Hubble Network Raises $70M in Series B Funding

Why It Matters

It removes the cost and power barriers that have limited satellite IoT, opening global connectivity to billions of low‑cost BLE devices and creating new revenue streams for manufacturers. This could reshape supply‑chain visibility and remote monitoring across multiple industries.

Key Takeaways

• First BLE-to-satellite link using off‑the‑shelf chips.
• 13‑byte payload supports low‑power sensor data.
• Seven‑satellite constellation offers daily global coverage.
• Series B raised $70 million for 60‑satellite expansion.
• Enables cheap IoT for asset tracking, agriculture, consumer safety.

Pulse Analysis

The satellite Internet of Things has long been constrained by expensive radio modules and bulky antennas, limiting its adoption to niche, high‑margin applications. Hubble Network’s debut of a Bluetooth‑to‑satellite link at Embedded World 2026 upends that paradigm by leveraging off‑the‑shelf BLE chips that already power millions of consumer gadgets. By bridging a 650‑kilometre gap with a proprietary ‘Space‑Cloud’ protocol, the company demonstrates that even the smallest sensor can reach orbit without a dedicated cellular modem, dramatically lowering entry costs for global connectivity.

The technical core of Hubble’s offering is a 13‑byte payload optimized for low‑bandwidth telemetry such as temperature, motion or location data. Compatibility with popular microcontrollers from Silicon Labs and Texas Instruments means manufacturers can integrate the service through a lightweight SDK rather than redesigning hardware. High‑gain phased‑array antennas on the LEO satellites amplify the weak BLE signals, while the protocol’s energy efficiency—claimed to be twenty times better than conventional satellite IoT—allows devices to run for years on a single coin cell. This combination of simplicity and power savings is poised to accelerate BLE‑enabled product rollouts.

Backed by a $70 million Series B round that brings total capital to $100 million, Hubble plans to expand its constellation from seven to sixty satellites by 2028, cutting revisit times from 24 hours to roughly 15 minutes. The resulting near‑real‑time coverage opens lucrative markets in asset tracking, pipeline monitoring, precision agriculture and consumer safety, where cost‑sensitive devices have previously been excluded from satellite networks. As enterprises adopt the open developer portal and integrate the SDK, the competitive landscape for low‑cost global IoT is likely to shift, pressuring traditional satellite operators to innovate or partner with BLE‑centric platforms.

Deal Summary

Seattle‑based Hubble Network announced it has closed a $70 million Series B round, bringing total capital to $100 million. The funding will be used to expand its low‑Earth‑orbit satellite constellation to 60 satellites by 2028 and scale its Bluetooth‑to‑satellite IoT connectivity platform.
