Winston Weinberg is a former lawyer who moved into the tech world and co-founded Harvey AI, one of the fastest growing startups in the world of legal technology.
He left a promising law career after a year to build software that uses artificial intelligence to support lawyers in drafting documents, researching complex issues and speeding up work that once took hours. His leap into technology has made him one of the youngest influential founders in the AI industry.
Early Life & Education
Winston Weinberg grew up in the United States. Like many children interested in solving big problems, he pursued a strong academic path that bridged liberal arts and legal expertise.
He earned his Bachelor’s degree at Kenyon College, where he built strong skills in critical thinking and clear communication. Later, he completed his Juris Doctor degree at the University of Southern California Gould School of Law, one of the most respected law schools in the country.
This legal education later became an important foundation for his startup journey, as it helped him understand legal work deeply and see how technology could improve and modernize it.
Career Start & Key Breakthrough
Winston started his professional journey as a lawyer. He worked as an associate at O’Melveny and Myers LLP, where he handled matters related to securities and antitrust law. His legal career was stable and respected, yet Winston noticed a growing shift that many legal professionals had not fully seen at that time.
He understood that artificial intelligence had the potential to change daily legal work in a meaningful way.
The turning point came in 2022, when he joined forces with Gabriel (Gabe) Pereyra, a researcher who had worked at Google DeepMind. Together, they left their regular career paths with a bold idea: build powerful tools that help lawyers complete routine tasks faster and smarter by using artificial intelligence.
This decision became their key breakthrough. They co-founded Harvey AI, designed to create generative AI assistants for the legal world.
