Not a start-up but a non-profit.

I'm the vice chair at Libre Space Foundation (https://libre.space).We create open-source space technologies. Some of our projects:

- SatNOGS rotator: an azimuth/elevation rotator for directional antennas.

- UPSat: 1st cubesat build under open source hardware licenses that got in orbit (design deprecated)

- SatNOGS-COMM: next gen communications module for CubeSats

- QUBIK: even smaller pico-satellites that got also in orbit in Oct 22

- PICOBUS: pico-satellite deployer also in orbit Oct 22

- SIDLOC: a spacecraft location and identification beacon protocol and hardware, will be on the last stage of the Ariane 6 inaugural launch.
