Lassie
Lassie is a San Francisco AI company building an autonomous 'AI healthcare admin worker' for independent medical and dental practices. Its agents log into insurance portals, pull reimbursements, reconcile electronic payments, post entries to practice-management systems, handle appeals and enrollments, and flag exceptions for humans - doing the back-office busywork rather than adding review burden. Founded by Robinhood/Coinbase and Superhuman alumni, Lassie operates in 700+ practices across 49 states and raised a $35M Series A led by Andreessen Horowitz in June 2026.
PARx Solutions
PARx Solutions is a Burlington, Massachusetts healthcare technology and services company that untangles one of medicine's most frustrating chores: prior authorization. Its Prior Authorization Support System (PASS) pairs a secure web portal with a call center of healthcare and reimbursement specialists who handle the paperwork and back-and-forth with health plans on a prescriber's behalf. Because the service is sponsored by drug manufacturers, it is free to physician offices and pharmacies, and it helps patients actually get the medications their doctors prescribed rather than abandoning treatment in the administrative maze.
