In 2020, Stein Pella was a patient at Dr. Kwan’s dental practice in Silicon Valley. Dr. Kwan was the number one rated dentist on Yelp, but he was spending 200 hours a month on paperwork—winning claims by hand, processing payments, reconciling insurance. Pella, who had moved from Amsterdam to start a company, asked to see how the business ran. He never forgot what he saw. That moment became Lassie, a company that builds AI agents to automate administrative work for small healthcare practices, starting with dentists.

The problem software never solved

Alex Rampell, a16z general partner, frames Lassie’s opportunity by rethinking what software has historically done. For decades, software took paper filing cabinets and made them digital—Sabre for airline reservations, PeopleSoft for HR, QuickBooks for accounting. But people still had to do the work. The filing cabinet just became a database. “Nothing really got more efficient,” Rampell says, exaggerating only slightly. The real shift is that AI can now edit the filing cabinet—perform the work, not just store the information. The market for software that does labor is orders of magnitude larger than the market for software that stores data.

Show Notes

Alex Rampell and Olivia Moore speak with Lassie cofounders Steijn Pelle and Frédéric Renken about bringing AI to one of the most overlooked parts of the economy: small businesses.

Inspired by time spent working inside dental practices, Pelle and Renken set out to automate the administrative work that keeps healthcare providers away from patients. They discuss how AI agents are changing billing, insurance claims, patient payments, and other operational workflows, allowing practices to spend less time on paperwork and more time delivering care.

The conversation explores AI agents, software that performs work rather than simply storing information, onboarding AI into real-world businesses, and why healthcare administration offers one of the biggest opportunities for automation. Along the way, they discuss product design, go-to-market strategy, and what it takes to build AI systems that operate reliably in complex business environments.
