India’s private space race just picked up serious momentum. EtherealX, formally known as Ethereal Exploration Guild, has seen its valuation soar 5.5 times to $80.5 million following a fresh round of funding — a major leap that puts the Bengaluru-based startup firmly on the global launch-services radar.

The funding comes as EtherealX accelerates work on a fully reusable launch vehicle, with engine hot-fire tests lined up this year and its first technology demonstration flight targeted for 2027.

Oversubscribed Series A Signals Strong Investor Confidence

EtherealX confirmed it has closed an oversubscribed $20.5 million Series A round, led by TDK Ventures and BIG Capital. The round also saw participation from Accel, Prosus, YourNest, BlueHill, Campus Fund, and Riceberg Ventures.

This marks a sharp jump from EtherealX’s $5 million seed round in August 2024, when the startup was valued at just $14.6 million. The rapid valuation climb reflects growing confidence in India’s emerging private launch ecosystem — and in EtherealX’s ambitious engineering roadmap.

Targeting a Bigger Slice of India’s Expanding Space Economy

India is pushing hard to expand its space economy from $8 billion today to $45 billion over the next decade, moving beyond small launchers and component contracts. EtherealX is positioning itself squarely within that next phase, where medium-lift, reusable rockets could reshape access to orbit.

Globally, satellite operators are demanding more launch slots, better scheduling flexibility, and lower costs — a market currently dominated by SpaceX and its Falcon 9 rocket. EtherealX believes its fully reusable approach — recovering both the booster and the upper stage — could eventually offer a competitive alternative.

Two In-House Engines, Big Reusability Ambitions

At the heart of EtherealX’s program are two engines being developed entirely in-house:

• Pegasus: an 80-kilonewton upper-stage engine delivering 323 seconds of vacuum-specific impulse, featuring a proprietary full-flow segregated cooling cycle and an additively manufactured turbopump.
• Stallion: a 1.2-meganewton booster engine using a gas-generator cycle, producing 306 seconds of sea-level specific impulse.

Hot-fire tests for both engines are scheduled for June–July, a key milestone ahead of flight qualification.

The company plans to cluster nine Stallion engines on the booster and 15 Pegasus engines on the upper stage for its main vehicle, Razor Crest Mk-1 — a configuration aimed at balancing power, efficiency, and reusability.

Launch Timeline and Payload Targets

EtherealX is targeting a November–December 2027 window for its first technology demonstration flight, with commercial launches expected toward the end of 2028, according to co-founder and CEO Manu J. Nair.

Payload capabilities for Razor Crest Mk-1 are ambitious:

• 24.8 tonnes in expendable mode
• 22.8 tonnes with partial reusability
• Around 8 tonnes when fully reusable

Over time, the startup aims to bring launch prices down to $350–$2,000 per kilogram, depending on mission configuration and cadence.

Infrastructure, Test Sites, and Early Customer Interest

To support development, EtherealX operates Base 001, a rocket engine test facility in Tamil Nadu, currently focused on upper-stage engine qualification. The company has also secured a 150-acre manufacturing and testing campus in Andhra Pradesh’s proposed space city, expected to go live by mid-2026.

On the commercial side, EtherealX says it has already signed launch MoUs worth around $130 million, including agreements with Japan’s SpaceBD and Taiwan’s TASA — a strong early signal of demand ahead of its first demo flight.

What the New Funding Will Power Next

The fresh capital will be used to:

• Complete flight qualification of the Stallion booster engine
• Conduct clustered-firing tests of the Pegasus upper-stage engines
• Scale manufacturing and testing cadence

EtherealX currently employs 67 people and expects to grow to around 90 employees in the coming months as it ramps up toward flight readiness.

Final Words

EtherealX’s rapid valuation jump underscores how quickly India’s private space ambitions are gaining traction. With a fully reusable rocket, in-house engine development, and early commercial commitments already in place, the startup is shaping up to be one of the most closely watched players in India’s next-generation launch market. The real test now lies ahead — when metal meets flame and theory turns into flight.
