Seraphim Space Investment Trust (SSIT) is investing a further $30 million into Hubble Network. Hubble is building a satellite-powered Bluetooth network, enabling standard off-the-shelf Bluetooth low energy chips to connect directly to space without cell towers, gateways or custom hardware. Seraphim Space announced its latest investment, Aug. 18.
Hubble is an existing portfolio company of Seraphim Space Venture Fund II (SSVII). The investment represents the first addition of a new portfolio company to SSIT using the proceeds of the company’s successful 137 million pound ($185.7 million) C Share issue.
Hubble has raised more than $100 million to date, including a $70 million Series B funding round led by Swagar Capital in September 2025. Its investor base includes Y Combinator, Ryan Swagar, Tom Gonser, and Mike Farley. Hubble’s strategic partnerships include Life360, Tile, Texas Instruments, InPlay, and Samsara, which give the company access to a terrestrial tracking network of more than 90 million smartphones and support integration into connected devices and IoT applications.
“One of the key advantages of Seraphim’s multi-stage investment strategy is our ability to identify promising companies early, support their development through our early-stage venture funds and, where appropriate, enable SSIT to invest in the subsequent growth rounds of the most exceptional performers. Hubble is a compelling example of that strategy in action, having rapidly progressed from an early-stage investment to a growth-stage business with seven satellites in orbit, a terrestrial network of more than 100 million,” James Bruegger, chief investment officer of Seraphim Space Manager, said in a statement.
