Lassie enables doctors to focus on patients, not paperwork.
The average practice spends around 200 hours a month running itself. We have seen firsthand how the administrative burden is quietly breaking independent healthcare.
Doctors work late into the night so that they can get through all of their paperwork by hand. Nobody taught them how to submit a claim, bill a patient, or reconcile insurance payments.
Our goal is to enable these businesses to run themselves.
Lassie works autonomously, around the clock, reading insurance claims, reconciling payments, handling denials and appeals.
Over 700 practices across 49 states trust Lassie to run their operations. In the past year alone, we have saved more than 250,000 hours of labor, time redirected entirely to patient care.

👋 Nice to meet you!
I enjoy building products that people love. Currently building AI that runs small businesses, starting with the doctor's office.
Previously, I was one of the first product managers at Robinhood (25 million users), Coinbase (100 million users), and HealthTap.
I helped to expand Robinhood's user base from 6 million to 10 million, primarily through building out the "invite your friends" referral program, which accounted for over 80% of new users at the time of IPO. I also started Robinhood Learn (learn.robinhood.com).
I'm an avid runner. If you happen to see a blur speeding along the trails near San Francisco, chances are, it's me.
