Johannes Galatsanos

Johannes Galatsanos is Co-Founder and CEO of Diffraqtion, a Boston-based quantum imaging startup that has built a quantum camera capable of recovering 95% of photon information lost by conventional sensors - translating to 20x higher resolution and 1,000x faster image processing than any existing optical system. A multilingual MIT and Oxford graduate with Greek-German roots, Galatsanos pivoted from leading AI and data transformation at Novartis to commercializing a decade of DARPA- and NASA-backed quantum photonics research. Diffraqtion won first prize at SLUSH 2025, secured a $4.2M pre-seed round in January 2026, and is targeting satellite launches for space domain awareness and Earth observation by 2028-2029.
