Proximie vs Theator (2026)
Proximie and Theator both build on surgical video, and CB Insights lists Proximie among Theator's closest competitors. Proximie started with live collaboration; Theator started with analysis of the operative feed. Proximie's Surgical Suite lets remote experts, trainees and device representatives join a live procedure with video, audio and annotation, and records a case library for training. Its Intelligence Suite adds computer vision event detection, finish time forecasts, daily huddle dashboards and a two way EHR loop over HL7 and FHIR, and the company publishes its business associate agreement and lets customers pick an AWS region. Theator turns the laparoscopic or robotic camera feed into a structured record of steps, instruments, safety milestones and complications, then writes the operative report into Epic or Oracle Health through Surgery-to-Text and feeds quality benchmarking and teaching. A Mayo Clinic study measured its reports against expert video review. Proximie suits a hospital that wants remote proctoring, device support and operating room flow; Theator suits one that wants documentation and technique analytics built from the procedure video.
- Live remote participation in procedures for experts, trainees and device representatives, with annotation.
- A published business associate agreement that binds subcontractors, plus a published data processing agreement.
- Customer choice of AWS data region in the US, EU, Singapore or Australia.
- An SDK and a Deploy AI route for device companies building on real procedure data.
- Billing ready operative reports written from video and signed by the surgeon inside the EHR.
- Critical view of safety tracking, used in a published quality initiative where monthly adoption rose from 33 to 76 percent.
- Report error rates published from a 158 case Mayo Clinic study.
- Reports and certificates for SOC 2 Type 2, HITRUST and ISO/IEC 27001 offered through its trust center.

Theator analyzes the video from existing laparoscopic and robotic cameras with a proprietary model trained on more than 600,000 procedures. Surgeons get operative reports drafted in Epic or Oracle Health, and departments get benchmarking, safety milestone tracking, a searchable teaching library and research data from the same record.

Questions buyers ask
Can each one bring a remote expert into the case?
Proximie is built for it: a remote surgeon, trainee or device representative can join live with video, audio and on screen annotation. Theator centers on analysis, though one of its case studies describes a surgeon livestreaming an annotated case through its app. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified October 12, 2026. No vendor pays for placement.
How does each connect to the EHR?
Proximie runs a two way loop with any EHR over HL7 and FHIR without naming a vendor or live site. Theator delivers reports into Epic and Oracle Health, with two Epic Connection Hub listings and an Oracle announcement describing the Oracle Health connection. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified October 12, 2026. No vendor pays for placement.
What happens to patient video?
Both de identify at the source. Proximie's published agreements let it use de identified data to train its algorithms, and it states no retention period. Theator removes identifiers and out of body frames at capture, says new procedures improve its model, and keeps retention terms in its trust center. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified October 12, 2026. No vendor pays for placement.
