Aetherflux is building the infrastructure to power and connect the orbital economy. Our satellites operate in Low Earth Orbit to collect sunlight and enable a new class of capabilities-from transmitting energy via infrared lasers (space-to-earth and space-to-space), to powering on-orbit compute, to delivering secure, high-bandwidth optical data. By rethinking how energy and data are generated and distributed in space, we're unlocking entirely new ways to operate both in orbit and on Earth. Founded in 2024 by Baiju Bhatt (co-founder of Robinhood), Aetherflux is backed by leading investors and built by a team from top aerospace and defense organizations. We're moving quickly to solve complex technical challenges and build a new category of space infrastructure.
