Coral raised $12.5M for AI back-office automation in healthcare

New York-based startup Coral has closed its Series A round at $12.5 million. The funding will go toward scaling an AI platform that takes on the most routine and resource-intensive part of medical administrative work.

The system reads handwritten fax forms, processes prior authorization requests for procedures, and registers new patients — all of this takes five minutes. Without the involvement of a doctor or administrator. This sounds like a marketing slogan, but there's a concrete technical task behind it.

American clinics still massively rely on fax machines: insurance companies require paper forms for prior authorization — advance approval for expensive procedures. These forms are often filled out by hand, arrive illegible, and require manual transcription. This is where hours of lost working time happen every day.

Coral has trained its AI to recognize these forms and extract structured data from them. Then the system itself sends a request to the insurance company, tracks its status, and records the response in the patient's medical record. In parallel, the same infrastructure processes intake — the initial appointment of a new patient, collecting medical history and insurance information.

The entire cycle, which previously took an administrator 30-60 minutes, is closed automatically. The key feature of the product is that it doesn't require clinics to change their established processes. Faxes, phone calls, EHR systems remain in place.

This is a principled decision. Most healthcare startups crash into the implementation wall precisely because they require staff retraining and IT infrastructure overhaul. Coral bet on a different approach: the system works on top of existing chaos, without requiring it to be dismantled first.

This positioning is exactly what allowed the startup to quickly build its customer base. Less than a year after launch, Coral is already generating several million dollars in revenue. The specific amount is not disclosed, but for an early-stage company this is a strong signal of product-market fit.

By the end of 2026, the company plans to grow four times. Administrative burden is one of the main sources of burnout among medical professionals in the US. According to the American Medical Association, doctors spend as much time on documentation as they do seeing patients.

Clinics lose billions of dollars annually to manual data entry, phone calls for insurance approvals, and paper bureaucracy. Prior authorization is a classic example: the process is standardized, highly competitive, but poorly automated due to dependence on outdated data transmission formats. The $12.

5 million that Coral attracted will be directed toward expanding the team, product development, and entry into new medical specialties. The company has not yet disclosed the names of the round's investors. Coral's story is a working formula for healthcare startups: don't rewrite medicine from scratch, but solve the most painful problem with precision — administrative chaos.

The principle of "don't change provider processes" lowers the implementation barrier to a minimum and allows for scaling without months-long negotiations with clinic IT departments. If the 4x growth materializes, by year's end Coral will become one of the notable players in medical AI back-office automation.
