Optimized medical device purchasing for independent providers

Floracene shows independent surgery centers the best-priced equivalent implant for every procedure based on their manufacturer contracts. Every orthopedic surgeon we've talked to says the same thing: 90%+ of expensive implants they use are clinically interchangeable, but the choice comes down to habit, brand comfort, or the device rep. US surgery centers spend ~$7B a year on implants, and in orthopedic and spine cases the implant alone runs ~40-60% of the total cost of the procedure. Roughly ~20-30% of that spend is recoverable by switching to a clinically-equivalent device. Instead of defaulting to the implant they trained on, a surgeon sees the 3+ equivalent options side by side and switches to the one that protects the case's margin. Asaph and Jonah met on the hospitals team at Palantir two years ago, and have each spent the last four years in the plumbing of US healthcare: claims, eligibility, and payor contracting. Asaph was an early PM at Garner. Jonah was a founding engineer at Metriport (YC S22) after starting his own fax-automation startup for fertility clinics. At a big hospital the surgeon picks the implant but isn't spending their own money, so price doesn't impact the decision. At an independent surgery center the physicians own the economics, so a cheaper equivalent goes straight to their bottom line. They have every incentive to switch. They just don't have the information or the tooling.
