LEM Surgical is a Bern-based startup developing a next-generation robotic surgery platform, with its primary focus on the development and commercialization of the Dynamis Robotic Surgical System, its flagship hard tissue robotic system for spine surgery. The company was founded in June 2021 by a team that includes Stefan Weber, CEO of CAScination AG, Andreas Raabe, Director of Neurosurgery at Inselspital Bern, Marco Matulic, CTO of CAScination AG, Simon Michel, CEO of Ypsomed Group, and Yossi Bar, previously Director of R&D at Mazor Robotics before its acquisition by Medtronic. In April 2025, the Dynamis Robotic Surgical System received US FDA clearance (K243326). When Guided Solutions was engaged, the company needed to appoint its founding CEO to lead the build from the ground up.
Challenge
LEM Surgical needed a founding CEO with hands-on spinal robotics build experience at an executive level, not someone adjacent to the space, but someone who had done it. That profile existed in only a handful of people globally. The role also required relocation to Bern, Switzerland, which eliminated most candidates before the conversation even started. There was no open talent pool to search, no shortlist to pull from, and no margin for a mis-hire. For early-stage MedTech companies facing a similar situation, whether hiring a founding CEO, a first commercial lead, or a regulatory head with no obvious successor pool, the challenge is the same: the right person is rarely visible, rarely looking, and rarely reachable through conventional channels.
Solution
Guided Solutions ran a genuinely global search, mapping leadership across spinal, orthopedic, and soft-tissue robotics. Rather than working from a database of active candidates, the team built a picture of the entire relevant leadership universe and engaged high-caliber passive candidates who were not on the open market. Every approach was made under strict confidentiality, protecting LEM Surgical's competitive position throughout the process. For MedTech startups conducting executive searches in specialist or emerging technology segments, passive candidate engagement is not a nice-to-have. It is the only way to access the people who are actually qualified. The candidates who will move the business forward are almost never the ones applying. They are the ones who need to be found, approached with credibility, and given a compelling reason to listen.
Result
The search closed in 12 weeks with the appointment of Yossi Bar as founding CEO. Yossi had recently exited Mazor Robotics, the company that defined the spine robotics category before its acquisition by Medtronic, bringing exactly the build experience the brief required. He relocated to Switzerland and LEM Surgical was stood up around the appointment. The company later closed an oversubscribed CHF 22M Series B from Swiss and US investors, and the Dynamis Robotic Surgical System has since received US FDA clearance.
For MedTech founders and investors evaluating executive search for early-stage leadership hires, the LEM Surgical case illustrates the compounding value of getting the first appointment right. The right founding CEO does not just fill a seat. They attract capital, build credibility with investors, and create the conditions for everything that follows.
