Lassie develops autonomous software agents that perform administrative tasks for small businesses, with an initial focus on doctors' offices. Founded by former product managers from Robinhood, Coinbase, and Superhuman, the company automates workflows such as pulling reimbursements from insurance portals, reconciling records, updating systems of record, and verifying bank deposits. Lassie currently serves more than 700 practices across 49 states and reports delivering over 250,000 hours of labor to business owners each year, with individual customers citing savings of 100+ hours per month. Financially, the company has raised $47 million to date, including a $35 million Series A led by Andreessen Horowitz. Lassie plans to use the new capital to accelerate growth and adoption, and has added Alex Rampell to its board and other advisors to support scaling.
