Like so many people with busy 9-to-5s, high school teacher Suzanne Grinberg has a scheduling problem: By the time she has a free moment in her day to call her doctor to make an appointment, the doctor’s office is already closed.
So, when she recently called her dermatologist before business hours, Grinberg expected to leave a voicemail—but instead got a pleasant surprise. “At 5:30 AM, when I was putting on my makeup to go to work, I was able to make my appointment,” she said.
Grinberg’s dermatologist had started using a voice AI system called Assort Health, a startup building specialty-specific agents for healthcare. The company was founded in 2023 by Jeff Liu and Jon Wang, who together spent two years getting to know the healthcare system before the startup picked up steam.
“What’s really interesting about our space is that voice AI and LLMs have actually been around for a while,” said Liu, who is the co-CEO. “But healthcare is so complicated. They have binders, spreadsheets full of these really complicated rules, and that’s prevented automation from helping providers—despite them really needing help.”
Assort, which to date has collected approximately 42 million patient interactions on its platform, raised its $22 million Series A in April, with Term Sheet breaking the news. They’re now back, just a few months later: Assort has raised a $76 million Series B, led by Lightspeed, Fortune can exclusively report. First Round and Chemistry, which led the Series A, returned as investors for this round and were joined by Felicis, A*, Liquid 2 Ventures, and Quiet. This brings Assort’s total capital raised to date to $102 million, and to one doctor, the tech solves a key business problem.
