## Content

Starcloud raises $170M at $1.1B valuation. Company slogan: "demand for compute outpaces Earth's limits." Plans to scale from proof-of-concept to constellation using three distinct launch vehicle tiers.

**Three-tier roadmap (from funding announcement and company materials):**

| Satellite | Launch Vehicle | Launch Date | Capability |
|-----------|---------------|-------------|------------|
| Starcloud-1 | Falcon 9 rideshare | November 2025 | 60 kg SmallSat, NVIDIA H100, trained NanoGPT on Shakespeare, ran Gemma (Google open LLM). First AI workload demonstrated in orbit. |
| Starcloud-2 | Falcon 9 dedicated | Late 2026 | 100x power generation over Starcloud-1. NVIDIA Blackwell B200 + AWS blades. "Largest commercial deployable radiator ever sent to space." |
| Starcloud-3 | Starship | TBD | Constellation scale. 88,000-satellite target. GW-scale AI compute for hyperscalers (OpenAI named). |

**Proprietary thermal system:** Leverages "free radiative cooling" in space. Stated cost advantage: $0.002-0.005/kWh (vs terrestrial cooling costs). Starcloud-2's "largest commercial deployable radiator" is the first commercial test of scaled radiative cooling in orbit.

**Cost framing:** Starcloud's white paper argues space offers "unlimited solar (>95% capacity factor) and free radiative cooling, slashing costs to $0.002-0.005/kWh."

**Hyperscaler targets:** OpenAI mentioned by name as target customer for GW-scale constellation.

## Agent Notes

**Why this matters:** Starcloud's own roadmap is the strongest single piece of evidence for the tier-specific launch cost activation model. The company built its architecture around three distinct vehicle classes (Falcon 9 rideshare → Falcon 9 dedicated → Starship), each corresponding to a different compute scale. This is a company designed from first principles around the same tier-specific structure I derived analytically.

**What surprised me:** The 88,000-satellite constellation target with OpenAI as target customer. The scale ambition (88,000 satellites for GW compute) requires Starship at full reuse. Starcloud is essentially banking on Starship economics clearing to make the GW tier viable — a direct instantiation of the tier-specific keystone variable model.

**What I expected but didn't find:** A timeline for Starcloud-3 on Starship. No date given. The Starship dependency is acknowledged but not scheduled — consistent with other actors (Blue Origin Project Sunrise) treating Starship-scale economics as necessary but not yet dateable.

**KB connections:**
- Primary: [[launch cost reduction is the keystone variable that unlocks every downstream space industry at specific price thresholds]] — Starcloud-3 requiring Starship is direct evidence
- Primary: [[Starship achieving routine operations at sub-100 dollars per kg is the single largest enabling condition for the entire space industrial economy]] — Starcloud-3 constellation explicitly depends on this
- Secondary: [[the space manufacturing killer app sequence is pharmaceuticals now ZBLAN fiber in 3-5 years and bioprinted organs in 15-25 years each catalyzing the next tier of orbital infrastructure]] — ODC may be faster-activating than pharmaceutical manufacturing

**Extraction hints:**
- Extract: "Starcloud's three-tier launch vehicle roadmap (Falcon 9 rideshare → Falcon 9 dedicated → Starship) directly instantiates the tier-specific launch cost threshold model, with each tier unlocking an order-of-magnitude increase in compute scale."
- Extract: "ODC proof-of-concept is already generating revenue (Starcloud-1 demonstrates AI workloads in orbit); GW-scale constellation deployment explicitly requires Starship-class economics — confirming the tier-specific keystone variable formulation."
- Note: The thermal cost claim ($0.002-0.005/kWh) may be extractable as evidence that radiative cooling is a cost ADVANTAGE in space, not merely a constraint.

**Context:** Starcloud is YC-backed, founded in San Francisco. Starcloud-1 was the world's first orbital AI workload demonstration (November 2025). The $170M Series A is the largest funding round in the orbital compute sector to date as of March 2026. Company positioning: "data centers in space" as infrastructure layer.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: [[launch cost reduction is the keystone variable that unlocks every downstream space industry at specific price thresholds]]
WHY ARCHIVED: Strongest direct evidence for the tier-specific activation model — a single company's roadmap maps perfectly onto three distinct launch cost tiers (rideshare → dedicated → Starship). Also the first major ODC funding round, marking commercial activation of the sector.
EXTRACTION HINT: Extract the tier-specific roadmap as a claim. The claim title: "Starcloud's three-tier roadmap (rideshare → dedicated → Starship) directly instantiates the tier-specific launch cost threshold model for orbital data center activation." Confidence: likely. Cross-reference with Aetherflux and Axiom+Kepler for sector-wide evidence.
