Hubble Network Raises $70M Series B to Expand Satellite Bluetooth Network
Hubble Network secured $70 million in Series B funding to support the deployment of a 60-satellite constellation, aiming to connect up to one billion Bluetooth devices globally by 2028. The Seattle-based company announced the funding on September 17th 2025, raising its total capital to $100 million since the company was founded in 2021.
According to co-founder and CEO Alex Haro, “Our vision has always been to connect billions of devices seamlessly and cost-effectively, without requiring hardware or infrastructure. This round confirms the strong demand for scalable, low-power, global IoT connectivity.” Haro continued, “The plan is to fund the constellation through a mix of equity investments from investors and customer revenue as we scale. What this raise really gives us is the runway to prove commercial traction at scale, which makes financing the rest of the constellation much easier.”
Hubble reports having more than ten pilot customers, each with millions of devices that could leverage its enterprise-focused Bluetooth tracking network. The service is designed to function similarly to Apple’s Find My and Google’s Find My Device, but without dependency on terrestrial infrastructure.
In August, Hubble ordered two 500-kilogram MuSat XL satellite buses from California-based manufacturer, Muon Space, for planned deployment in 2027. These satellites will supplement seven smaller cubesats previously launched into low Earth orbit by Spire Global, which facilitated the first direct Bluetooth connection to a satellite last year.
Haro explained that Hubble designs and builds its payloads and antenna arrays internally, while partnering with firms such as Muon and Spire for the satellite buses. “Our constellation will feature a combination of buses from Muon, Spire, and other manufacturers. This flexibility allows for rapid development while maintaining our focus on Bluetooth-to-satellite technology,” Haro noted.
The Series B round was led by Swagar Capital. Additional investors include: Tom Gonser, founder of DocuSign; Mike Farley, cofounder of Tile; Marc Weiser, managing director of RPM Ventures; as well as venture accelerator Y Combinator and Seraph Group founder, Tuff Yen. “Hubble is doing what many thought was impossible, making space accessible for everyday devices,” Swagar said. “Their unique architecture, strong technical execution and proven customer demand position them to define the future of global connectivity.”
