Company profile

researched Aug 2026

Epic Aerospace is an aerospace company headquartered in Buenos Aires, Argentina that manufactures and operates orbit transfer vehicles (OTVs), also called space tugs, for in-space transportation of satellites. The company positions its vehicles as "last-mile delivery for satellites": customers buy a slot on a common rideshare launch, and the OTV then carries the payload from the launch vehicle's drop-off orbit to its intended destination, spanning low Earth orbit, geostationary orbit and beyond. Its stated longer-term aim is a network of space tugs providing mobility infrastructure that would allow satellites to move freely and be upgraded once in space.

The company is vertically integrated across propulsion, structures and avionics. Its catalogued propulsion products include a 900N apogee thruster running on 95% high test peroxide (HTP) and kerosene with 310s vacuum specific impulse, 14 bar feed pressure and 270 kg propellant throughput, and a 1N cold-gas thruster pack using nitrogen or helium with 50s or 150s vacuum Isp, 26 bar feed pressure and a sub-60 ms minimum pulse. Epic also produces, stores and exports highly concentrated hydrogen peroxide, upgrading commercial or research grade 60% stock to 95% or 98% concentrations, optionally compliant with "Mil-Spec E" specifications, and offers it at $45/kg (95%) and $65/kg (98%) with a 280 kg minimum order.

Beyond orbital delivery, Epic markets end-to-end mission support, offering its infrastructure and technology to customers from satellite design through operation in space. It operates factories in two countries, each with clean rooms, office space and integration facilities; one is co-located with its test site and HTP production, with in-house machining and welding, while the second sits in a tax-free zone suited to import and export operations and to leveraging space-rated hardware from international partners.

Founding story

Founder Ignacio Alejandro Belieres Montero started Epic Aerospace after dropping out of Stanford University; he was 21 at the time of a January 2020 Forbes profile. Forbes framed the company against the high cost of entry to commercial space activity and quoted Montero: "My overall goal is to build a transport network in space. Soon, anyone will be able to launch a satellite into space. At Epic Aerospace, we want to build the physical layer for a network of satellites in space." His recruiting drew a small team with substantial Argentinian aerospace experience.

Business model

B2B hardware and services: Epic Aerospace sells in-space transportation on its orbit transfer vehicles to satellite operators launching on shared rideshare missions, and also markets its underlying vertically integrated capabilities directly — propulsion systems (a 900N HTP/kerosene apogee thruster and a 1N cold-gas reaction control thruster pack, both priced on inquiry), high test peroxide propellant sold by the kilogram with a 280 kg minimum order, and contract manufacturing of valves, feed systems, structures and complete satellites. Caplight characterizes the customer profile as government contracts, services and consulting, and hardware sales.

Revenue is generated from in-space transportation missions carrying customer satellites to target orbits, sales of propulsion hardware such as apogee and cold-gas thrusters priced on inquiry, sales of 95% and 98% high test peroxide propellant priced per kilogram with shipping and fueling operations quoted separately, and contract manufacturing and end-to-end mission support services.

Traction

The company launched its first orbit transfer vehicle, CHIMERA LEO 1, on the SpaceX Transporter 6 mission and states it is in orbit. Y Combinator lists a team size of 14 and active status; Caplight lists an employee figure of 31 and total funding raised of $250,000. In January 2020, Forbes reported a twelve-person team with over thirty-five years of collective aerospace industry experience covering 200 engine tests, three medium-size launch vehicles and two Argentinian flagship satellites.

Latest developments

Epic Aerospace's first orbit transfer vehicle, CHIMERA LEO 1, launched aboard the SpaceX Transporter 6 mission and the company reports it is in orbit, describing the flight as a first step toward commercializing its in-space transportation services. The company publishes a catalogue of propulsion products and HTP propellant pricing and continues to advertise its two-country factory footprint. Y Combinator lists the company as active with a team of 14.

Full profile — market position, technology, go-to-market, geography, history

Market position

Epic Aerospace competes in the emerging orbital transfer/space tug segment. Forbes cited an estimated geostationary insertion market of roughly $3.1 billion and named Atomos and fellow YC-backed Momentus — which had partnership agreements with SpaceX and Relativity Space — as other entrants. Caplight classifies the company under Frontier & Industrial Tech with space technology and alternative fuels verticals and lists Space Machines Company and PAVE Space as comparables.

Epic Aerospace describes itself as a fully vertically integrated propulsion developer and manufacturer, covering injector and thrust chamber assembly design, testing, qualification and delivery of complete propulsion systems with heritage-component-based feed systems, with a specialty in non-toxic hypergolic propellants using both liquid-liquid injectors and catalyst beds. It also states it is unique in being able to produce, store and export highly concentrated hydrogen peroxide for rocket engine use, and it pairs manufacturing co-located with its own test site and HTP production with a second facility in a tax-free zone for import/export and on-demand capacity expansion.

Technology

The core technology is a line of chemical-propelled orbit transfer vehicles, beginning with CHIMERA LEO 1. Propulsion centers on non-toxic hypergolic propellants and high test peroxide: a 900N apogee thruster burning 95% HTP with kerosene at 310s vacuum Isp, 14 bar feed pressure and 270 kg throughput, and a 1N cold-gas thruster pack using nitrogen or helium (50s or 150s vacuum Isp, 26 bar feed pressure, minimum pulse under 60 ms). The company designs injectors and thrust chamber assemblies, uses both liquid-liquid injectors and catalyst beds, and builds heritage-component-based feed systems. It also concentrates hydrogen peroxide from 60% stock to 95% or 98% stabilized HTP, and manufactures valves, feed systems, structures and complete satellites in facilities with 800 m2 of usable space, an 80 m2 clean room, 150 m2 of office area and machine shop equipment including a 4-axis CNC mill and lathes. Forbes reported in 2020 that the tugs were designed to be reusable, docking with satellites and repositioning them in LEO before extending the approach to GEO, refueling and repeating the process.

Go-to-market

The company sells directly to satellite operators and mission customers, with propulsion systems and fueling operations quoted on an inquiry basis and HTP propellant listed at published per-kilogram prices plus estimated shipping of $3,500 to $8,500. Its first flight on SpaceX's Transporter 6 rideshare mission serves as a demonstration for commercializing its in-space transportation services, and it offers end-to-end engineering support for complex missions as an additional entry point.

Small satellite operators and manufacturers that launch on shared rideshare vehicles and need precise orbital deployment to LEO, GEO or beyond; customers of propulsion systems and high test peroxide propellant; and organizations needing design-to-operations support for complex satellite missions. Caplight identifies government contracts, services and consulting, and hardware sales as customer types.

Geography

Headquartered in Buenos Aires, Argentina (José A. Cabrera 5653, CABA, C1414), with additional listed locations in Florida, USA (EPIC PPF) and Montevideo, Uruguay (Ruta 8 km 17.500, Zonamerica). The company states it has factories in two countries, one co-located with its test site and HTP production facilities and one in a tax-free zone oriented to import and export. In January 2020 Forbes described the company as San Francisco- and Buenos Aires-based.

History

Founded in 2017 according to Caplight firmographic data, the company took part in Y Combinator's Summer 2019 batch and had closed a seed round by early 2020, when Forbes described it as a San Francisco- and Buenos Aires-based team of twelve with combined experience spanning 200 engine tests, three medium-size launch vehicles and two Argentinian flagship satellites. A further round recorded as a grant is dated December 2020. The company's first orbit transfer vehicle, CHIMERA LEO 1, was launched on the SpaceX Transporter 6 mission, and the company states it is in orbit. Y Combinator lists the company as active with a team size of 14.
