Mark Ruiz

Kaliber is a medical AI company that is shaping the future of surgical care. On the journey to create the machine brain for autonomous surgery we are creating AI solutions to enhance and augment the surgeon’s skill. Our solutions reduce procedural time and deliver consistency. Ultimately, our solutions will improve surgical outcomes and democratize surgery by reducing cost and impacting lives. 

Our AI solutions interpret endoscopic video feeds and recognize anatomical / pathological structures. In addition, Kaliber’s software allows surgeons to obtain precise point to point measurements as well as calculate the area and volume of structures intraoperatively using generic probes. Our AI algorithms provide guidance during a surgical procedure based on the techniques employed by expert surgeons and supported by validated metrics.

Kaliber AI bridges preoperative planning, surgical performance, and postoperative communication with patients and their families. We also help surgeons achieve better patient satisfaction - Kaliber AI generates surgical excerpts, assists them communicating their skills and helping patients to understand the surgery they have undergone.

Kaliber is headquartered in San Francisco, with research offices in Finland and India. The creation of AI solutions is directed by top US orthopedic physicians serving on the Kaliber Surgery Advisory Board. 

Kaliber is solving the most challenging problems in surgery today in an effort to democratize surgery and ensure superior outcomes for surgical patients tomorrow.
