I am surprised that Starlink didn't eat their lunch. I think the only thing keeping them alive is inertia and the fact that Starlink still has regional lockouts and doesn't work in the most remote parts of the world.
replyGarden variety Starlink requires a big, expensive, high-powered phased-array antenna, and there are lots of low-power/IoT-type applications served by Iridium for which Starlink is not suitable. Once the Starlink direct-to-cell technology matures, presumably that'll serve those usecases, but it still seems pretty nascent.
replyIridium still has a monopoly on high latitudes, too, AFAIK. Their USP is being the only network that works literally anywhere on the surface of the earth.
replyStarlink works at high attitudes. It was a big deal when they got it at McMurdo 4 years ago. Same in Utqiagvik (formerly Barrow) Alaska.
replyUnder SOLAS, GMDSS equipment is mandatory on ships. Iridium (and Inmarsat) meet that requirement, starlink does not - hence Iridium is still very much around...
replyThere are countless niches like this in telematics, one of the only industries I've encountered where a seemingly established company will be doing a "Series K" round, typically as a means to buy or build out the infrastructure they need for whatever customer.
