Kepler sells optical data-relay connectivity from its satellite network to commercial and government customers, including hosted-payload users.
Darker bar: ahead of the other company on that measure.
Kepler Communications is a Canadian operator of an optical data-relay network (33 satellites operating, its first ten optical-relay satellites launched January 2026) that adds on-orbit compute and hosted-payload capacity, the relay layer every LEO operator may rent. It became Neutron's first named commercial customer (August 2026, a dedicated Rocket Lab launch no earlier than 2028), choosing dedicated launch because the live network needs orbital precision rideshare can't give. Revenue is estimated at 10-100m (~$500M raised class).

Starcloud develops and operates orbital data centers that host GPUs and provide cloud, edge-compute, and AI workloads in space. Its planned constellation is explicitly designed as in-space computing infrastructure.
Darker bar: ahead of the other company on that measure.
Starcloud is a US orbital-compute company (ex-Lumen Orbit, 15 staff) that became the fastest unicorn in Y Combinator history (a $1.1B valuation in March 2026), whose Starcloud-1 (launched November 2025) carried the first NVIDIA H100 GPU in space and trained the first LLM in space (December 2025). Starcloud-2 (October 2026) carries multiple H100s, and it filed with the FCC in February 2026 for an 88,000-satellite compute constellation, making it the flag-carrier of the orbital-compute theme. It is pre-revenue, and a recorded skeptic point is Varda's estimate that orbital compute costs ~3x per watt versus terrestrial.
