The Chennai-based area startup is actually reaching for the celebs. In Could, it took an enormous step in that route, efficiently test-launching its single-piece 3D printed semi-cryogenic rocket. Referred to as Agnibaan–SOrTeD (suborbital technological demonstrator), the rocket was launched from the Indian Area Analysis Organisation’s (ISRO) Satish Dhawan Area Centre at Sriharikota.
It was the startup’s first check flight, and demonstrated its homegrown expertise. The check run additionally gathered essential flight information for Agnikul’s orbital launch automobile, the Agnibaan.
The corporate used an industrial 3D printer to make the semi-cryogenic rocket engine as “a single piece in lower than every week—proper from the place the place the gas enters the engine, until the exhaust and nozzle,” Srinath Ravichandran, Agnikul’s co-founder and CEO, instructed Mint.
3D printing, also referred to as additive manufacturing, fabricates complicated objects by depositing supplies layer by layer. Uncooked supplies are fed into the 3D printer for the machine to provide the specified half. Agnikul makes use of Inconel 718, a high-temperature aerospace alloy, to make its rocket engines.
The check flight passed off from one other piece of engineering designed by Agnikul’s staff: India’s first non-public cellular launchpad. Referred to as Dhanush, the cellular launchpad permits the corporate the pliability to launch a rocket from any location. Having tasted success, Agnikul now needs to unravel the small-satellite drawback by launching “on-demand rockets” from numerous world places with its cellular launchpad, and having them “in orbit inside two weeks of signing a contract”.

At present, many small satellites share rides on bigger rockets. The founders hope that Agnibaan would be the automobile of selection for entities seeking to launch such small payloads into area. “Agnibaan may be configured to accommodate payloads ranging between 30kg and 300kg. Therefore, anybody with lower than 300kg is our audience,” stated Srinath.
The important thing drawback isn’t price however the ready interval, stated the Agnikul co-founder. He defined {that a} typical rocket engine contains many elements, together with a combustion chamber, custom-made spark plug, an injector, cooling system, copper tubes, nozzles and ignitors, all of which have to be welded, fixed or screwed collectively. This can be a problem by way of time and high quality consistency, and usually takes 16-18 weeks to construct from scratch. A “single-piece” rocket engine, however, is an on-demand choice that may be inbuilt simply three days.
“We goal to create rockets that may be simply configured primarily based on the satellite tv for pc’s dimension and vacation spot,” stated Srinath. The rockets, he stated, will likely be “configurable”, implying that Agnikul can improve or cut back the variety of engines, relying on the load of the satellites it’s carrying.
Eye on the pie

In doing all this, Agnikul goals to seize a small slice of the large world area expertise market. The market was value $443.20 billion in 2023 and is forecast to the touch about $916.85 billion by 2033, spurred by the rising demand for satellite tv for pc companies throughout numerous industries, based on Priority Analysis. India, although, is estimated to have only a miniscule 2% share of the market.
The excellent news is that the Indian area financial system has the potential to achieve $44 billion within the subsequent 10 years from the present $8.4 billion, based on India’s area promotion company, IN-SPACe, “increasing India’s share of the worldwide area financial system by 4x from the present 2% to eight%”.
The area market is very aggressive, and contains world area businesses comparable to NASA and ISRO, in addition to firms that make rockets and spacecraft, comparable to SpaceX, Blue Origin, Airbus, Boeing, and Lockheed Martin Area Techniques.
In India, other than ISRO, there are different Indian aerospace firms and basic engineering firms vying with one another, comparable to Larsen and Toubro, Bharat Forge, and Bharat Electronics. As well as, there are 200 or so homegrown area startups, together with Agnikul, Skyroot Aerospace, Pixxel, SatSure, Dhruva Area, and Bellatrix Aerospace, seeking to get a foot within the door. These startups started flourishing after the approval of the Indian Area Coverage, 2023, which gave a significant impetus to the non-public area business, making it a profitable funding choice for buyers.
The federal government additionally arrange the Indian Nationwide Area Promotion and Authorization Centre (IN-SPACe) as a single-window autonomous company to advertise and authorize area actions, appointing former Mahindra and Mahindra managing director Pawan Goenka as its chairman. IN-SPACe performs a vital function as a facilitator between ISRO and personal sector firms. The federal government’s determination to arrange a ₹1,000 crore fund for area startups, which was introduced in July’s union finances, is predicted to increase India’s presence within the world area market.
As Agnikul gears as much as get a chunk of the motion, we check out the rocket maker’s journey, the individuals who have been part of it, and what comes subsequent for the corporate.
Pursuing a dream
Srinath grew up in an setting the place there have been a whole lot of conversations round science—his mom was a Physics trainer and his father, a civil engineer. In 2001, he received a possibility to go to ISRO, which was choosing scholar scientists from India for the Nationwide Aeronautics and Area Administration (NASA)’s ‘Mars Surveyor Mission’. Srinath didn’t get chosen within the finals, however “I received to the touch a satellite tv for pc for the primary time”, he recalled.

When it got here time for Srinath to decide on a area of examine for his bachelor’s diploma, nevertheless, his household opposed a profession in aerospace because of the restricted job alternatives in India exterior of ISRO. And so, he pursued electrical engineering on the School of Engineering, Guindy (Chennai), graduating in 2006. He then labored at world engineering large ABB, commissioning drives for blast furnaces in metal crops, however discovered the function unfulfilling.
Subsequent, he enrolled for a one-year Grasp’s programme in Monetary Engineering (combining finance and engineering) at Columbia College in 2009. This era coincided with the monetary disaster, making job looking difficult. Nonetheless, he secured a place at funding supervisor AXA, working in portfolio administration and threat modelling. Over time, he superior from being a quant to a dealer, and at last, a portfolio supervisor. Nevertheless, his ardour for engineering, significantly aerospace, by no means waned.
The rise of SpaceX within the US reignited Srinath’s aspirations for a profession in aerospace. In 2015, following SpaceX’s profitable restoration of a booster, he determined to depart his job and pursue the dream. Srinath utilized for a second grasp’s diploma, this time in aerospace engineering, on the College of Illinois, “however I didn’t full it”.
In 2016, he conceived the concept of constructing small rockets to satisfy the wants of recent, smaller satellites, which massive, conventional rockets couldn’t adequately serve. The next 12 months, he moved again to India and co-founded Agnikul along with his buddy Moin SPM, who’s now co-founder and COO of the startup.

“Srinath and I knew one another from our ‘gully cricket’ days, and evenings spent in pubs with our mates, the place each of us mentioned concepts since we don’t drink,” recalled Moin. His story is equally fascinating.
Moin graduated in aeronautical engineering in 2011, following which he went to Australia to do his MBA, with specialization in aviation administration. When he returned to India, he began a producing cosmetics firm. “We began with our personal model, and grew to turn out to be a contract producer for some greater manufacturers as effectively. We generated sufficient income out of it, and noticed some revenue too,” he recalled. However his coronary heart was not in his firm, so “I gave it to different relations” and joined Srinath.
Prelude to the launch
Satyanarayanan R. Chakravarthy, a professor at IIT Madras and knowledgeable on stable propellant rockets, performed a vital function in mentoring Srinath and Moin. The duo approached him via a number of contacts in the summertime of 2017 and sought steerage on constructing rockets. “Our discussions initially revolved round selecting between stable and liquid rockets,” recalled the professor.
Cheaper to construct, stable rockets burn pre-mixed propellants (gas and a supply of oxygen, referred to as an oxidiser) in a cylinder to maneuver the plane via the air (thrust). As soon as the burning course of begins, it can’t be stopped. Liquid rockets retailer the propellants in separate chambers, and pump them into the combustion chamber to provide thrust. This separation permits the method to be adjusted or stopped if there’s a drawback.

Agnikul, which selected the liquid route, formally included in December 2017. Chakravarty launched Srinath and Moin to Ravi Perumal, a former ISRO director and Padma Bhushan recipient, whose “experience offered invaluable insights”. They started by brainstorming rocket configurations—the variety of phases, payload capability, focused orbits, and market potential. “Over two-three months, we explored about 50 totally different configurations,” stated Chakravarty. Inside six months, they “converged on a three-stage rocket design and embraced 3D printing, impressed by world pioneers like Rocket Lab and Relativity Area”.
In September 2018, Agnikul efficiently fired the primary small engine, referred to as ‘Agnilet’, an achievement that attracted the eye of buyers, resulting in a seed spherical of $500,000. Subsequent funding rounds have taken its whole funding to about $42 million. Agnikul’s buyers embody Mayfield, Celesta Capital, Speciale Make investments, pi Ventures, and Artha Enterprise Fund, together with outstanding angel buyers, comparable to Anand Mahindra and Nithin Kamath.
Vishesh Rajaram, founder and managing accomplice at Speciale Make investments, recalled that his journey with Agnikul started via an interplay facilitated by The Indus Entrepreneurs (TiE), Chennai. “It’s right here that we met Srinath and Moin. Their imaginative and prescient was clear and superior for the time. They acknowledged the necessity for a launch automobile that may very well be quickly produced to satisfy the calls for of the rising small satellite tv for pc market,” he recalled.
The startup at present has over 200 workers, of which a few third are girls, together with 30-year-old Saranya Periaswamy, vice chairman of buildings and aerodynamics, and 27-year-old Uma Maheshwari, affiliate director of engineering.
“As automobile director, I oversee the complete course of from design to manufacturing, guaranteeing seamless integration with the launchpad. My staff contains 26 engineers,” stated Saranya.

Maheshwari, who joined Agnikul via a campus interview, leads the propulsion and instrumentation software program groups, comprising about 35 engineers. She was challenge director of the Agnibaan–SOrTeD mission. “Whereas Saranya was the automobile director for the mission, I used to be answerable for getting the automobile prepared,” she stated, satisfaction writ massive over her face.
Competitors heating up
Whereas Agnikul is at present specializing in small satellites, it’s a section different area startups are additionally eyeing. Hyderabad-headquartered Skyroot Aerospace, as an illustration, efficiently launched India’s and South Asia’s first privately-developed rocket, Vikram-S, in November 2022.
“Skyroot’s Vikram-1 small satellite tv for pc launcher is modular, and is able to carrying satellite tv for pc payloads starting from 200-800 kg. We are going to largely goal the decrease orbits, which can also be the place a lot of the demand is,” stated Pawan Kumar Chandana, the corporate’s CEO and co-founder.

Skyroot, which was based by Chandana and Naga Bharath Daka, each former ISRO engineers, has raised essentially the most funding ($95 million) amongst Indian area startups until date. Provided that area is capex intensive, this offers it a bonus.
Chandana famous that final April, Skyroot, too, had test-fired its 3D-printed Dhawan II cryogenic engine. “One of many engine phases is 3D-printed. This helps us obtain scalability for our on-demand rocket launch mannequin. For the higher booster stage, we use carbon fibre within the engine to cut back weight and maximize effectivity,” he stated.
Nevertheless, Skryoot selected to not construct a single-piece 3D-printed engine as a result of it “offers us the benefit of having the ability to restore and repair any a part of the engine in case of a fault”. In totally 3D-printed engines, he argues, “the entire engine must be made out of scratch in case of an error”.
Chakravarthy disagrees with this view. “We’ve a pedigree of getting examined this totally built-in 3D printed rocket engine 10 instances over,” he stated, including, “Fortuitously for us, the launch, too, was a hit as a result of only a few rockets succeed of their maiden flight.”
One of many engine phases is 3D-printed. This helps us obtain scalability for our on-demand rocket launch mannequin.

Agnikul, nevertheless, received the launch proper solely on its fourth try. The sooner makes an attempt—on 22 March, 6 April and seven April—needed to be referred to as off attributable to technical difficulties. “They have been makes an attempt—the mission didn’t fail. The rocket didn’t depart the launchpad. So, our first flight was truly a hit,” Chakravarty insisted.
That stated, many firms use 3D printing for area elements and even rockets as we speak. In 2017, US-based Rocket Lab’s Electron rocket was powered by a 3D engine. 4 years later, US-based Relativity Area efficiently launched an “nearly completely 3D printed” rocket referred to as Terran 1, although it failed to achieve orbit. In India, ISRO efficiently examined a 3D printed liquid rocket engine in early Could.
Going business
“We’ve managed to get the tech proper. Now, we’re readying for commercialization and are trying on the subsequent launch someplace across the first or second quarter of calendar 12 months 2025,” stated Srinath. “We’ve letters of intent with about 9 clients to this point and are speaking to 40-50 different clients for the following few launches.”
These clients, he added, with out naming any for confidentiality causes, are throughout sectors—most of them are within the communication area, whereas some are in logistics and telecom. “Merely put, anybody who needs to place small satellites in orbit to allow some type of communication may be our buyer,” stated the co-founder.
Chaitanya Giri, area guide and affiliate professor at Pune’s Flame College, stated that there isn’t a one set method to success, and all small satellite tv for pc launch service suppliers are in search of methods to maximise the effectivity of their rockets.
“Greater than competing in opposition to SpaceX, it’s about looking for addressable market areas. Ultimately, that is what is going to give India’s space-launch firms a distinct segment to serve,” stated Giri. “Agnikul Cosmos has its strengths. It now wants a clean second launch to make a greater business case for itself.”
