Prayagraj-based advanced rocket propulsion startup Trishul Space raises Rs 4 crore funding

Trishul Space, an advanced rocket propulsion startup developing next-generation liquid rocket engines, has raised Rs 4 crore in a pre-seed funding round led by the IAN Angel Fund, with participation from 8X Ventures and ITEL.

The startup will use the raised captial to fund research and testing of advanced turbopump technology, accelerating the development and commercialization of Harpy-1, a liquid rocket engine for small satellite launch vehicles. 

Founded in 2022 by Aditya Singh, Divyam, and Rajat Choudhary, Trishul Space builds high-performance propulsion systems powered by staged combustion cycles and AI-driven failure detection mechanism. 

Building rocket engines is among the toughest challenges for launch vehicle developers because the process is costly, time-consuming, and technically complex. Trishul Space aims to address this bottleneck by creating cost-effective, ready-to-use liquid rocket engines intended to reduce development time, complexity, and cost for both private and government launch vehicle manufacturers.

Rajat Choudhary, Co-founder, Trishul Space, said, “This investment is a strong validation of our vision to build India’s most advanced and reliable rocket propulsion systems. With this support, we aim to accelerate the development and testing of our ‘Harpy-1’ engine, strengthen India’s space launch ecosystem, and move one step closer to making space access faster, affordable, and globally competitive. In addition, IAN’s mentoring and guidance would help us build valuable business.” 

India’s space sector is shifting from government-led programs to a fast-growing private ecosystem. Trishul Space aims to make rocket propulsion more modular and accessible through a plug-and-play system that helps new entrants build faster and at lower cost without starting from scratch.

By delivering advanced and affordable propulsion solutions, the startup said it can shorten development timelines and lower entry barriers for emerging space players. It is targeting the global small- and medium-lift launch vehicle market, which is projected to exceed $15 billion by 2030, with propulsion systems accounting for 30% to 40% of total launch costs.

Trishul Space has its headquarters in Prayagraj, Uttar Pradesh, and operates out of IIT Delhi’s R&I Park.
