We've watched Heartbeat.ai start as a blip in the medical recruiting industry. They used to make tiny ripples in a very big ocean.

After years of curating their medical recruiting platform, it has expanded its database to nearly 12 million candidates. Bear in mind, there are roughly only 22 million US medical professionals.
