Why Is IIT Madras-incubated Inbound Aerospace Making Headlines?
On July 23, 2025, IIT Madras-incubated Inbound Aerospace raised over $1 million in a pre-seed funding round led by Speciale Invest, with participation from Piper Serica. This milestone marks a significant step for India’s private space-tech ecosystem, particularly in the niche of autonomous re-entry spacecraft. Founded in 2025 by Aravind I B, Vishal Reddy, and Capt (IN) Abhijit Bhutey (Retd), the startup is developing reusable vehicles to deliver and return experiments between Earth and space, addressing the growing need for microgravity infrastructure post-ISS retirement in 2030.
Why this matters: The global space economy is projected to reach $1.8 trillion by 2035, with microgravity research driving advancements in biotech, pharma, and materials science. Inbound Aerospace’s focus on cost-effective, reusable spacecraft positions it as a pioneer in this high-growth sector.
What Are Autonomous Re-entry Spacecraft and Why Do They Matter?
Autonomous re-entry spacecraft are vehicles designed to travel to low Earth orbit (LEO), conduct experiments in microgravity, and return payloads safely to Earth without human intervention. Unlike traditional spacecraft, these vehicles are reusable, reducing costs and enabling frequent missions. Inbound Aerospace’s spacecraft are tailored for in-orbit testing, microgravity manufacturing, and commercial space research.
How Do Re-entry Vehicles Work?
These spacecraft are deployed in LEO, typically at altitudes of 160–2,000 km, where they operate for about three months. They carry specialized experiment boxes that maintain optimal conditions for payloads, such as biotech experiments or material synthesis. Using advanced autonomy and material science, the vehicles navigate back to Earth, landing at designated points with precision. This capability is critical for industries like healthcare, where microgravity can enhance drug development, and materials science, where space conditions enable unique alloy formations.
Why Is Microgravity Research Critical for the Future?
Microgravity environments, nearly impossible to replicate on Earth, allow scientists to study phenomena like fluid dynamics, cell growth, and material properties without gravitational interference. With the ISS set to retire in 2030, the demand for alternative platforms is surging. Inbound Aerospace’s vehicles aim to fill this gap, offering cost-effective, repeatable, and safe payload return—a capability Aravind I B, CEO of Inbound Aerospace, calls “critical to unlocking the next wave of growth in the space economy.”
Who Are the Founders Behind Inbound Aerospace?
The founding team of Inbound Aerospace combines technical expertise and strategic vision:
- Aravind I B (CEO): A leader in deep-tech innovation, Aravind drives the startup’s mission to democratize microgravity research.
- Vishal Reddy: An expert in systems engineering, Vishal focuses on spacecraft design and subsystem validation.
- Capt (IN) Abhijit Bhutey (Retd): Bringing military precision and operational experience, Abhijit ensures mission reliability.
Their collaboration began at IIT Madras’ Nirmaan pre-incubation program, and the startup is now housed at the IIT Madras Incubation Cell, a hub for over 450 deep-tech startups valued at ₹50,000 crore.
How Will the $1 Million Funding Impact Inbound Aerospace’s Mission?
The $1 million funding will accelerate Inbound Aerospace’s research and development (R&D), focusing on:
- Subsystem Validation: Testing critical components like navigation and thermal protection systems.
- Critical Design Milestones: Finalizing designs for the first re-entry MVP mission by Q1 2028.
- Team Expansion: Hiring top talent to enhance autonomy and material science expertise.
Vishesh Rajaram, Managing Partner at Speciale Invest, emphasized, “Inbound’s deep-tech ambition spanning autonomy, material science, and systems engineering is bold and timely. We’re backing this team because they are not just thinking of access to space, but access back from space.” This funding marks Speciale Invest’s sixth space-tech investment, underscoring India’s growing role in the global space race.
What Makes IIT Madras a Hub for Space Tech Innovation?
IIT Madras has emerged as India’s leading deep-tech incubator, fostering startups like Agnikul Cosmos, GalaxEye, and now Inbound Aerospace. In 2025 alone, the institute incubated over 100 deep-tech startups, a historic first. Its Incubation Cell provides access to cutting-edge facilities, including a 38-meter drop tower for microgravity experiments, and collaborates with ISRO on projects like the Gaganyaan mission. The institute’s focus on aerospace engineering and interdisciplinary research makes it a breeding ground for space-tech innovation.
Startup INDIAX has closely followed IIT Madras’ rise as a space-tech powerhouse, spotlighting startups that leverage its ecosystem to push boundaries in aerospace and beyond.
How Does Inbound Aerospace Fit Into India’s Space Tech Ecosystem?
India’s space-tech sector is booming, with over 200 startups contributing to a market expected to reach ₹5,000 crore by 2030. The government’s Bio3E policy (2024) promotes biotech and pharma innovation in space, aligning with Inbound Aerospace’s focus on microgravity research. The startup’s selection as the only Indian finalist at Japan’s S-Booster 2025 competition highlights its global potential. By addressing the post-ISS gap, Inbound Aerospace is poised to lead India’s charge in commercial space manufacturing.
Real-life example: Similar to SpaceX’s reusable Falcon 9, Inbound Aerospace’s vehicles aim to reduce mission costs by up to 50%, making space research accessible to universities and small enterprises. This democratization is key to India’s vision of a sustainable orbital economy.
What’s Next for Inbound Aerospace and Its 2028 MVP Launch?
Inbound Aerospace plans to launch its first re-entry MVP mission by Q1 2028, a critical step toward commercializing its technology. The startup is already engaging with payload implementation partners, including universities and companies in biotech and materials science. The founders aim to raise a larger funding round before the test mission to scale operations and forge global partnerships. With India’s space sector attracting long-term capital post-ISRO’s success, Inbound Aerospace is well-positioned to shape the future of space-based R&D.
