Lightfoundry is a space-focused company providing reliable solar power solutions for satellite missions, with a strong emphasis on availability and timely delivery. Founded in Estonia in 2025 by engineers with more than 20 years of combined spaceflight heritage, Lightfoundry builds on experience from over 25 successfully launched satellites by its founders, from CubeSats to microsatellites.

Through years of hands-on involvement in spacecraft development, testing,  launch, and operations, we have seen first-hand how critical solar cells are to mission success — and how delays in procurement can directly impact schedules, costs, and program risk. Today, the space sector faces increasing constraints in accessing qualified solar cells when they are needed most. 

Lightfoundry addresses this challenge by providing ready-to-supply solar power products, held in stock and supported by fast delivery. By combining  deep mission experience with a pragmatic approach to supply, we help spacecraft developers secure the power solutions they need, when they need them.
