Bellatrix Aerospace
Indian startup building electric and green propulsion thrusters and orbital transfer vehicles for satellites.
On the record
Checkpoint: Pushpak OTV first ISRO-integrated launch, originally expected early 2026
The call
Bellatrix has real hardware flying and ISRO ties, but survival still depends on converting backlog into revenue and landing the Pushpak launch on schedule.
Bellatrix Aerospace builds thrusters and orbital tugboats for satellites and spacecraft. It has actually flown hardware on Indian space missions and signed a contract with India's national space agency, which is hard to fake and gives it real credibility, but competitors like Manastu Space in India and larger global companies can copy or outbuild its technology. The company raised only $31 million over a decade and faces a tight deadline: it said in early 2026 that its $20 million in new funding must pay for work it already promised to deliver, so if it fails to convert that backlog into completed projects over the next few quarters, investors may lose confidence and funding could dry up.
Why
01
AI pressure: None apparent. No AI product threatens this hardware business directly; autonomy software could later feed into their OTV guidance systems. Could AI do the core job? Unlikely.
02
Bigger players: Manastu Space and global in-space mobility players like Momentus. Manastu also flies propulsion hardware on ISRO platforms, competing for the same domestic contracts and customer trust. Could a giant copy it? Probably.
03
What protects it. Real flight heritage on ISRO's POEM missions and a signed NSIL contract give it institutional trust that's hard for new entrants to copy fast.
What would change this call
Pushpak OTV first ISRO-integrated launch occurs or slips past early 2026 into 2027. Shows whether flagship NSIL contract is converting to real flight, or stalling.
Next funding round terms and timing after the March 2026 $20M raise. Flat, down, or delayed round would signal weakening investor confidence.
Backlog conversion to signed recurring revenue over next 2-3 quarters. Tests whether claimed multi-million backlog turns into real paying contracts.

Key numbers
- ~$31M raised total over 10 years
- Post-money valuation $100-105M
- $20M pre-Series B closed
Named risks
- Pushpak OTV first ISRO-integrated launch expected early 2026 remains unconfirmed as of July 2026.
- Multi-million-dollar backlog conversion into delivered revenue over next 2-3 quarters is unproven.
- Indian launch ecosystem reliability risk after PSLV-C62 failed to reach orbit on January 12, 2026.
- Well-funded domestic peers Digantara and Manastu Space pressure capital access and customer acquisition.
- Project 200 ultra-LEO large-scale demonstration targeted for 2026 carries binary technical outcome risk.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| Manastu Space | contesting | Flight-tested Vyom 2U green thruster on ISRO POEM-4 in December 2024, matching Bellatrix's flight lane |
| Digantara | gaining on | Raised $50 million Series B for global expansion, announced July 13, 2026 |
| Orbion Space Technology | gaining on | Became wholly owned subsidiary of York Space Systems in 2026, per NASA survey dated 2026-05-18 |
| Dawn Aerospace | contesting | Company states it raised a $25 million Series B for its green bipropellant CubeDrive systems (vendor-claimed) |
Questions people ask
- Is Bellatrix Aerospace profitable?
- No confirmed profitability data exists. Bellatrix Aerospace has raised roughly $31 million total funding as of March 2026, including a $20 million Pre-Series B closed March 27-30, 2026, and remains dependent on converting its stated multi-million-dollar order backlog into recurring revenue.
- Who owns Bellatrix Aerospace?
- Bellatrix Aerospace is privately held and venture-backed, founded in 2015 by Rohan Ganapathy and Yashas Karanam. Its March 2026 Pre-Series B was led by Cactus Partners with Hero Investment Office, 35North Ventures, GrowX Ventures and others, valuing the company at $100-105 million post-money.
- Could AI replace Bellatrix Aerospace's engineers?
- Unlikely in the near term. Bellatrix's core work is physical propulsion hardware and propellant chemistry requiring flight qualification cycles reported at 5,000+ hours as of March 2026, tasks that depend on physical testing rather than software automation.
- Who is Bellatrix Aerospace's biggest competitor in India?
- Manastu Space is the closest domestic rival, an IIT Bombay-founded green propulsion maker that flight-tested its Vyom 2U thruster on ISRO's POEM-4 platform in December 2024, matching Bellatrix's own POEM flight heritage in the same propulsion niche.
- What is the Pushpak Orbital Transfer Vehicle and has it launched?
- Pushpak is Bellatrix's in-space tug for satellite last-mile deployment, contracted with NSIL in October 2024 with a first ISRO-integrated launch expected early 2026. As of July 2026 that launch status was not publicly confirmed.
- How much funding has Bellatrix Aerospace raised?
- Bellatrix has raised roughly $31 million total as of March 2026, including an $8 million Series A closed June 2022 and a $20 million Pre-Series B closed March 27-30, 2026, at a post-money valuation of $100-105 million.
