Prototyping.io
Prototyping.io is a San Francisco startup (YC Spring 2026) building an AI-native manufacturing platform that turns CAD designs into finished mechanical parts in as little as one day. It automates the traditionally manual path from design to production - DFM analysis, sourcing, process planning, machine programming and setups - so hardware teams can iterate in days instead of weeks. The company serves customers from early-stage startups to multi-billion-dollar enterprises across robotics, AI infrastructure, energy, automotive and defense.
Relativity Space
Relativity Space is an American aerospace company building rockets in a radically different way - by 3D printing the bulk of each vehicle with its proprietary Stargate metal printers and autonomous robotics. Founded in 2015, it became the first company to launch a largely 3D-printed rocket (Terran 1) in 2023, and is now focused on Terran R, a medium-to-heavy-lift, fully reusable launch vehicle aimed at the commercial and government markets. Under CEO Eric Schmidt, who took the helm in 2025, the company is also exploring orbital infrastructure for AI and high-performance computing.
