About

Louis Vichy is a co-founder of OpenRouter, the AI model-routing marketplace Stripe agreed to acquire in August 2026 for a reported $7.5 billion — about three years after he and Alex Atallah, who met on Discord, started it. A largely behind-the-scenes engineer, he previously co-founded Plasmo, the open-source browser-extension framework where he was the top contributor and where the future OpenRouter founders first collaborated, co-founded the robotics cloud platform RosHub, and worked on TurboTax at Intuit. He grew up in Vietnam, studying programming at Hanoi University of Science's High School for Gifted Students before moving to Washington State and earning degrees at Green River College and RIT.

Beyond investing

Founded
Co-founded OpenRouter in early 2023 with Alex Atallah, whom he met on Discord after collaborating on the Plasmo browser-extension framework.

Co-founded RosHub, a cloud platform for managing ROS robotics fleets.
Hobbies
Serial hackathon competitor — 35 hackathons and 16 projects on Devpost — and a onetime Seattle CoderDojo mentor.
More
Built OpenRouter's early 'Sign in with OpenRouter' end-user-pays flow and the routing layer across 60+ providers, on an all-TypeScript stack using Effect. Shares, with co-founders Alex Atallah and Chris Clark, the reported $1.5 billion founder allocation from Stripe's $7.5 billion acquisition of OpenRouter.
