Many startups have taken on the challenge of helping us find any doctor. But few companies are dealing with the complicated problem of connecting patients with the best doctor. San Francisco-based startup Amino Health aims to do just that. The company has developed a tool to connect patients with a local provider who is their "best match." The company is analyzing a massive volume of data to rank doctors based on how many patients they've treated with a particular symptom, ailment, or condition. I met with Amino Health's CEO, David Vivero, late last week, just a few months after the launch of the company's initial product, its doctor-finder tool.
