Alex Langshur is Co-Founder and CEO at Antioch, the leading simulation platform for physical AI development, enabling robotics and autonomy teams to build, test, and validate autonomous systems before real-world deployment.

Alex studied Computer Science at Stanford University (Class of 2021) and previously served as Head of Product at Deep Grey Research, where he developed deep expertise in AI and data infrastructure.

A self-described tinkerer with a highly technical background, Alex believes scalable simulation is now the rate-limiting step for reindustrialization and that reliable automation is critical to national competitiveness.

Alex is a second-time founder who previously co-founded and led Transpose, a blockchain data platform acquired by Chainalysis, demonstrating a track record of building and scaling developer-focused data tools.

Antioch has raised $44.75M in total funding including a $32M Series A led by Greylock, and counts Amazon Ring as a customer and NVIDIA and Nebius as strategic partners.
