How EtherealX and Manu Nair Are Challenging SpaceX from India

In this episode, Manu Nair, Co-Founder and CEO of EtherealX, breaks down the engineering breakthroughs, fundraising battles, and geopolitical forces reshaping the future of space tech in India and beyond.  

Over 85% of the world's commercial satellite launches depend on a single rocket from a single country. That's not a monopoly - it's a dependency, and Manu Nair believes it is one of the most dangerous structural flaws in global space infrastructure today. Manu is the Co-Founder and CEO of EtherealX, the Bengaluru-based deep tech startup building the Razor Crest Mk-1 - India's first fully reusable medium-lift launch vehicle that recovers both its booster and upper stage.  

In a conversation with host Akshay Datt, Manu traces the journey from bootstrapping on personal savings and a loan from his father, to closing a $20.5 million Series A co-led by TDK Ventures and Accel, to signing binding launch agreements with Japanese, Taiwanese, and European space agencies. He reveals the proprietary rocket engine cycle EtherealX developed, the first new feed cycle in six decades of rocketry, which harnesses re-entry plasma heat as a thermodynamic resource rather than fighting it with heavy ceramic shields.  

He also shares why the economics of partial reusability are a dead end, why super-heavy rockets make no commercial sense for everyday satellite deployment, and why EtherealX's long-term roadmap extends from orbital launch vehicles all the way to small modular nuclear reactors.   

A candid, technically rich, and deeply inspiring episode at the intersection of space tech, deep tech investing, India's policy renaissance, and civilisational ambition.  

Key Highlights 

👉Why 85% of global payloads riding one rocket is a civilisational risk, and how EtherealX is building the alternative the world needs 

👉The FFSCC breakthrough - how EtherealX invented a new rocket engine cycle that turns re-entry heat into fuel, enabling full upper-stage recovery for the first time in the medium-lift class

 👉How Manu and his co-founders bootstrapped for a year, raised a $360K milestone round, and eventually closed $26.3 million across four rounds to build India's highest pressure-rated private rocket engine test facility 

👉Why the economics of large rockets like Starship don't work for routine commercial LEO deployment, and why the medium-lift segment will remain the engine of the global space economy for the next decade 

👉India's regulatory renaissance - the FDI reforms, the Rs 1,000 crore IN-SPACe VC fund, and how ISRO's shift from gatekeeper to enabler created the conditions for EtherealX to exist 

👉Why EtherealX's long-term roadmap includes fusion-based small modular reactors to power AI data centres on Earth, and why putting data centres in orbit is a dangerous mistake
