Bootstrapped growth to 7M patients & 13k doctors in a highly competitive patient engagement software space. I recruited the core team and drove the company to profitability, outcompeting three other SF startups who raised 32x, 120x and 150x more money than DoctorBase.

I recruited the core team, invented the first VoIP SaaS in the industry, and drove the company to the $20M ARR milestone leading both.
