Inside every satellite runs a heavy bundle of cables carrying data between its instruments and computers. According to the EU project Oledcomm won, those signal harnesses can account for up to 10% of a satellite's dry mass. Oledcomm, a company from the Paris-Saclay area best known for LiFi, wireless networking with light instead of radio, proposed to replace some of them with short optical links.
The European Innovation Council paid €2.5 million towards the €3.94 million SATELLIFE project. Within fifteen months Oledcomm's module had flown on a nanosatellite, on OneWeb satellites and inside the fairing of Ariane 6 on its first flight. It is a strong technical record. The commercial one is harder to judge, because the company has not published its accounts since 2017.

What Oledcomm Does Today
Oledcomm sells LiFi products on the ground and, since SATELLIFE, for space. In space it has moved from links inside a spacecraft to links between spacecraft. With the French space agency CNES it is developing LUCI, an ultra-compact inter-satellite terminal that the company says is designed for optical links of up to 7,800 kilometres.
In April 2023 the trade site VIPress reported that Oledcomm was preparing a fundraising of about €10 million, with the European Union expected to take one third. We found no public announcement that the round closed, of its final size, or that the EIC Fund's investment was completed.
The Technology: Data by Infrared Light
LiFi carries data by modulating light, which a photodetector reads back. According to ESA, it "may offer greater security, higher bandwidth, lower cost and power consumption" than Wi-Fi. Inside a spacecraft, short line-of-sight optical links could replace some cables, cutting weight and simplifying assembly and testing, which is the case SATELLIFE set out to prove.
"The LIFI experiment onboard Ariane 6 will be a world first as it will be the first time that Li-Fi technology has been embedded in a space launcher."
Benjamin Azoulay, chief executive, Oledcomm, to ESA, June 2024What the EIC Project Promised, and What CORDIS Shows
SATELLIFE ran from 1 December 2021 to 30 November 2023; the grant agreement was signed on 8 July 2022, seven months after the official start. The project report says the first protoboard was tested in the lab in June 2022 and in environmental conditions in July 2022, and that two flight models launched on 20 May 2023 on a SpaceX rideshare with OneWeb's satellites, giving "a first flight heritage". It names OneWeb, ArianeGroup, CNES and SpaceX as partners and claims Oledcomm became "the first company in the world" to develop and test LiFi in orbit.

What Has Happened Since
The two "first LiFi in space" claims need a note. The INSPIRE-SAT 7 nanosatellite, built with the LATMOS laboratory and launched in April 2023, carried a SatelLife module; CORDIS instead cites the May 2023 OneWeb launch as the project's flight heritage. Both flights carried Oledcomm hardware.
The Money
Oledcomm files its accounts confidentially. The last figures displayed on Pappers are for 2017, when revenue was €260,000 and the net loss €135,000. The register shows capital increases as recently as October 2025, no insolvency proceedings, and six litigation entries without detail.
What cannot be checked
With no accounts since 2017 and no confirmed close of the 2023 round, the public cannot see how much the space business sells, whether the EIC Fund's equity was invested and on what terms, or how the company is financed today.
Why Europe Should Care
ESA chose to fly Oledcomm's experiment on Ariane 6's first flight, and CNES is working with it on an inter-satellite terminal. The project report says CNES and OneWeb "were impressed by the speed" of development. The strategic case is a European supplier of optical data links with flight heritage, if satellite makers adopt them.
What the project promised
The first LiFi-based wireless system for spacecraft, cutting weight, cost and complexity from satellite harnesses.
What the record shows
A space-qualified module, three flights and high-profile partners, but no announced commercial adoption and no public financial record since 2017.
The Verdict
Proven in space, unproven in the market
SATELLIFE delivered what it promised technically: hardware in orbit within two years of the cut-off, telemetry that CORDIS reports as in line with expectations, and a place on Ariane 6's first launch. What the grant bought is flight heritage, the credential space buyers require. Whether it turns into satellites built without cables, and a business that pays for itself, is not visible in any public record.
