Ollama raises $65M as open models move into enterprise AI
Ollama’s Series B shows open-model infrastructure becoming a serious commercial layer for developers and enterprises seeking more control over AI deployment.
Open models are becoming a serious enterprise infrastructure category rather than a hobbyist alternative to closed APIs.
What happened
Ollama raised a $65M Series B led by Theory Ventures, with participation from Benchmark, 8VC, Y Combinator, Pace Capital and others.
The round brings total funding to $88M.
Ollama helps developers run open-weight AI models locally and through hosted infrastructure. The company reports nearly 8.9M monthly developers, use across 85% of the Fortune 500, and a team of 14 people.
Why it matters
The value is not another model. It is the infrastructure around finding, running and deploying open models.
As enterprises look for lower inference costs, more deployment control and alternatives to closed APIs, that abstraction layer can become strategically important.
The company’s reported developer adoption also suggests open-model tooling is becoming mainstream rather than niche.
The bigger picture
The AI stack is fragmenting across model providers and deployment environments.
Infrastructure that makes open models easier to use across local machines and cloud systems could become a major control point. Ollama’s funding reflects growing conviction in that layer.
