a16z opens applications for Speedrun Residency Phase 8, project to take place from February 1 to April 16, 2027 in new San Francisco office
Andreessen Horowitz's Speedrun project has opened applications for its eighth phase (SR008), with a deadline of November 1, 2026. The project will take place from February 1 to April 16, 2027, in a new office in San Francisco.
Andrew Chen announced that recommendations are being accepted and he will personally collaborate with founders on growth, distribution, and financing matters. The standard deal involves a maximum investment of $1 million: $500,000 through SAFE for 10% equity, with an option to add up to $500,000 in the next round within 18 months; no board seat is taken, and subsequent rounds have priority subscription rights. Selected teams will also receive over $10 million in cloud, AI, and software credits from more than 200 partner companies.
The residency lasts twelve weeks, full-time in San Francisco, starting with a founder retreat from February 2 to 4 and ending with a demo day on April 13, showcasing to thousands of investors. The project provides capital, customer, and talent support: on the customer side, access to over 150 C-level founding members and more than 1,000 executives and operators through the SR Insiders network, along with events like AI Faire, Tech Week, Launch Lab, and Brand Lab; on the talent side, access to a network of 171,000 and recruitment and HR support. Since its launch in 2023, Speedrun has deployed over $180 million to more than 200 startups.
Each recent batch accepts 70 to 80 companies, with an acceptance rate of less than 0.4%; the previous batch, SR007, received over 30,000 applications. The project has expanded from its initial focus on gaming and entertainment to cover a range of sectors including AI, defense, and satellites, and has opened a dedicated office in Jackson Square, San Francisco, as the residency venue.
In terms of market mechanisms, the event serves as a targeted allocation of early capital and resources: a16z locks in seed-stage equity through fixed-terms SAFE and follow-on commitments, while reducing operational costs for founders with credits, customer networks, and talent pools. Funds flow from a16z to selected teams, benefiting founders with endorsements and follow-on financing channels, while the pressure point lies in the extremely low acceptance rate and the time cost of being full-time in San Francisco; the demo day concentrates subsequent financing needs and exposes them to external investors.

a16z launched Speedrun in 2023, initially extending from gaming practices, later expanding into technology and entertainment, evolving into a horizontal early-stage project; Andrew Chen leads the initiative as a general partner, emphasizing early involvement before or at the very early stages of company formation, providing ongoing follow-on investments and network support.
Capital is injected in the form of SAFE at the start of the residency, with follow-on investment amounts reserved, while resources flow into the credit market and internal talent network; the motivation is to quickly screen and bind high-potential teams with standardized terms against the backdrop of rising costs in AI and software, while reducing early control friction by not taking board seats.
This is similar to Y Combinator's fixed batch and demo day model, but Speedrun offers a higher equity stake, larger credits, and emphasizes the a16z brand and priority in subsequent rounds; it is currently in an expansion phase, transitioning from a pilot in Los Angeles to a dedicated office residency in San Francisco, and increasing student access to the Alpha channel.
Essentially, it represents capital concentration and industry chain restructuring: early funds concentrate dispersed founders into a unified residency and network through standardized transactions and resource packaging, changing the pricing of seed rounds and subsequent financing paths; the mechanism occurs because traditional angels and small funds struggle to provide capital, customers, and talent simultaneously, while large funds productize their networks in residency formats, creating a closed loop between early screening and follow-on investments.
