a16z Speedrun is Andreessen Horowitz's 12-week investment and mentorship program, originally focused on young founders and now open to startups across all industries. Each cohort accepts around 60 companies, each receiving up to $1M in investment.
Beyond capital, founders get 1:1 mentoring time with a16z executives and $5M+ in credits from OpenAI, Anthropic, NVIDIA, AWS, and Microsoft. The program runs in Los Angeles with two cohorts per year (Summer and Winter/Spring).
The a16z brand signal is unmatched. $5M+ in vendor credits provides significant runway for AI-heavy startups.
Early-stage founders across all industries who want the a16z signal and network. Larger cohort size means less personalized attention than smaller residencies.
The combination of a16z brand, massive vendor credits, and LA location (vs. SF-centric competitors) makes Speedrun unique in the residency landscape.
