in 2023, Speedrun is highly selective (the program said more than 19,000 startups pitched and the latest cohort accepted under 0.4%). The horizontal, ~12-week San Francisco program runs two cohorts yearly, typically accepting 50–70 startups per cohort and investing up to $1 million per company (commonly $500,000 up front for ~10% via a SAFE, plus a potential $500,000 on a follow-on round). Speedrun emphasizes complementary founding teams, early technical ability or market validation, and active founder engagement with a16z’s operating network. The article includes application tips from Joshua Lu (Speedrun GM and a16z partner) and a founder case — Smart Bricks’ Mohamed Mohamed — who announced a $5M raise led by Speedrun.
Speedrun is a high-profile, well-funded accelerator (a16z) that deploys meaningful capital and network resources to startups; its selectivity, investment terms and the fact it led a $5M raise for a cohort company make it noteworthy for founders and investors, though it is not a major industry policy or platform change.

a16z Speedrun: Apply by May 17
Andrew Chen, General Partner at a16z Speedrun, published a newsletter reminding founders that the application deadline for the SR007 cohort is Sunday, May 17 at 11:59pm PT. The Speedrun program targets very early-stage startups (including unincorporated teams and solo founders), selects founders globally, and runs as an in-person, 12-week program in San Francisco with visa support.
