Rendezvous Robotics, a company developing spacecraft that can assemble themselves in orbit, has raised $20 million in an oversubscribed seed funding round.
The investment will support the development of its next-generation spacecraft, upcoming flight demonstrations and team expansion.
The round was co-led by MaC Venture Capital and Toyota Ventures. Other investors included the University of Michigan Endowment, Astera, Industrious Ventures, and existing backers Aurelia Foundry, ATX Venture Partners, and Mana Ventures.
“The vision behind TESSERAE was never simply to connect tiles in space. It was to rethink how we build beyond Earth,” said Dr. Ariel Ekblaw, Co-Founder and Board Chair of Rendezvous Robotics. “For decades, the way we build spacecraft has been shaped by what we can fit inside a rocket. We’re challenging that constraint. What began as an experiment in self-assembly is now becoming a new way to build spacecraft in orbit.”
Rendezvous Robotics is developing modular spacecraft that launch as compact, independent tiles. Once in orbit, the tiles can move, align and connect autonomously to form larger spacecraft. The technology is designed to overcome the size limitations imposed by rocket fairings and allow spacecraft to expand or change configuration after launch.
The company is preparing for a planned 2028 demonstration mission. Seven independently deployed spacecraft tiles will autonomously join to form a spacecraft, separate and assemble again into a different configuration. The mission is scheduled to launch no earlier than April 2028 aboard a rideshare mission.
The technology builds on nearly a decade of research that began with TESSERAE, a modular self-assembly system invented by Dr. Ariel Ekblaw at MIT and further developed through the Aurelia Institute. Earlier versions of the technology have flown aboard Blue Origin’s New Shepard rocket and on two International Space Station missions.
“We’re changing what it means to build a spacecraft,” said Joe Landon, Co-Founder and CEO of Rendezvous Robotics. “Imagine spacecraft with megawatt-scale power generation, enormous communications and sensing apertures, and the ability to expand or reconfigure as mission needs change. Rendezvous is building spacecraft on an entirely different scale, with the ability to add capabilities after launch and take on missions that simply aren’t practical with the way we build spacecraft today. We’ve brought together a world-class engineering team with the experience, ingenuity and technical expertise to make that vision a reality.”
Rendezvous is also conducting ground demonstrations to test autonomous movement, alignment and assembly. A parabolic flight campaign planned for November 2026 will further test the technology in microgravity.
Separately, a final demonstration of fifth-generation TESSERAE technology is scheduled for December 2026 aboard the International Space Station. The experiment will test the autonomous assembly of 32 tiles into a three-dimensional structure.
Headquartered in Golden, Colorado, Rendezvous Robotics aims to make spacecraft more flexible and capable for commercial, civil, and national security missions.
