Noah Song is Co-Founder at Archal Labs, a YC S26-backed AI infrastructure company building the improvement loop for autonomous AI agents.

Noah studied mathematics at CU Boulder, earning recognition as the undergraduate student with the greatest promise in the mathematical sciences, and was admitted to a Ph.D. program in computer science at MIT.

Noah brings a rare blend of rigorous academic training and hands-on engineering experience, having led a 50-person team to develop an autonomously flying fixed-wing UAV as a senior project.

Prior to Archal, Noah contributed to developer tooling at Rowan, helping ship a major Python API update (v3.0.0) aimed at making computational tools more accessible to everyday programmers.

Archal tackles a critical gap in the AI agent ecosystem by automatically verifying agent actions and opening fix PRs when agents go off course, positioning the company at the frontier of reliable AI automation.
