On Sept. 23, 2026, direct-to-satellite IoT operator Hubble Network announced the completion of a $200 million Series C financing round, raising the company’s private market valuation to $1.6 billion.
Led by Smith Point Capital, the funding round included participation from Seraphim, Carthona Capital, Earthshot Ventures, RPM Ventures, and Y Combinator.
The investment brings Hubble Network’s total venture capital raised to $300 million, building on a $70 million Series B round closed in September 2025.
Network Growth and Orbital Demonstration Hardware
The capital injection follows operational growth across Hubble Network’s terrestrial and space segments. The company currently manages over 500,000 active devices across its ground network, representing a tenfold expansion over the past twelve months.
The space segment relies on six demonstration cubesats built by Spire Global, which receive standard Bluetooth Low Energy (BLE) transmissions directly from unmodified terrestrial hardware in low Earth orbit. Operating over North America, these initial six spacecraft complete daily data reception passes, validating space-based Bluetooth signal acquisition without requiring external satellite dish equipment or modified chipsets.
Hardware Specifications and Next-Generation Constellation Scale
The Series C proceeds will fund the design, fabrication, and deployment of up to 60 larger, custom-engineered satellites targeted for full orbital deployment by 2030.
The upgraded spacecraft bus incorporates specialized phased-array antenna systems designed to overcome spatial attenuation and atmospheric noise. The next-generation platforms will feature ten times the antenna surface area of the initial Spire-built demonstration cubesats, increasing signal sensitivity and link margins for low-power Bluetooth chips on the ground.
Each upgraded satellite will be capable of simultaneously tracking and processing data transmissions from more than 10 million individual connected devices, expanding capacity for global asset tracking, supply chain monitoring, and industrial IoT applications.
Launch Schedule and Deployment Roadmap
Hubble Network will proceed with payload assembly and flight software qualification for its next-generation satellite platform. The first two upgraded spacecraft are scheduled to launch in 2027, establishing the baseline operational architecture for the planned 60-satellite global Bluetooth constellation.
