Summary
Sebastien Deletaille is a seasoned tech entrepreneur and CEO with 12+ years of experience building and scaling product-led companies in healthcare and telecom. As co-founder and current CEO of Rosa he’s on a mission to rebuild the patient–provider relationship through a trusted Belgian health app, after previously founding Riaktr (a telecom analytics scale-up) and leading Medispring’s EMR rollout. He combines strategy and hands-on execution—from securing Series A funding and growing teams to registering regulated medical software—and often sits on boards to steer digital and societal impact. Trained as a business engineer at Solvay and a Harvard executive alumnus, he blends business rigor with engineering sensibility and early career consulting at McKinsey. Less obvious: he repeatedly moves between product, policy and community roles (board seats at cancer foundation, startups and academia) to amplify the real-world adoption of tech. Based in Brussels, he’s known for pragmatic leadership that turns complex health and telecom challenges into usable, trust-centered products.
