Mithril Technologies

Mithril Technologies, Inc. is a Somerville, Massachusetts-based space technology startup developing dynamically reshapable mesh reflector antennas for satellites. The company's core innovation is an electrostatic actuation technique applied to a heritage deployable mesh reflector design, allowing the reflector's surface shape to be actively reconfigured on-orbit — something conventional satellite antennas cannot do.

This reconfigurability is aimed at solving a long-standing tradeoff in satellite communications and remote sensing: the need to choose between wide coverage range and fine reconfigurability. Mithril's technology is designed to let a single antenna serve multiple purposes across its operational life — for example, adapting a GEO satellite's radar or communications beam pattern in near real time to respond to changing mission needs, evade signal jamming, or track fast-moving weather events such as hurricanes with greater precision than fixed-shape reflectors allow.

The company was co-founded by CEO Scarlett Koller, a space systems engineer with integration and test experience at SpaceX and NASA JPL. Mithril's core technology originated in the lab of Professor Zack Cordero at MIT's Aerospace Materials & Structures Lab, who now serves on the company's Board of Advisors. Mithril has built a small, technically deep team spanning SpaceX, NASA JPL, Analog Devices, ASML, Shield AI, Astranis Space Technologies, and the U.S. Space Force.

As of late 2025, Mithril was operating out of a lab space at Greentown Labs in Somerville, actively prototyping and iterating on a 'Mark 2' reflector prototype, buying down technical risk on mechanical design and dish-shaping ahead of a planned on-orbit demonstrator. The company's pitch on adaptive RF sensors for upper-orbit space was deemed Awardable by the DARPA ERIS Marketplace in September 2025.
