Lassie: AI That Runs the Doctor's Office Back Office

Lassie is an AI back-office for independent medical and dental practices. Its autonomous agents handle the administrative and insurance work that keeps a practice running but consumes staff time — payer enrollments, EFT reconciliation, payment posting into practice-management systems, claim follow-ups and appeals, weekly claim tracking, and calendar and appointment confirmations. The aim is to run that work largely on its own, so small practices are not buried in paperwork.

Lassie is priced around the work it completes rather than as flat software, aligning cost with output.

Key Features

• Automated payer EFT enrollment
• EFT reconciliation to insurers, patients, and claims
• Payment posting into practice-management systems
• Claim follow-ups and appeals
• Weekly claim tracking
• Calendar management and appointment confirmations

Ideal Use Case

Lassie fits independent medical and dental practices whose small front-office and billing teams are overwhelmed by insurance administration and payment reconciliation. It suits practice owners who want back-office work handled without hiring more administrative staff.

How Lassie differentiates

Lassie automates the specific insurance and billing back-office of independent practices — reportedly posting payments with high autonomy — and charges based on work done rather than seats. It raised a $35M Series A led by Andreessen Horowitz, was founded by operators from Robinhood, Coinbase, and Superhuman, and reports use across hundreds of practices.
