Marc Papazian is Co-Founder and CEO of Propolis (YC X25), an AI-powered QA platform that deploys autonomous browser agents to simulate real users and eliminate manual software testing.

Marc studied at Harvard University and went on to serve as a deployment lead at Palantir, where he led the operational data backbone for the entire U.S. federal pandemic response.

A multifaceted builder, Marc also served as Director of Product at an AI startup and is a recreational beekeeper and winemaker in Armenia, pursuits that reflect his precision-driven, systems-thinking mindset.

Marc co-founded Propolis alongside Matt White, a former senior engineer at Airtable, combining their firsthand frustrations with slow QA cycles at Palantir, Airtable, and various startups into a unified product vision.

Accepted into Y Combinator's Spring 2025 (X25) batch, Propolis has already gained early production traction with fast-shipping engineering teams, offering hands-off QA via intelligent browser agent swarms.
