NextFin News - Ethereal Exploration Guild, known as EtherealX, a Bengaluru-based Indian space technology startup, announced a significant milestone on January 15, 2026. The company successfully closed an oversubscribed Series A funding round, raising $20.5 million led by TDK Ventures and BIG Capital, with participation from Accel, Prosus, YourNest, BlueHill, Campus Fund, and Riceberg Ventures. This funding round catapulted EtherealX’s valuation to $80.5 million, a 5.5-fold increase from its $14.6 million valuation during its seed round in August 2024.
EtherealX is developing the Razor Crest Mk-1, a fully reusable medium-lift launch vehicle designed to rival SpaceX’s Falcon 9. The startup is pioneering two proprietary liquid rocket engines: the Stallion booster engine with 1.2 MN thrust and the Pegasus upper stage engine delivering 80 kN thrust. Both engines are slated for critical hot-fire tests in June-July 2026 at EtherealX’s Base 001 test facility in Tamil Nadu and a forthcoming 150-acre integrated testing campus in Andhra Pradesh’s proposed space city. The company aims to demonstrate full-stage reusability by recovering both booster and upper stages, a step beyond SpaceX’s booster-only recovery approach.
Technically, the Razor Crest Mk-1 offers flexible payload configurations: 24.8 tonnes to low Earth orbit (LEO) in expendable mode, 22.8 tonnes partially reusable, and 8 tonnes fully reusable. Pricing is projected between $350 and $2,000 per kilogram depending on reusability and flight cadence. EtherealX has secured memoranda of understanding worth approximately $130 million from international clients including Japan’s SpaceBD and Taiwan’s TASA, signaling strong commercial interest ahead of its first demonstration flight targeted for late 2027 and commercial operations in 2028.
The startup currently employs 67 staff, with plans to expand to 90 by mid-2026 to support accelerated engine testing and production. The Series A funding will primarily finance the completion of Stallion engine qualification and Pegasus engine cluster firing tests, critical milestones before the demonstration flight.
India’s space economy, valued at $8 billion, is projected to grow to $45 billion over the next decade, driven by government initiatives and private sector innovation. EtherealX competes domestically with startups like Agnikul Cosmos and Skyroot Aerospace, but its focus on full reusability and clustered engine architecture positions it uniquely in the Asian market outside China, Japan, and South Korea.
The valuation surge reflects investor confidence in EtherealX’s technology roadmap and market potential. The company’s approach leverages in-house additive manufacturing for turbopumps and clustered engine designs, aiming to reduce launch costs and increase flight frequency. This strategy aligns with global trends emphasizing reusability to disrupt traditional expendable launch economics.
Looking ahead, EtherealX’s success hinges on the outcomes of the upcoming engine hot-fire tests and the ability to scale manufacturing and supply chain operations efficiently. If successful, EtherealX could catalyze a new era of competitive launch services from India, challenging SpaceX’s dominance and expanding global launch capacity amid increasing satellite deployment demands.
Moreover, EtherealX’s progress underlines the strategic importance of India’s space sector under U.S. President Trump’s administration, which has shown interest in fostering international space partnerships and competition. The startup’s advancements may attract further cross-border investments and collaborations, enhancing India’s role in the global space economy.
In conclusion, EtherealX’s 5.5x valuation jump ahead of critical engine tests is a clear indicator of India’s rising ambitions in reusable rocket technology. This development not only intensifies competition in the medium-lift launch segment but also signals a broader shift towards sustainable, cost-effective space access solutions. Investors and industry stakeholders will closely monitor EtherealX’s engine test results and demonstration flight, which will be pivotal in validating its technological claims and commercial viability in the coming years.
