Program details

The accelerator is structured to provide deep technical and business support specifically for the games industry.

Eligibility

SPEEDRUN is open to both new and experienced founders globally.

  • Stage: The program is ideal for "Day Zero" founders, pre-seed, or seed-stage startups.
  • Profile: a16z seeks technical founders, creative directors, and visionary operators. You do not necessarily need to have a fully formed company or a finished game to apply; many applicants enter at the "idea" or "prototype" stage.
  • Team: While solo founders are considered, there is a preference for teams with complementary technical and creative skills.

Structure and timeline

The program is designed as a fast-paced, 12-week experience culminating in a major demo day.

  • Format: A hybrid model featuring virtual sessions and in-person events at a16z’s offices in locations like San Francisco or Los Angeles.
  • Cohort Cycles: a16z typically runs two cohorts per year.
  • Demo Day: The program concludes with an exclusive Demo Day where founders pitch to hundreds of elite investors, including a16z partners and outside venture funds.

Benefits

Accepted startups receive a massive influx of resources and brand prestige.

  • Mentorship: Direct access to a16z general partners and industry veterans from companies like Riot Games, Blizzard, and Epic Games.
  • Community: Participation in an elite founder community, fostering long-term peer-to-peer support.
  • Partner Perks: Access to deep discounts and credits for game engines, cloud services, and specialized AI tools.
  • Post-Program Support: Graduates become part of the permanent a16z portfolio ecosystem, receiving ongoing support for future funding rounds.

Funding or investment terms

The financial commitment from a16z is standardized and substantial for early-stage teams.

  • Direct Investment: a16z typically invests $750,000 in every company that is accepted into the program.
  • Terms: The investment is generally structured as a SAFE or a similar equity-based instrument, ensuring founders have immediate capital to hire and build during the 12-week sprint.

Application and selection process

The selection process is extremely competitive, with thousands of applicants vying for approximately 30 spots.

  • Initial Application: Founders submit a brief form and a short video pitch explaining their vision and team background.
  • Interviews: High-potential candidates go through a series of technical and strategic interviews with members of the a16z Games investment team.
  • Selection Criteria: The team looks for "market-moving" ideas, technical excellence, and the ability to execute quickly (speed of iteration).

SPEEDRUN by a16z Games is perhaps the most prestigious accelerator for gaming and tech-adjacent founders. By offering a significant $750,000 investment alongside unparalleled access to industry legends, it serves as a high-velocity launchpad for the future of entertainment.
