Ethereal Exploration Guild, an Indian house tech higher generally known as EtherealX, has climbed 5.5x in valuation to $80.5 million after its newest funding spherical. The startup is growing a launch automobile designed to be totally reusable and is readying engine hot-fire checks forward of its first expertise demonstration flight, deliberate for 2027.
The Bengaluru-based firm confirms that it closed an oversubscribed $20.5 million Collection A spherical led by TDK Ventures and BIG Capital, as TechCrunch reported earlier. Accel, Prosus, YourNest, BlueHill, Campus Fund, and Riceberg Ventures additionally participated, EtherealX stated. The increase follows a $5 million seed spherical in August 2024 that valued the startup at $14.6 million.
As India pushes to mature its house ecosystem past small launchers and part contracts — focusing on development in its house financial system to $45 billion from $8 billion over the subsequent decade — EtherealX is among the many startups drawing consideration.
Satellite tv for pc operators worldwide are searching for extra launch capability and scheduling flexibility in a market the place SpaceX’s Falcon 9 has set the benchmark for pricing and cadence. EtherealX is aiming for that house with its totally reusable automobile designed to return each the booster and higher stage. That’s an method that, if confirmed, may minimize per-launch prices and enhance flight frequency with out counting on a local constellation to maintain rockets totally booked.
EtherealX is growing two engines in-house: the 80-kilonewton “Pegasus” upper-stage engine and the 1.2-meganewton “Stallion” booster engine, with hot-fire checks focused for June–July. Thrust, measured in kilonewtons and meganewtons, signifies how a lot lifting drive an engine can generate.
The startup is focusing on a November–December 2027 launch window for a expertise demonstration automobile, forward of economic missions anticipated to start towards the top of 2028, co-founder and CEO Manu J. Nair stated in an interview.
Rocket engineers additionally monitor particular impulse, a extensively used proxy for gas effectivity, which — together with thrust — helps decide how a lot payload a automobile can carry for a given quantity of propellant.

The Pegasus engine produces 323 seconds of vacuum-specific impulse and makes use of what the startup describes as a proprietary “full-flow segregated cooling cycle.” The engine integrates an in-house additively manufactured turbopump. Moreover, the Stallion booster engine makes use of a gas-generator cycle and delivers 306 seconds of sea-level particular impulse.
Nair instructed TechCrunch that EtherealX plans to cluster a number of engines per stage for its predominant medium-lift automobile, known as Razor Crest Mk-1, with 9 Stallion engines on the booster and 15 Pegasus engines on the higher stage.
For comparability, SpaceX’s Falcon 9 primarily reuses its first-stage booster whereas expending the higher stage. EtherealX is focusing on deeper reusability by designing its automobile to return each the booster and the higher stage.
EtherealX’s automobile goals to hold as much as 24.8 tons in an expendable configuration, 22.8 tons partially reusable, and about 8 tons when totally reusable. The startup is focusing on pricing of $350 to $2,000 per kilogram over time, Nair stated, relying on configuration and cadence.
To help growth, EtherealX operates a rocket engine check website within the southern Indian state of Tamil Nadu, generally known as Base 001, which Nair stated is targeted on upper-stage engine qualification. The startup has additionally secured a 150-acre manufacturing and testing campus in Andhra Pradesh’s proposed house metropolis that it expects to change into operational from mid-2026 for built-in engine and stage testing.
EtherealX has signed launch memoranda of understanding totaling round $130 million with prospects, together with Japan’s House BD and Taiwan’s house company, TASA, Nair stated, because it seeks early business demand forward of its first demonstration flight.
The newest funding will probably be used to finish flight qualification of the Stallion booster engine and to run clustered-firing checks of the Pegasus upper-stage engines, Nair stated. To help that ramp-up, the startup presently employs 67 folks and expects to develop to about 90 over the subsequent two months because it will increase manufacturing capability and strikes to the next testing cadence forward of its first demonstration flight.
