Hubble Network Secures $200M to Expand Bluetooth Satellite Constellation
Hubble Network, a Seattle-based startup, raised $200 million in Series C funding led by Smith Point Capital, bringing its total financing to $300 million. The company plans to deploy 54 additional satellites by 2029, each with ten times more Bluetooth-detecting antennas, to enable tracking of billions of devices. Its space-based asset tracking service has moved from closed beta to general availability.
The Series C brings Hubble's cumulative funding to $300 million, with prior backing including a $70M Series B from September 2025. Investors in the latest round span Smith Point Capital, Seraphim, Carthona Capital, Earthshot Ventures, RPM Ventures, and Y Combinator.
Hubble's approach relies on a firmware modification letting standard Bluetooth chips transmit small data packets over vast distances. This keeps hardware costs under 50 cents per chip versus roughly $50 for cellular alternatives, with battery life extending to years. The company also operates over 100 million ground-based Bluetooth gateways to complement satellite coverage in urban areas, and next-generation satellites will capture environmental readings like temperature, humidity, and CO2 alongside location data.
This funding could reshape how industries track physical assets. Logistics firms, agricultural operations, and supply chain managers may gain near-constant visibility into equipment location and condition at a fraction of current costs, potentially lowering insurance premiums and reducing losses from theft or spoilage. Consumers may indirectly benefit through cheaper goods and fresher produce. However, widespread tracking of billions of devices raises privacy questions — the same infrastructure that monitors cargo could theoretically monitor people's personal electronics. Regulators and companies will need to balance efficiency gains against surveillance concerns as this technology scales.
