Ollama, a tool that makes it easy for developers to run open-source AI models locally or in the cloud, has raised $65 million（約100億円） to expand its platform.
The company has grown to serve more than 8.9 million monthly developers and 85% of Fortune 500 companies.
Its key advantage is seamless workflow continuity—developers can run the same command and API to switch between local and cloud models without managing separate relationships with different cloud providers.
What happened
Ollama Inc., a developer tool for running open-source AI models locally, raised $65 million（約100億円） in a Series B funding round led by Theory Ventures, bringing its total funding to $88 million（約140億円）. The company, which launched in 2023, now has more than 8.9 million monthly developers and is used by 85% of Fortune 500 companies.
Why it matters
Ollama lets developers download and run AI models on their own machines or in its cloud with a single command, competing with cloud-native inference providers like Fireworks AI and Groq. The company's strength lies in offering continuity—developers can swap from a local model to a powerful 400B cloud model with a single string change, avoiding the friction of switching cloud providers.
What to watch
Ollama offers a free cloud tier plus subscriptions up to $100 a month. The company reports its cloud has more than doubled in token volume every month on average. Open models available include GLM, Nemotron, DeepSeek, Kimi and MiniMax, with release-day access through partnerships.

Ollama's $65 million（約100億円） Series B funding signals investor confidence in a developer-centric approach to AI infrastructure that prioritizes ease of use and local-first deployment. The company has grown rapidly since its 2023 launch to become what the body describes as the largest network in the open model ecosystem, with over 67,000 integrations. The funding enables Ollama to compete directly with specialized cloud inference providers like Fireworks AI, Groq, and Together Computer, which charge on a per-token basis and emphasize speed and availability of frontier models.
Ollama's differentiation lies not in matching the raw performance of competitors but in offering developers a frictionless bridge between local and cloud workflows. By allowing the same command and API to seamlessly swap from a local 7B model to a 400B cloud model, the company removes the operational burden of managing separate cloud relationships. This is particularly valuable for the 85% of Fortune 500 companies now using the platform—enterprises in regulated industries like government, healthcare, and finance where operational continuity and control matter. The body notes that the company's cloud token volume has more than doubled monthly on average, suggesting rapid adoption of this hybrid model.
