What Lassie does
Lassie, operating under legal entity Go Lassie, Inc. and headquartered in San Francisco, builds autonomous AI agents that automate back-office administrative work for healthcare practices, with primary traction in dental offices. The platform handles insurance billing workflows end-to-end: posting electronic explanations of benefits (EOBs) directly to practice management systems, enrolling practices in EFT/ERA with payers, reconciling insurance payments against bank deposits, following up on claims and handling appeals, and flagging accounts-receivable exceptions for human review. The product integrates with established practice management systems (Dentrix, Open Dental, Eaglesoft) without requiring practices to change existing workflows and operates under HIPAA Business Associate Agreements.
Commercially, Lassie uses a usage/transaction-based revenue model in which "Lassie gets paid when it does work for your office," with pricing customized to each practice's volume and workflows. Go-to-market combines direct demo-based sales targeting practice owners with self-serve PMS onboarding (typical go-live in 1-2 weeks for EFT-enabled offices, up to 8 weeks for paper-check offices). The company reports a footprint of more than 700 practices / 1,000+ dentists across 49 U.S. states, with customer-reported outcomes including a 75% reduction in outstanding accounts receivable, 15+ hours saved per practice per week, and 4x faster insurance payment processing.
Lassie was founded in 2022 by Steijn Pelle and Frédéric Renken and has raised $47 million in total venture funding, including a $35 million Series A in June 2026 led by Andreessen Horowitz (with Night Capital and other founders participating). The Series A added Alex Rampell (a16z partner) to the board and earmarked capital for product development, hiring, and expansion beyond dental into broader medical practice and adjacent small-business verticals. The company currently operates with 11-50 employees.

Revenue model
- Usage-Based Transaction Fees: Lassie operates on a performance-based model where 'Lassie gets paid when it does work for your office.' Once the company understands a practice's volume and workflows, it shows custom pricing. This is effectively a transaction/usage-based model where the company earns fees based on the volume of work performed (EOBs processed, payments posted, claims handled).
