An Indian Drone Startup Just Raised $37 Million to Deliver Packages by Flying Robot

Indian drone startup Airbound has raised $37 million in a funding round led by Greenoaks, with participation from DoorDash, Lachy Groom, Lightspeed, and Humba Ventures. The round closed less than a year after the company's $8.65 million seed round in October 2025, bringing total funding to nearly $50 million for the three-year-old company founded in 2023 by CEO Naman Pushp.

Airbound's current production drone, called TRT, weighs about 3.3 pounds and carries around 2.2 pounds of cargo. The next-generation version is expected to weigh about 6.6 pounds and carry up to 11 pounds of cargo, a fivefold increase in capacity. Both drones use a design called a tail-sitter. They take off and land standing upright on their tail, like a rocket, then tip forward and fly horizontally like an airplane. This lets them operate without a runway while still covering longer distances efficiently, since wings use less energy than spinning rotors for forward flight. The trade-off is that the moment when the drone transitions from vertical to horizontal flight requires sophisticated software to keep it stable.

The company has completed more than 13,000 autonomous flights across Bengaluru and Guntur in southern India. More than 1,000 of those flights were done with hospital network Narayana Health, transporting diagnostic samples like blood and tissue between facilities. On that route, Airbound covers roughly 2.5 miles in about seven minutes. The Narayana partnership is now expanding to include Narayana's newly opened Banashankari hospital in Bengaluru, which was designed without an on-site diagnostic lab or blood bank, making it dependent on drone-delivered samples from other facilities.

Beyond healthcare, Airbound signed an agreement with the Andhra Pradesh state government targeting 10,000 flights per day for retail, e-commerce, and healthcare deliveries. Reaching that pace will require between 250 and 1,000 aircraft, depending on route lengths. The agreement does not involve a government contract or subsidy; the state government is working with Airbound on the rules and permissions needed to operate the network at scale. TechCrunch

Airbound's seed round was led by Lachy Groom, co-founder of Physical Intelligence, and brought the company's total funding above $10 million at the time. Evertiq The jump to nearly $50 million in total funding within ten months reflects investor interest in drone delivery for markets where ground transportation is slowed by traffic, poor roads, or high costs for the final stretch of a delivery route.

The investor lineup is worth noting. Greenoaks leading the round signals confidence in the delivery business at scale. DoorDash's participation is more specific: a food-delivery and commerce platform backing a drone company that aims to handle retail and e-commerce cargo. That is a strategic investment, not a passive bet, and it connects Airbound with a potential customer already running large delivery networks in North America.

The tail-sitter design Airbound uses is not unique among drone companies, but the company's deployment strategy stands apart. The Narayana Health partnership, particularly the Banashankari hospital built without a lab, is an example of a building designed around drone delivery as its main way of moving samples, not as an extra convenience. When a hospital is planned without on-site diagnostics, drone transport becomes essential infrastructure, not a bonus.

The 10,000-flights-per-day target in Andhra Pradesh is ambitious. Even at the lower estimate of 250 aircraft, maintaining that pace requires high usage of each drone, reliable autonomous operations, regulatory cooperation, and maintenance schedules that keep the fleet flying. Airbound has completed thousands of flights so far, but scaling from hundreds of daily flights to five figures involves large increases in fleet management, airspace coordination, and the ability to handle failures gracefully. The regulatory work with the Andhra Pradesh government is still in progress, and the agreement carries no guaranteed revenue.

India's drone rules have evolved considerably since the liberalized Drone Rules of 2021 replaced an earlier, more restrictive framework. Airbound's ability to operate autonomously across two states and partner directly with a hospital network suggests the permissions exist for commercial drone flights beyond the operator's visual line of sight in at least some areas. The Andhra Pradesh agreement, if it leads to a functioning 10,000-flight network, would be among the larger autonomous drone delivery operations in the world.

The cost efficiency is also part of the story. Nearly $50 million raised over three years for a company building both the hardware and software for autonomous aircraft, operating real delivery routes, and preparing to scale to a fleet of up to 1,000 drones is modest compared to what companies in the broader autonomous-vehicle sector typically raise. The next drone version's jump to 11 pounds of cargo capacity puts Airbound in a weight class suitable for a wider range of medical, retail, and e-commerce deliveries, moving beyond diagnostic samples toward parcels and larger medical items.

The involvement of Lightspeed, which participated in both funding rounds, alongside Lachy Groom's continued backing, shows investor continuity from seed through Series A. The addition of Greenoaks and DoorDash at Series A broadens the base from early-stage venture capital to later-stage and strategic investors.

What Airbound is attempting, and what the funding enables, is the transition from demonstration routes to a commercially operated autonomous delivery network. The 13,000 flights completed to date establish operational credibility. The Andhra Pradesh target of 10,000 daily flights, the expanded Narayana Health partnership, and the next-generation aircraft with substantially higher cargo capacity together define the scope of what the $37 million is meant to finance.

The broader question is whether the regulatory framework, fleet reliability, and the economics of each delivery can come together fast enough to support that scale. The next 18 to 24 months will provide the answer.
