a16z Open Source AI Grant
Runs No-strings grant funding community software projects AI developers small teams.
The a16z Open Source AI Grant program is a grant-based funding stream intended to support developers and small teams building open source AI stack components. It is structured as grant support, not investment, so recipients are presented as retaining ownership rather than signing into an equity-led deal. Andreessen Horowitz announced two batches in 2023, with Batch 1 released in August and Batch 2 in December. No third batch has been published through the latest crawl date in 2026. The program does not provide a general application portal, so it currently appears as a selective, batch-driven series rather than a continuous open roll. Teams with open source tooling of broad AI infrastructure relevance were the class highlighted in the 2023 materials.
No upcoming rounds verified. Cadence: One-off.
