Hubble Network Raises $200 Million to Open Its Satellite Bluetooth Network to Everyone

Seattle-based Hubble Network closed a $200 million Series C round led by Smith Point Capital, with participation from Seraphim, Carthona Capital, Earthshot Ventures, Y Combinator and RPM Ventures, valuing the company at $1.6 billion. The round brings Hubble's total funding to $300 million, meaning this single Series C round is worth two-thirds of everything the company has raised since founding.

The company's core idea is straightforward to state and genuinely difficult to build: extending Bluetooth connectivity, the short-range wireless standard already built into billions of existing devices, to work from low Earth orbit satellites, so any Bluetooth-enabled device can be located or communicate with no new hardware required on the device side. Hubble currently operates six satellites in low Earth orbit and plans to expand that constellation to 60 satellites by 2030, a tenfold increase in coverage capacity over the next several years.

Why Opening the Network to All Bluetooth Devices Is the Real News

The round announcement coincided with Hubble opening its satellite coverage to all Bluetooth devices generally, rather than keeping the technology limited to a smaller set of partner hardware, a shift from a curated pilot model to genuine general availability. That distinction matters more than the funding figure on its own: a company can raise a large round on the strength of a promising pilot, but opening general availability is the point where a satellite connectivity business actually starts proving out usage at scale rather than in controlled partner deployments. Hubble's existing Terrestrial Network already spans more than 100 million gateways across 170 countries and 3 million square miles of coverage, with more than 500,000 devices currently active on the network, over ten times the number active a year earlier, giving the company a genuinely large existing user base to expand satellite coverage into rather than starting the general-availability push from zero.

What This Means for Founders

Hubble's raise is a useful marker for any founder building infrastructure meant to work invisibly underneath an existing, massive installed base rather than requiring users to adopt new hardware. The company's entire value proposition depends on working with Bluetooth devices that already exist in the world by the billions, not asking device makers or consumers to adopt anything new, and that decision to build for an existing standard rather than a proprietary one appears to have been central to both the tenfold device growth and the willingness of investors to back a $1.6 billion valuation at this stage. A founder building deep infrastructure or connectivity technology should treat the choice between extending an existing widely-adopted standard versus introducing a new proprietary one as one of the highest-leverage decisions in the company's early architecture, well before a fundraising narrative gets built around whichever choice was made.
