Ellen DaSilva is the Founder and CEO of Summer Health, the pediatric healthcare company that served 30,000+ families before being acquired by Doctronic in 2026. Earlier, she was employee #8 at Hims & Hers and worked at Twitter during its hyper growth years. She is an active angel investor and Sequoia Scout, and earned her MBA with Distinction from Harvard Business School.

In this conversation, Ellen joins Vidit to unpack the ambition behind her extraordinary career, the leap from Wall Street to scaling Twitter during its hyper gowth years, why she nearly became a Hims competitor before joining as employee #8, and what happened when she finally took the founder leap with Summer Health.

They also explore how consumer software has changed, what makes great companies feel “inevitable”, why Ellen is “incapable of turning off founder mode”, and the philosophy behind living life on “maximum mode” and lots more. 

Please enjoy exploring your curiosity.
