Hardware engineering is mostly document-based. A typical satellite might be described in several hundred thousand PDF documents, spreadsheets, simulation files and more; all potentially inconsistent between each other. This can lead to costly mistakes. NASA lost a $125 million Mars orbiter because one engineering team used metric units while another used English units, for instance.

Germany-HQ’d Valispace, which also has offices in Portugal, dubs itself as “Github for hardware”. In other words, it’s a collaboration platform for engineers, allowing them to develop better satellites, planes, rockets, nuclear fusion reactors, cars and medical devices, you name it. It’s a browser-based application, which stores engineering data and lets the users interconnect them through formulas. This means that when one value is changed, all other
