It all started when I knocked on a door in Palo Alto. I noticed the little llama icon on the door & remembered how much I loved the product. Michael opened the door & welcomed me in. That is how I became friends with the Ollama founders, Jeff Morgan https://www.linkedin.com/in/jmorganca/ & Michael Chiang https://www.linkedin.com/in/mchiang0610/ . Since then, I have migrated most https://tomtunguz.com/localmaxxing/ of my workloads to Ollama https://tomtunguz.com/tags/local-ai/ ; it turns out I’m not alone. More than 8.9m developers use Ollama, a number growing by nearly one million every week. These users run Claude Code, Codex, OpenClaw, Hermes, & 65,000 more applications & integrations on top of Ollama. Ollama makes AI simple. Download the app & start running AI on your laptop in seconds. Here it is running on my Macbook : I run open source models locally for 70-80% of my work & then burst to the Ollama cloud for complex tasks ; a cloud that is twice as fast as others. 85% of the Fortune 500 uses Ollama across healthcare, finance, & energy. We found Ollama monitoring electricity loads at a powerplant in Finland ; at a space agency in the USA ; in the CFO’s office at a public company validating financials ; & even at a particle accelerator. Data never leaves the user’s machine when running locally. Businesses can customize their AI & own it.
