Satlyt raises $8M seed to run AI onboard third-party satellites

Satlyt, a software company based in Sunnyvale, California, with its Africa headquarters in Nairobi, announced an $8 million seed round on 1 October 2026. Houston-based non sibi ventures led it. Participants include several Africa-focused and US funds, among them TLCOM, Antler and Launch Africa Ventures, as well as existing investors.

The money will fund product development, larger engineering and delivery teams, and deployments on more spacecraft run by other companies. Satlyt's software processes images, measurements and system logs onboard, cutting the data sent to Earth. An earlier deployment ran a Gemma model onboard a satellite to analyse system logs.

The next deployment, on SpaceX's Transporter-18 mission, is planned to run research software from NASA-funded work with the University of Houston and a commercial imagery-processing application on one spacecraft. Coordinating computing across several spacecraft remains a longer-term aim.

Why it matters: Onboard processing could shorten the wait for usable Earth observation results and ease downlink limits. A Nairobi-based team with agreements with the Kenya Space Agency and Angola's GGPEN shows African engineering involvement in orbital computing.
