Hubble Network’s $30M B-II: Seraphim Doubles Down on Space Bluetooth
Seraphim Space Investment Trust invested $30M into Hubble Network (Series B-II) — satellite-powered Bluetooth that talks to off-the-shelf BLE chips. Prior $70M Series B (2025). Y Combinator is a historical backer with a /fund/ page here; Seraphim is not.

Hubble Network took a $30 million investment from Seraphim Space Investment Trust (SSIT) announced August 18, 2026 — labeled Series B-II by secondary databases. Y Combinator is a historical backer; Seraphim has no /fund/ page here.
Unexpected truth: this is not a fresh seed story. It is a listed SpaceTech trust recycling C Share proceeds into a company it already knew through Venture Fund II — with seven satellites on orbit and a smartphone-scale terrestrial network claim.
This page is for space/IoT scouts. Last verified August 31, 2026. Primary: SSIT RNS / Via Satellite.
Five-minute decision
| If you need… | Verdict |
|---|---|
| What happened | Funded. $30M from SSIT. B-II label. |
| What Hubble is | Satellite-powered Bluetooth for off-the-shelf BLE chips. |
| Whether it is shipping | Hardware on orbit (7 sats) + partner network claims. |
| Whether to diligence | Yes, if BLE asset tracking without gateways is your wedge. |
Investigate further when: you need global IoT connectivity without custom radios.
Wait or pass when: you need a US venture /fund/ lead on this tranche.
What happened
| Field | Detail |
|---|---|
| Company | Hubble Network, Inc. |
| This check | $30M from SSIT · Aug 18, 2026 |
| Prior | $70M Series B · Sep 2025 · Swagar Capital lead |
| Total | >$100M (Seraphim) |
| Orbit | 7 satellites (Seraphim statement) |
| Historical | YC, Ryan Swagar, Tom Gonser, Mike Farley |
SSIT: first new portfolio company funded from the £137M C Share issue; C Share deployment crossed the £40M partial-conversion threshold.
Who uses it — and why Seraphim fits
Users / partners named: Life360, Tile, Texas Instruments, InPlay, Samsara. Job: low-cost global connectivity and asset tracking for BLE-enabled devices — connect standard chips directly to space without cell towers, gateways, or custom hardware. Terrestrial assist network cited at 90M+ smartphones (Via Satellite) / >100M (Seraphim CIO quote).
Why Seraphim writes this check: textbook multi-stage SpaceTech thesis — early support via SSVII, then SSIT growth capital once satellites and partnerships de-risk the story. James Bruegger’s statement is explicit: identify early, support through venture funds, then follow with the listed trust. Likely reason Hubble takes SSIT money: patient space capital that already understands constellation and regulatory timelines, not a generalist SaaS fund discovering BLE in week one.
Why now
C Share dry powder needed deployment; Hubble had graduated from early-stage to growth with hardware in orbit. Direct-to-device connectivity is the crowded narrative — Hubble’s differentiation claim is BLE commodity silicon, not a proprietary phone modem.
What is not proven
- RNS details SSIT’s $30M; co-investor participation in this tranche unclear.
- Network size claims are company/partner marketing.
- Unit economics of satellite BLE messaging not disclosed.
Competitive map
| Approach | Hubble contrast |
|---|---|
| Cellular IoT / LoRa gateways | Needs terrestrial infrastructure |
| Proprietary D2D constellations | Often custom silicon |
| Hubble | Pitch: use chips already in consumer/IoT devices |
Implication
The unresolved issue is whether BLE-to-space becomes a default IoT radio path or stays a niche tracking overlay. Watch partner device volume (Tile/Life360/Samsara class) more than satellite count alone.
