Sebastian Coates

Sebastian Coates is the CEO and co-founder of Tellescope, a HIPAA-compliant, API-first patient communication and CRM platform used by more than 150 digital health organizations. A Tufts computer science and mathematics graduate who once wrote software for the Apple Watch and prototyped blockchain systems for clinical trials at Vertex Pharmaceuticals, he started Tellescope in 2020 with co-founder Derek Strauss to give telehealth companies a developer-friendly tech stack for managing patients across SMS, email, voice, and secure messaging. Notably, he has kept the company lean and profitable rather than chasing oversized venture rounds.
