b. a. D-Propulse founded in 2025 by CEO Saurav Jha and CTO V. Ramanujachari in New Delhi, India, D-Propulse develops aerospace propulsion solutions centered on its Rotating Detonation Engine (RDE).

In January 2026, D-Propulse raised INR 250 million in venture funding from IAN Alpha Fund, an IAN Group’s VC fund. D-Propulse specializes in the development of advanced propulsion technologies, primarily centered around its flagship product, the Rotating Detonation Engine (RDE). This engine is designed to be mechanically simple yet thermodynamically superior, enabling affordable hypersonic flight. By delivering enhanced thrust with reduced mass, the RDE aims to transform aerospace capabilities for defense and space access.

The company primarily targets national defense agencies, aerospace manufacturers, and government organizations requiring advanced propulsion solutions for high-speed platforms. D-Propulse's offerings are positioned in various geographical markets including North America, Europe, and Asia, where the demand for innovative aerospace technologies is growing. D-Propulse generates revenue through B2B partnerships and contracts with government and defense entities, focusing on the commercialization of its RDE technology. The transaction structure typically involves tailored agreements that outline the development and delivery of propulsion systems for specific defense applications, ensuring compliance with strict performance requirements.

Revenue is derived from milestone payments associated with the development phases of products, as well as ongoing support and maintenance services for deployed systems. The financial model emphasizes long-term contracts that may include provisions for future upgrades and enhancements, thereby securing ongoing revenue streams as clients integrate D-Propulse's technologies into their aerospace operations. In January 2026, D-Propulse raised INR 250 million in venture funding from IAN Alpha Fund, an IAN Group’s VC fund. The company plans to use the January 2026 funding to expand the engineering team, strengthen computing and simulation capabilities, and set up limited testing infrastructure.

The company is also integrating AI into both operations and technical development to accelerate design and validation cycles. Initial engagements with the Indian military are underway, with export markets to be addressed in close consultation with the government at a later stage.
