Key takeaways
- Inbound Aerospace raises $1 million for developing autonomous re-entry spacecraft.
- Launch of first re-entry mission is targeted for early 2028.
- Funding will accelerate R&D and validate key sub-systems for spacecraft.
- Spacecraft aims to support microgravity research and commercial applications.
- Focus on cost-effective payload return for emerging industries like pharma and biotech.
Inbound Aerospace, a space-tech startup incubated at IIT Madras, has raised over $1 million in a pre-seed funding round led by Speciale Invest. Notably, the round also saw participation from Piper Serica.
The funding will support the development of autonomous, reusable spacecraft designed for in-orbit experiments, microgravity manufacturing and commercial space research. With a focus on developing a low-Earth orbit-based free-flying and reusable spacecraft for customers, the company aims to launch its first mission by early 2028.
The startup plans to use the capital to accelerate R&D, validate key sub-systems and achieve critical design milestones. Its focus aligns with the growing demand for microgravity research platforms as the International Space Station (ISS) approaches decommissioning in 2030.
“Our spacecraft is designed to enable cost-effective, repeatable and safe return of payloads conducting in-orbit experiments and manufacturing a capability that’s critical to unlocking the next wave of growth in the space economy,” Aravind IB, co-founder and CEO of Inbound Aerospace, said.
Why Re-Entry Vehicles?
Inbound’s vehicles are reportedly positioned to serve emerging use cases in pharma, biotech and materials science. The startup sees potential in supporting India’s BioE3 policy, which promotes space-enabled research.
Speciale Invest, which has now made its sixth space-tech investment, highlighted the strategic role re-entry systems will play in the space economy. “Inbound’s deep-tech ambition spanning autonomy, material science and systems engineering is bold and timely,” Vishesh Rajaram, managing partner at Speciale Invest, said. “They are not just thinking of access to space, but access back from space, which is equally critical.”
Pre-incubated at Nirmaan at the IIT Madras campus and now housed at the institute’s Incubation Cell, Inbound was also the only Indian finalist at Japan’s S-Booster 2025, a space-business competition hosted by the Japanese government.
Previously, in an interview with AIM, Arjun Rao, a founding partner at Speciale Invest, said, “We are in the business of taking risks. As capitalists, we should never forget that. We are not in the business of looking for companies that are not risky.”
He added that in deep tech, “the ability to build disruptive tech and translate that into commercially viable products is key”, a mindset that aligns with Inbound Aerospace’s long-term ambitions.
