Ollama, the open source AI tool that simplifies the process for developers to run advanced artificial intelligence models on their personal computers, has announced a significant $65 million (£51 million) Series B funding round. This latest investment, led by Theory Ventures, brings the company's total capital raised to $88 million (£69 million) since its inception in 2023. The platform has rapidly gained traction, with its GitHub repository accumulating 176,000 stars and nearly 17,000 forks, indicating strong community engagement and adoption.
The tool's primary appeal lies in its ability to enable developers to get open-weight AI models operational on their PCs within minutes, a process that was previously complex and geared more towards researchers. This ease of use has resonated widely across the developer community, leading to its adoption by over 8.9 million developers every month. Impressively, Ollama's reach extends to 85% of Fortune 500 companies, despite the company operating with a lean team of just 14 employees.
Ollama's founders, Jeff Morgan and Michael Chiang, are not new to making complex technology accessible. They previously played a pivotal role in developing Docker Desktop, a platform that similarly abstracted away hardware configuration issues, making cloud application deployment easier. This prior experience appears to have informed Ollama's mission to democratise AI development, allowing more programmers to experiment and build with open models, which began to emerge prominently in 2023 but were initially challenging to implement.
Beyond its core free offering, Ollama also provides developers with access to a 'neocloud' service, hosting larger and more intricate AI models. This service operates on various subscription tiers, ranging from free access to a top-tier option priced at $100 per month. The company differentiates its tracking of usage by focusing on GPU time rather than token limits, potentially offering a more transparent and cost-effective model for users with high inference expenses.
The investment underscores a broader industry shift towards open-source AI, driven by enterprises and AI application-layer startups seeking more affordable alternatives to proprietary models. While the debate between open and closed AI models continues, investors like Benchmark's Peter Fenton, who led Ollama's earlier Series A round, believe there is ample room for both. However, the increasing cost of inference for closed models is compelling many organisations to explore open-weight solutions, a trend that bodes well for Ollama's cloud business and the wider open-source AI ecosystem.
