Ephos, a producer of glass-based photonic chips, has raised an $8.5M seed funding round and will open a research and manufacturing facility in Milan, the world’s first dedicated to producing glass-based quantum photonic circuits. In addition, Ephos has received funding from the EU and NATO’s Defence Innovation Accelerator (DIANA).

The seed round was led by Starlight Ventures, a US venture capital firm specializing in deep tech investments, with participation from Collaborative Fund, Exor Ventures, 2100 Ventures, and Unruly Capital, among others, as well as angel investors Joe Zadeh (former Vice President at Airbnb), and Diego Piacentini (former Senior Vice President at Amazon).
