§ Private Profile · Palo Alto, CA, USA
Theator is a technology company.
Theator develops a surgical intelligence platform that leverages artificial intelligence and computer vision to meticulously analyze surgical video data. The core product automatically captures, structures, and interprets intraoperative activities, extracting actionable insights to enhance surgical performance. By processing this rich dataset, the platform identifies optimal techniques and areas for improvement, providing objective feedback to surgeons.
The company was co-founded by Dr. Tamir Wolf and Dotan Asselmann following Dr. Wolf's personal experience observing significant variability in surgical outcomes for a routine procedure. This insight, rooted in the limitations of traditional subjective, apprenticeship-based surgical training, fueled the vision to create a data-driven approach to surgical education and improvement. Dr. Wolf, a physician, recognized the need to augment surgeon capabilities and standardize best practices across operating rooms.
Surgeons and medical institutions utilize Theator's platform to refine their skills and elevate the quality of patient care. The company’s long-term vision is to illuminate the complexities of the operating room, identify and disseminate surgical best practices globally, and ultimately reimagine surgery to save millions of lives by ensuring consistent, high-quality outcomes.
Theator has raised $70.0M across 5 funding rounds.

# Theator: Surgical Intelligence Pioneer
Theator is an AI-powered surgical intelligence platform that uses computer vision and large vision-language models to automatically capture, analyze, and structure surgical video data in real time[1][4]. The company serves hospitals and healthcare providers, addressing a critical gap in modern surgery: while most operating rooms now have cameras recording procedures, surgeries are rarely captured, stored, or systematically analyzed to improve outcomes[3].
The core problem Theator solves is surgical variability—the significant differences in outcomes not only across regions but even within the same hospital[6]. By transforming raw surgical video into actionable, data-driven insights, Theator enables hospitals to improve surgical quality, accelerate surgeon training, enhance operational efficiency, and ultimately deliver more consistent patient care[5]. The company was founded in 2018 and is based in Palo Alto, California, with an R&D site in Tel Aviv[3].
Theator emerged from a clear insight: surgical care is "highly variable, siloed, and not transparent," with outcomes often determined by geography rather than clinical best practices[7]. Co-founder and Chief Technology Officer Dotan Asselmann drew inspiration from advances in autonomous vehicles, recognizing that AI could help surgeons make better decisions by analyzing thousands of procedures—far more experience than any individual surgeon could accumulate[3].
The company's early breakthrough came through collaborations with prestigious institutions like the University of Miami and Mayo Clinic, where Theator tested an algorithm to automatically generate operative reports, documents surgeons traditionally write manually[1]. This validation from leading medical centers demonstrated the platform's clinical viability and helped establish Theator as a credible player in surgical AI.
Theator is riding the convergence of three powerful trends: the maturation of computer vision and large vision-language models, the widespread adoption of surgical video recording in operating rooms, and growing pressure on healthcare systems to improve quality while controlling costs. The timing is critical—most ORs now have cameras, but the infrastructure to systematically analyze that data has been absent until now[3].
The company's approach mirrors the autonomous vehicle industry's philosophy: use AI to learn from massive datasets to prevent errors before they occur[3]. In surgery, this means surfacing best practices from real-world performance and enabling surgeons to meet performance indicators for specific tasks[5]. Theator is helping establish surgical intelligence as a new category—a layer of understanding that transforms unstructured video into structured, actionable clinical data.
By connecting surgical video to patient outcomes at scale, Theator is influencing how hospitals think about quality improvement, training, and operational transparency. The platform's ability to generate real-time AI-powered annotations during live procedures (as demonstrated in a live-streamed robotic urology surgery) signals a shift toward AI-assisted surgery as standard practice[5].
Theator is positioned at the intersection of AI maturation and healthcare's urgent need for quality standardization. The company's vision extends beyond retrospective analysis to real-time surgical decision support and AI-driven procedures[4]—a future where surgeons receive live guidance powered by insights from thousands of procedures worldwide.
Key trends shaping Theator's trajectory include the healthcare industry's accelerating digital transformation, regulatory pressure to demonstrate quality metrics, and growing surgeon acceptance of AI as a collaborative tool rather than a replacement. As the company scales across more surgical specialties and integrates deeper into hospital workflows, it will likely influence how surgical training, credentialing, and quality assurance are conducted globally.
The broader implication: Theator is helping democratize surgical expertise, allowing hospitals in any geography to access the collective knowledge embedded in thousands of procedures. In a field where "where you live can determine if you live," that shift toward transparency and consistency represents a meaningful step toward equitable surgical care[7].
