Inbound Aerospace eyes $10 million seed for reusable re-entry vehicle

By Amara Osei

Business Standard reported that Chennai-based space-tech startup Inbound Aerospace is discussing a $10 million seed round for its reusable re-entry vehicle. The report said the company is in talks with multiple investors, including existing investors Speciale Invest and Piper Serica, although the final target and structure remain unsettled.

Given the proposed round’s size, Business Standard said Inbound Aerospace expects to raise the money through a consortium. “Inbound is looking at the $10 million mark and is getting a good response,” a person aware of the developments said. The same source said the final fundraising target and structure were still under discussion.

What will the $10 million seed round fund?

Business Standard said the proceeds would primarily advance development of Inbound Aerospace’s reusable re-entry vehicle. The money will support testing and demonstration of the autonomous landing system before the company’s first actual mission in 2028.

Inbound Aerospace is developing thermal protection technology and improving flight-control systems, according to Business Standard. The report said those capabilities must enable the vehicle to withstand re-entry and land within a designated 100-metre radius.

Business Standard linked the financing to demonstrations of the autonomous parachute-based landing system. The report identified that system as a key component of the reusable vehicle and a capability for bringing payloads and experiments back from space.

How far has the landing system been tested?

Inbound Aerospace recently completed a one-kilometre drop test using a drone, Business Standard reported. The Chennai-based startup is preparing for an eight-kilometre drop test in the coming weeks, according to the report.

The test sequence gives the proposed round a defined engineering focus, according to Business Standard. It links a completed one-kilometre drone drop and a planned eight-kilometre test to an autonomous landing demonstration before the first actual mission in 2028.

Business Standard said the company aims to demonstrate that its vehicle can land less than 100 metres from a designated location after re-entry. It is developing the reusable vehicle to carry payloads into space and return them to Earth, the report said.

The first actual mission is targeted for 2028, Business Standard reported. Laboratory simulations indicate the possibility of reusing the vehicle eight to 10 times, according to the report.

Who is backing the seed round?

Existing investors Speciale Invest and Piper Serica are among the investors in discussion with Inbound Aerospace, according to Business Standard. The report said the consortium structure is expected because of the $10 million round’s size.

Inbound Aerospace was founded by Aravind I B, Abhijeet Bhutey and Vishal Reddy, Business Standard reported. The startup raised ₹9 crore in a pre-seed round last year, the report said.

IIT-Madras provided initial support worth ₹27 lakh to the startup, according to Business Standard. Inbound Aerospace was also incubated at the IIT Madras Research Park, the report said.

What role can autonomous parachutes play?

Business Standard said Inbound Aerospace is developing its autonomous parachute technology as a standalone product for the armed forces and disaster-relief agencies. The company has been named a provisional winner under the government’s Innovations for Defence Excellence (iDEX) programme, the report said.

Business Standard also reported discussions between the startup and the Air Force. It has held talks with the National Disaster Management Authority, according to the report, while the parachute system remains under development.

Which markets could adopt the platform?

The report identified pharmaceuticals, materials science and semiconductor research as potential applications for Inbound Aerospace’s re-entry platform. Business Standard said experiments conducted in microgravity could have commercial applications in those fields.

Inbound Aerospace is also discussing the platform with overseas organizations and payload developers in Singapore, Japan and the United Kingdom, according to Business Standard. The talks add international payload and research partners to the Air Force and National Disaster Management Authority discussions already under way.

For investors, the coming-weeks eight-kilometre drop test is the next concrete technical checkpoint. The $10 million target and consortium structure remain unsettled, while the 2028 mission and laboratory estimate of eight to 10 uses still require further demonstration.
