Saad Jamal is the Co-Founder and CTO of Antigen, a Y Combinator-backed AI cybersecurity company delivering continuous offensive security for the enterprise.

Saad built ML infrastructure at Tesla Autopilot for three years and later trained reasoning models alongside Ashish Vaswani, author of the seminal Attention Is All You Need paper, before dropping out of UChicago Law School to pursue Antigen.

Saad and his co-founder have collectively earned over $200K in bug bounties through security research, and his drive is captured in his own words: "Determination is everything, much more than intelligence."

At Nuro, Saad developed an ML Compiler framework enabling perception across multiple GPUs, and at Tesla he built training infrastructure that halved the time to train Planning and Controls models, demonstrating deep systems-level expertise.

Antigen has raised $4M at a $30M valuation, backed by Y Combinator, Lightspeed, DST Global, and Susa Ventures, and has already helped prevent up to 200,000 social security numbers from being exposed.
