Lassie has successfully raised $47 million in a Series A funding round led by a16z to develop AI solutions specifically designed to run small businesses, beginning with dental practices. Cofounders Steijn Pelle and Frédéric Renken dedicated months to working inside dental offices to understand the workflow, identifying significant administrative challenges that consume valuable time for practitioners. With over 700 dental practices already utilizing its services, Lassie’s AI autonomously provides around 30 hours of labor per month, addressing key pain points in the industry, which is increasingly turning to AI to streamline operations rather than augment them.
