How Momentus Makes Money

Momentus is a U.S. commercial space company that offers in-space infrastructure services, including in-space transportation, hosted payloads and in-orbit services. The company represents an ambitious venture into the burgeoning space economy, though its path to profitability remains uncertain in a capital-intensive industry.

How It Started

The company gained early venture backing through Y Combinator and Prime Movers Lab based on its concept of a “space tug” that would transport small satellites from drop-off orbits provided by heavy-lift rockets to custom operational orbits using low-cost water plasma propulsion. This U.S. commercial space firm is a key player in orbital services, specializing in satellite transportation using its innovative water plasma propulsion technology. The target audience includes satellite operators, space agencies and commercial space entities, all seeking cost-effective and flexible solutions for deploying spacecraft to precise orbital locations.

Competitive Advantage

Momentus possesses several distinct competitive strengths that differentiate it in the crowded space economy:

Proprietary Water Plasma Propulsion: The system uses solar arrays to power a microwave emitter, which turns liquid water propellant into superheated plasma. Water is utilized because it is non-toxic, easily stored without high-pressure cryogenic tanks and presents a theoretical pathway for future in-situ resource utilization via asteroid or lunar ice mining.
Cost Efficiency: Water is cheaper, safer and more environmentally friendly than traditional chemical propellants, which should lead to better unit economics over time.
Government Validation: In January 2026, Momentus was selected as a qualified vendor for the Missile Defense Agency (MDA) SHIELD program, a multi-award contract vehicle with a $151 billion ceiling over ten years.
Vigoride Platform: Modern iterations of the Vigoride bus are capable of generating up to 3 kilowatts of peak solar power to support compute-heavy military sensors and robotic payloads.

Marketing Techniques

Momentus employs multiple marketing and business development channels to reach its audience:

Government Contracts and Partnerships: The company actively pursues defense and space agency contracts. Momentus was selected to participate in the U.S. Missile Defense Agency’s Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) contract vehicle.
Commercial Partnerships: The company describes a contract with DPhi Space to fly an edge computing payload, Clustergate-2, on a Vigoride mission. This payload is intended to enable deployment and operation of software applications in orbit, including AI algorithms, by using a hosted payload model on a shared satellite equipped with high-performance edge computing hardware.
Strategic Technology Collaborations: Momentus reports collaborating with Velo3D on an additively manufactured fuel tank to be flight tested on a Vigoride mission.
Multi-Year Agreements: The company recently secured a $15 million global agreement with Solstar Space and a $7.0 million warrant inducement transaction in October 2025 to support operations.

The company’s business model is multi-faceted, encompassing three main services: Space Transportation, Satellite as a Service and In-Orbit Servicing. The company generally prices its Vigoride transportation service at roughly $15,000 per kilogram of payload, though the final price depends on the specific orbital requirements and mission complexity. Revenue from deploying customer satellites and hosting experiments on their Vigoride vehicles represents around 35% of total revenue. The Q3 2025 service revenue of $234,000 shows an uptick from the prior quarter, suggesting some stabilization in their core service delivery.

Business Model Canvas of Momentus

The Business Model Canvas for Momentus reveals a company structured around the following key components:

Value Proposition: To increase deployment options for satellite operators and lower their operating costs relative to traditional approaches, while also minimizing environmental impact through the use of water as a propellant.
Key Partners: Strategic partnerships with launch providers integrate Momentus Space’s Vigoride transfer vehicles with rockets to ensure a seamless transition from launch to orbital deployment.
Revenue Streams: The revenue model is based on a combination of per-service fees, long-term contracts and strategic partnerships. The primary revenue stream comes from service fees charged per kilogram of transported payload, which vary depending on the complexity and distance of orbital transfer. Additionally, Momentus secures multi-year agreements with satellite operators and space agencies that provide a stable and recurring revenue base.
Customer Segments: Customers range from small satellite operators to larger enterprises and government organizations that select services tailored to their specific needs.

Conclusion: Is It a Viable Business?

Momentus presents a compelling long-term opportunity tempered by substantial near-term risks. Management acknowledges going-concern risks, which it aims to mitigate through planned capital-raising efforts. While the company possesses innovative technology and valuable government contracts, the business model is a fixed-cost, high-leverage play, meaning a massive increase in mission volume is required to turn a profit. The company’s recent SHIELD contract selection suggests strong potential for government-funded growth, yet profitability depends critically on scaling operations and securing recurring mission volumes. For risk-averse investors, Momentus remains highly speculative; for those betting on the expansion of the space economy, it offers meaningful upside potential if execution improves.
