Rendezvous Robotics has raised $20 million to develop spacecraft that can assemble and change shape in orbit, rather than launch as one finished structure.
The Golden, Colorado startup’s oversubscribed seed round was led by MaC Venture Capital and Toyota Ventures, with participation from the University of Michigan Endowment, Astera and Industrious Ventures.
Its technology traces back to TESSERAE, a modular assembly project developed by co-founder Ariel Ekblaw at MIT. Earlier versions flew on Blue Origin’s New Shepard and took part in two missions to the International Space Station.
A further ISS experiment scheduled for December 2026 will test 32 tiles forming a three-dimensional structure. The bigger milestone comes no earlier than April 2028: seven independently deployed tiles are expected to assemble into one spacecraft, separate, and reconnect in a different configuration.
Rendezvous will use the money for spacecraft development, flight tests and hiring. The real test is whether independent tiles can reliably assemble in open orbit, without an external robot holding the pieces together.
