Pelago is a virtual clinic for substance use management, delivering physician-led, evidence-based care for tobacco, alcohol, opioid and other substance use. Founded in 2017 as Quit Genius by three Imperial College London physicians, the company combines cognitive behavioral therapy, medication-assisted treatment and at-home monitoring tools into a program sold to employers, health plans and pharmacy benefit managers. Pelago says it has supported more than 750,000 members and validates its approach with 13 peer-reviewed studies.

Yusuf Sherwani is a London-born, New York-based medical doctor turned founder who runs Pelago (formerly Quit Genius), the digital clinic he co-founded in 2017 with two medical school classmates, Maroof Ahmed and Sarim Siddiqui. A Y Combinator alumnus and Forbes 30 Under 30 honoree, he has raised more than $150 million from investors including Atomico, Kinnevik and Octopus Ventures to scale technology-driven, evidence-based care. Trained at Imperial College London with an MD and a BSc in management, he co-authored roughly a dozen peer-reviewed studies before pivoting fully into building. He is also an active angel investor backing early-stage founders and writes about healthcare, technology and finance on his personal blog.
