Medra is a San Francisco–based biotech startup building an autonomous Physical AI Scientist platform that tightly integrates artificial intelligence with robotic lab automation to transform how scientific experiments are run and analysed. Its system combines “Physical AI,” which uses general-purpose robots to execute protocols on standard lab instruments, with “Scientific AI,” which reasons about data, interprets results, and suggests next steps—all in a continuous feedback loop that accelerates discovery and scales data generation far beyond traditional manual workflows. By capturing rich experimental data at scale and letting AI learn from every outcome, Medra aims to make drug discovery faster, more efficient and more predictive, supporting research from gene editing to therapeutics development and partnering with major biopharma companies to bring this technology into real lab environments.
