A former RFIC designer at Raytheon and hardware program manager at Apple (iPhone 8 through 11, early AirTags), he started Bild while earning his MBA at Yale, raised $3M in seed funding months after graduating in 2021, and pivoted the company toward version control and collaboration for mechanical engineering teams - growing revenue tenfold in 2023.
Valentina Ratner
Valentina Ratner is the co-founder and CEO of AllSpice.io, the 'GitHub for hardware' that brings version control, collaboration, and automated design review to the engineers who build PCBs, schematics, and bills of materials. An Argentina-born mechanical engineer turned Amazon PM turned Harvard MS/MBA, she launched AllSpice after watching brilliant teams build complex machines on archaic, file-shuffling workflows. In June 2025 she raised a $15M Series A to take the company's AI design-validation agent out of private beta, with customers spanning Blue Origin, Bose, and Tools for Humanity.
