Key Takeaways
- • Hubble Network closed a $200 million Series C led by Smith Point Capital on September 23, 2026, valuing the Seattle-based satellite-IoT company at $1.6 billion with approximately $300 million in cumulative funding.
- • The funding round includes participation from Seraphim, Carthona Capital, Earthshot Ventures, Y Combinator, and RPM Ventures, with proceeds directed toward expanding Hubble's 60-satellite low-Earth-orbit constellation for Bluetooth LE device connectivity.
- • Hubble's Series C positions the company at a critical infrastructure inflection point, where capital deployment now directly funds orbital constellation build-out and market validation of satellite-based IoT connectivity as an alternative to terrestrial networks.
- • The $1.6 billion valuation reflects institutional confidence in space-IoT infrastructure as a venture asset class, with strategic investors spanning deep-tech focused funds (Seraphim), regional growth capital (Carthona, RPM), and flagship accelerators (Y Combinator).
Summary
Hubble Network, a Seattle-based developer of Bluetooth-to-satellite connectivity infrastructure, announced on September 23, 2026 that it has raised $200 million in Series C funding led by Smith Point Capital, bringing the company's valuation to $1.6 billion and its cumulative capital raised to approximately $300 million. The round was confirmed by the company's announcement and corroborating coverage from GeekWire and SiliconANGLE.
The Series C syndicate includes established space-focused venture investors Seraphim, growth-stage capital partners Carthona Capital and Earthshot Ventures, Y Combinator, and RPM Ventures. This investor composition reflects both specialized conviction around satellite infrastructure and broad institutional appetite for space-IoT applications. The capital will be deployed toward expanding Hubble's low-Earth-orbit satellite constellation, which is designed to ultimately comprise 60 satellites capable of providing Bluetooth LE connectivity to distributed IoT devices globally.
Hubble's funding trajectory and valuation milestone indicate accelerating traction in the satellite-IoT segment. The company's technical focus—bridging Bluetooth LE devices directly to orbital infrastructure—addresses a distinct connectivity use case for assets operating beyond terrestrial coverage, including maritime, aviation, remote industrial, and emergency-response applications. With $300 million now deployed across its capital history, Hubble is transitioning from prototype validation to production-scale constellation deployment, a phase typically requiring substantial capital and supply-chain execution.
For allocators tracking the intersection of venture capital, space infrastructure, and IoT expansion, Hubble's Series C represents a material validation event: a $1.6 billion valuation from a diversified investor base including both deep-tech specialists and generalist growth funds signals that satellite-IoT connectivity has graduated from research to fundable infrastructure. The company's multi-satellite build pathway and satellite-specific investor presence indicate that near-term milestones will likely include orbital testing, regulatory approvals, and commercial customer deployments.
