Relativity Space Raises $35 Million

Relativity today announced the close of a $35 million Series B financing, led by Playground Global, with full participation from existing Series A investors Social Capital, Y Combinator Continuity and Mark Cuban.

Since forming in 2015, Relativity has built what it maintains is the world’s largest metal 3D printer, and it has completed more than 100 rocket engine test fires on a quest to build its own rocket constructed almost entirely of 3D printed parts. Using machine learning in combination with custom software, hardware and proprietary metal alloys, Relativity has cut rocket part count from 100,000 to 1,000 and dramatically reduced labor and timelines by orders of magnitude. According to the company, Relativity’s process disrupts the entire tech stack, including design algorithms, supply chain, inventory management, quality control, and the way raw materials are used in complex aerospace products.

The funding will be used to expand the company’s scalable, automated process for manufacturing and launching rockets from conception to production.
