# Medra

> Medra builds Physical AI Scientists - robots that run biology experiments end to end. Its platform pairs a reasoning layer that designs and interprets experiments with vision-guided robots that pipette, culture cells, edit genes and log every step, all directed in plain English. Founded by Stanford robotics PhD Michelle Lee, Medra deploys workcells at biopharma partners including Genentech and Addition Therapeutics and is building one of the largest autonomous labs in the United States.

- **Founded:** 2021
- **Headquarters:** San Francisco, California, United States
- **Founders:** Michelle Lee (Founder & CEO)
- **Team size:** ~58 employees
- **Products:** Physical AI Scientist Platform, Physical AI, Scientific AI, Medra Lab 001
- **Notable:** Raised $52M Series A in December 2025, bringing total funding to roughly $63M., Deployed five robotic units at partner sites across the US, including Genentech and Addition Therapeutics., Robots learned to operate 75%+ of standard laboratory instruments without custom hardware.

## Products & services

- **Physical AI Scientist Platform** — An end-to-end system that unifies robotics, AI reasoning and data generation into a continuous experimentation loop - designing, running, interpreting and improving experiments without human intervention.
- **Physical AI** — Vision-guided robotic workcells that execute lab protocols, operate standard instruments (75%+ of common lab equipment), detect and correct errors with computer vision, and log granular data like pipette angle, well depth and reagent timing.
- **Scientific AI** — A reasoning layer that lets scientists program protocols in natural language, reasons across data, images and protocols, and performs closed-loop experimental optimization.
- **Medra Lab 001** — A 38,000-square-foot autonomous laboratory in San Francisco housing hundreds of robots designed to run experiments continuously, including overnight and weekends.
