Hi, I'm Diego. I build AI companies, back the founders building the next ones, and help run the largest community of AI builders in the world. Before investing I founded and scaled companies, and shipped data products used by hundreds of millions of people. Here's what I'm working on:
π¨ AI Tinkerers Fund : Pre-seed fund backing AI/ML founders at the earliest, messiest, most fun stage.
π AI Tinkerers : Global community of 114,000+ AI builders across 245 cities. The best demo nights on earth.
π Stanford GSB : Executive Fellow teaching Applied AI and running Startup Garage (STRAMGT 546).
ποΈ Work-Bench : Venture Partner backing enterprise infrastructure and AI startups.
π‘οΈ Guardrails AI : Co-founder. Open source guardrails for LLM applications.
π§ Algorithmia : Founder and CEO. One of the first ML model deployment and serving platforms. Acquired by DataRobot, where I stayed on as EVP.
π Microsoft : Product lead on Excel, SQL Server, and Power BI. Building Excel is still one of the most meaningful things I've done.
