Foundation Capital’s Build Accelerator

12.19.2025 | By: Alyssa Spagnolo

The first to believe

For more than 30 years, Foundation Capital has backed founders at inception, long before the rest of the world believed in them. Our Build Accelerator programs extend that tradition.

We support founders at the very beginning, when all you have is conviction in yourself to start and a rough idea.

No equity. No fees. No catch.

We offer you our belief in you as a founder, resources to turn a technical insight into a company, and a community of equally ambitious believers.

🌊 Why Build Accelerator?

The leap from zero to one is the hardest stretch of company building. You’re running on conviction with limited resources, a small team, and an endless to-do list. Our Build programs exist to give founders an unfair advantage in the earliest, loneliest part of the journey – when you’re transforming a spark of technical insight into a company that can scale.

When you join a Build program, you gain:
