GOLDEN, Colo., — U.S. startup Rendezvous Robotics has raised $20 million in seed funding to develop modular spacecraft that can autonomously assemble, expand and reconfigure themselves in orbit. The technology aims to overcome rocket fairing size limitations and enable the construction of larger space infrastructure.
The oversubscribed funding round was led by MaC Venture Capital and Toyota Ventures, with participation from the University of Michigan Endowment, Astera, Industrious Ventures, Aurelia Foundry, ATX Venture Partners and Mana Ventures. The company previously raised $3 million in pre-seed funding in 2025. The new funding will support spacecraft development, flight demonstrations and engineering team expansion.
How the Technology Works
Rendezvous Robotics is developing one-meter-wide hexagonal spacecraft tiles equipped with sensors, onboard processing, electromagnetic actuators and mechanical latches. The tiles will launch as compact, independent units that fit inside rocket fairings.
Once in orbit, they use electromagnetic forces to maneuver, align and connect without astronauts or external robotic arms. Connected tiles form larger structures with power and data connections, allowing operators to expand solar arrays, antennas and computing systems after launch. Damaged components can also be replaced by sending new tiles instead of launching an entirely new spacecraft.
The technology builds on nearly a decade of research into TESSERAE (Tessellated Electromagnetic Space Structures for the Exploration of Reconfigurable, Adaptive Environments), invented by co-founder and board chair Dr. Ariel Ekblaw at MIT. Earlier versions have been tested aboard Blue Origin’s New Shepard rocket and during two missions to the International Space Station (ISS).
Co-founded by Ekblaw and CEO Joe Landon, Rendezvous Robotics is commercializing the technology, with an initial focus on modular satellites. Landon said the long-term goal includes spacecraft capable of supporting megawatt-scale power generation and large communication platforms that can adapt to changing mission requirements.
Upcoming Testing Schedule
The company has outlined three major demonstrations:
-
November 2026: A parabolic flight campaign will test electromagnetic actuation and tile mobility during short periods of microgravity.
-
December 2026: A payload of 32 fifth-generation TESSERAE tiles is planned to launch to the ISS, where the tiles will autonomously assemble into a three-dimensional structure.
-
April 2028: A free-flying demonstration in low Earth orbit will involve seven independent tiles deploying, autonomously assembling into a spacecraft, separating and reconnecting in a different configuration without external robotic assistance.
The company has reserved a rideshare launch for the 2028 demonstration, which is intended to prove autonomous assembly and reconfiguration in open space.
Rendezvous Robotics will use the new funding to develop larger next-generation tiles, conduct flight demonstrations and expand its engineering team. The company is based in Golden, Colorado, and has shifted its near-term focus from large habitats and space stations toward modular satellites.
