Ollama raises $65M Series B as local AI adoption hits 8.9M monthly developers
Ollama, a developer platform for running open-weight AI models locally, closed a $65 million Series B funding round led by Theory Ventures, with participation from Benchmark (which led Series A), 8VC, Y Combinator, Pace Capital, and others. The round brings total funding to $88 million. Ollama makes it simple for developers to download and run open models on their own machines with a single command, or scale to larger models running on Ollama's cloud infrastructure.
Ollama's growth has been explosive: monthly active developers have reached 8.9 million (doubled since January 2026), with nearly 1 million new installs per week. The platform is now used within 85% of the Fortune 500, including customers in regulated industries like government, healthcare, and finance. Over 67,000 community-built integrations exist, and Ollama partners with every major open model lab (Meta, Google DeepMind, Mistral, MiniMax) and hardware vendor (NVIDIA, Intel, AMD, Qualcomm) for day-zero model access and optimized performance.
Benchmark General Partner Peter Fenton (on the board) has articulated the market thesis: 'Open-weight models will generate the supermajority of tokens within the next 18 to 24 months.' The funding will scale Ollama's cloud compute footprint, support product development, and fund key team hires. Founded by Jeffrey Morgan and Michael Chiang (who previously built Kitematic, acquired by Docker and later became Docker Desktop), Ollama positions itself as the platform layer for local and hybrid AI inference—abstracting away complexity so teams can run models without reliance on closed frontier labs.
For practitioners: Ollama's 8.9M MAD and 85% Fortune 500 adoption signal that local open-model inference has crossed from niche to mainstream in enterprises. This validates the broader shift away from pure API dependency on OpenAI/Anthropic. Key takeaway for stack builders: the distribution and orchestration layer for open models is now a VC-backed, well-funded platform play—a 'picks and shovels' winner in the open-model era.
