Presenting: Leyden Space - Propellantless Electromagnetic Propulsion
Details
Leyden Space (http://leydenspace.org) – Founder Ashle Jantzen presenting, is developing next-generation satellite propulsion systems that enable longer missions and safer spacecraft operation.
Leyden Space is building propellant-less satellite propulsion that enables real-time attitude adjustment for collision avoidance and long-term mission extension. This technology uses plasma propulsion principles to offer continuous, frictionless movement in space, reducing the risk of orbital debris and increasing operational lifespan. Unlike traditional propulsion methods, our system is scalable, lightweight, and eliminates dependency on onboard fuel reserves, making it ideal for commercial and government space missions focused on long-term orbital presence and safety.
Our target market is commercial satellite operators and space agencies in the US who need cost-effective, long-duration orbital control solutions & are willing to pay for increased mission life and safety assurance.
Our competition is traditional chemical thrusters, cold gas propulsion, and electrospray thrusters. Our competitive advantage is propellant-less, fuel-free maneuvering that reduces launch mass, extends operational lifespan, and enhances collision avoidance.
The total market size in 2024 for satellite propulsion systems is estimated at $8.4B, with a projected annual revenue opportunity of $1.2B for long-duration orbital control technologies.
Top 3 challenges:
- Proving minimum viable product viability within 6 years
- Raising funding for R&D and early pilots
- Building stronger connections within the aerospace investment ecosystem
Our Pitch Boulder ask: We're looking for feedback on our business model, investment pitch, and GTM clarity. What red flags would stop an early-stage investor? Are there better ways to communicate this vision to angels and strategic aerospace partners?
