Aimbient (OR Black Box)

What is Aimbient and who sells it?

Surgeon Teodor Grantcharov founded the company in 2014. It is based in Toronto, with an office in New York. The company renamed itself from Surgical Safety Technologies to Aimbient, and the Black Box Platform became the Aimbient Suite.

A $15M Series A, led by U.S. Venture Partners and Santé Ventures, was announced on 4 May 2023 (FinSMEs). Tracxn lists a Series B dated 17 February 2026 and $33.2M in total funding. The company is privately held.

What does it do?

The vendor calls it "the first ambient AI platform built for procedural medicine" and says it "captures every case, understands it with purpose-built AI, and turns it into intelligence your teams use, before, during, and after every case." Capture is hands-free and covers the full case, and AI models read the room context and clinical data.

The vendor lists five uses: operational efficiency such as room and case coordination, quality and safety, surgical education, compliance and trauma video review. Trauma review combines synchronized video, audio, vitals and EHR context. Dashboards benchmark measures like block utilization against the Aimbient network. The About page states the principle as "clinical game tape, never a referee," under a non-punitive covenant.

The vendor's scale claims are 45% or more of U.S. News top hospitals in its network, more than 90 peer-reviewed publications and 14M+ hours captured.

What backs the claims?

Grantcharov's research group has published on the approach. The American Hospital Association's innovation center published a neutral overview in 2023 on how recording systems in the operating room support safety. A news profile hosted on the vendor's own site describes the OR Black Box concept.

No 510(k) is listed for OR Black Box, which is presented as an analytics platform and not a medical device. HIPAA, SOC 2 and HITRUST are not stated on the vendor's pages.

What does it cost?

Pricing is by briefing request through the vendor's site.

The verdict

Aimbient suits a hospital that wants recording in its operating rooms and has an answer ready for how staff, patients and legal will treat the footage. The vendor describes a non-punitive covenant, which is a stated policy. A department that needs a cleared device, a published security attestation or independent outcome data should look at other options.
