Trishul Space Raises ₹4 Crore in Pre-Seed Funding Round led by IAN Angel Fund
New Delhi, November 10, 2025 — Trishul Space, an advanced rocket propulsion startup developing next-generation liquid rocket engines, has secured ₹4 crore in a pre-seed funding round led by the IAN Angel Fund, with participation from 8X Ventures and ITEL. The capital will fund research and testing of advanced turbopump technology, accelerating the development and commercialization of Harpy-1, a high-performance liquid rocket engine for small satellite launch vehicles.
Founded 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 one of the toughest challenges for launch vehicle developers. The process is expensive, time-consuming, and technically complex, often creating a major bottleneck in the space industry. Trishul Space aims to solve this by developing cost-effective, ready-to-use liquid rocket engines that cut down development time, complexity, and cost, targeting 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.
India’s space sector is shifting from government-led programs to a vibrant private ecosystem. Trishul Space aims to make rocket propulsion more modular and accessible, helping new players build faster and cheaper without starting from scratch, through its modular, plug-and-play reliable system.
By delivering advanced, affordable propulsion solutions, Trishul accelerates development timelines and lowers entry barriers for new and emerging space players. It is strategically positioned in the global small and medium launch vehicle market, projected to cross USD 15 billion by 2030, where propulsion systems account for nearly 30–40 percent of total launch costs.
The IAN Angel Fund’s investment reflects strong investor confidence in India’s space ecosystem and aligns with its focus on deep-tech ventures that help build for India’s strategic imperatives.
