Nat Turner is a highly successful serial entrepreneur turned prolific angel investor, renowned for his deep operational expertise and strategic insights. Based in New York City, Turner co-founded Invite Media, an advertising technology company that was acquired by Google for an impressive $81 million in 2010. Following this success, he co-founded Flatiron Health, a healthcare technology company focused on oncology, which was later acquired by Roche in 2018 for a staggering $1.9 billion.

Leveraging his considerable wealth and experience from these two major exits, Turner has become one of the most active and sought-after angel investors in the United States.

He typically backs startups in sectors where he possesses direct experience, such as AdTech, healthcare technology, enterprise SaaS, and consumer internet. Turner is known for being a hands-on investor, often providing invaluable strategic guidance and leveraging his extensive network to support portfolio companies.

Turner's investment philosophy emphasizes backing exceptional founders with disruptive ideas. He has built a diverse portfolio, participating in over 100 companies, often alongside other prominent angel investors and early-stage venture capital firms. His unique perspective as a founder who has successfully built and exited two major companies makes him a highly attractive partner for nascent startups seeking not just capital, but also mentorship and operational acumen. He is particularly interested in technologies that address significant market inefficiencies or create entirely new categories.
