The New Space Race: 30 Emerging Space-Tech Companies to Watch for in 2027
Space is no longer the exclusive domain of national agencies and a handful of legacy technology majors. Over the last 5-6 years, a new generation of venture-backed companies have emerged to build the infrastructure layer of the orbital economy - satellite manufacturing at scale, in-space mobility and logistics, debris removal, orbital manufacturing, space-based computing, and next-generation propulsion.
Much of this is being driven by three converging forces - a) falling launch costs (thanks to reusable rockets), a sharp rise in defense and national-security space spending (European “space sovereignty”, b) NATO's push for resilient constellations and push for sovereign satellite capability among emerging nations), and c) the arrival of AI compute demand that is now spilling over from terrestrial data centers into orbit.
Below we discuss 30 companies in this space that are making a difference and have a unique differentiator that makes them a high growth prospect for the coming years.
1. Neuraspace
Founded: 2020
HQ: Coimbra / Lisbon, Portugal
Neuraspace builds AI-powered space traffic management and collision-avoidance solution - essentially "air traffic control" for satellites. Neuraspace raised €15.6 million in mid-2026, on top of an earlier €2.5 million round, after reporting 350%+ revenue growth in a year. Customers span ESA, NATO, the Portuguese Air Force, and commercial operators like Spire Global.
As satellite counts explode, AI-driven autonomous collision prediction will become essential infrastructure, meaning, Neuraspace's dual-use (civil + defense) platform, NeuraspaceDEF, positions it well for Europe's growing defense-space budgets and sovereign ambition.
2. Apex Space
Founded: 2022
HQ: Los Angeles, US
Apex makes "productised" off-the-shelf satellite buses - standardised platforms customers configure rather than custom-build - cutting spacecraft lead times dramatically. It has raised $718 million+ total, hitting unicorn status with a $1 billion+ valuation in September 2025 and then doubling to a $2.3 billion valuation in June 2026 on a $200 million raise.
Apex is a collaborator with Northrop Grumman on the Golden Dome missile-defense interceptor program and counts "nearly every major defense prime" as a customer. Its mass-production approach is meant to solve the satellite “bottleneck” for DoD and commercial constellations. It also teamed with tech giants like Amazon (for Amazon’s Project Kuiper) in 2026. In short, highly-verticalised manufacturing and huge VC backing make Apex a rising star in high-volume spacecraft.
3. Impulse Space
Founded: 2021
HQ: Redondo Beach, US
Impulse builds in-space "last mile" transportation - the Mira maneuvering spacecraft (three successful flights) and the Helios high-energy kick stage (first flight in 2027) that moves payloads from LEO to GEO, cislunar space and beyond, in hours instead of months. It closed a $500 million Series D at a ~$4.26 billion valuation in June 2026, pushing total funding past $1 billion.
Impulse is supporting Anduril on the Space Force's Golden Dome program and has 30+ customer contracts worth nearly $200 million. As launch becomes commoditised, the bottleneck shifts to "what happens after separation" - Impulse is building that layer.
4. K2 Space
Founded: 2022
HQ: Torrance, US
K2 takes the contrarian bet that satellites should get bigger, not smaller, to exploit heavy-lift rockets like Starship and New Glenn. Its "Mega Class" satellites deliver ~10x the power of comparable platforms. Funding has escalated fast: $50 million Series A (2024) → $110 million Series B (Feb 2025) → $250 million Series C at a $3 billion valuation (Dec 2025) → $500 million Series D at a $6.8 billion valuation (July 2026).
By focusing on large GEO-capable buses and quick turnaround (vs. do-it-all startups), K2 is positioned for military and mega-constellation demand.
5. Varda Space Industries
Founded: 2020
HQ: El Segundo, US
Varda manufactures pharmaceuticals in microgravity aboard autonomous capsules that reenter and return the product to Earth - the first company to process materials outside the ISS. It has raised $329 million total (last valued around $500 million+), including a $187 million Series C in mid-2025.
Varda is attracting DoD interest by demonstrating reusable reentry tech (e.g. hypersonic test payloads). As one of the few companies regularly returning cargo from orbit, Varda is a standout for in-space factory growth.
6. True Anomaly
Founded: 2022
HQ: Centennial, Colorado, US
True Anomaly is a pure-play orbital-defense startup - no commercial hedge. Its Jackal autonomous orbital vehicle performs rendezvous and proximity operations; its Mosaic software provides mission autonomy. Funding has roughly tripled each round: $17 million Series A → $100 million Series B → $260 million Series C → $650 million Series D at a $2.2 billion valuation (April 2026).
True Anomaly was selected as one of 12 companies for the Pentagon's Golden Dome space-based-interceptor program (up to $3.2 billion in prototype contracts) and the $1.8 billion Andromeda GEO surveillance program. The company sits at the center of the fastest-growing pocket of space spending - national security.
7. Turion Space
Founded: 2020
HQ: Irvine, US
Turion builds autonomous "DROID" satellites for space domain awareness, satellite inspection, and eventually active debris removal. It has raised $79.8 million across four rounds and won a $1.9 million SpaceWERX contract (partly NASA-funded) for a debris-capturing "micro-Droid" concept.
The company is targeting 45 satellites per year production by 2027. Its USP is full vertical integration - Turion builds its own satellites, flight software, and imagery pipeline, and is optimising for "delta-V per dollar" as its core engineering metric. Given the surge in orbital congestion, Turion’s SDA satellites and software are a high-growth play.
8. Reflex Aerospace
Founded: 2021
HQ: Berlin / Munich, Germany
Reflex builds payload-centric satellite buses without relying on expensive megafactories, targeting Europe's ISR (intelligence, surveillance, reconnaissance) and defense needs. It raised €50 millon in Series A (Nov 2025) - the largest Series A in European New Space history.
This comes as Germany commits ~€35 billion to space-related defense through 2030 under the EU's forthcoming European Space Shield Initiative. Reflex's first satellite (SIGI) was built in just 13 months. By offering rapid-turnaround, vertically-integrated smallsat production in Europe, Reflex addresses demand for sovereign satellite supply. Its multi-modal VLEO / LEO platforms and recent injection of capital make it a rising player in the crowded smallsat market.
9. Muon Space
Founded: 2021
HQ: Mountain View, US
Muon Space is a "Mission Foundry" providing full-stack satellite constellations for Earth intelligence - hardware, software, and analytics. It has raised $136 million across six rounds, including a $146 million Series B.
Its flagship program, FireSat, deployed its first three operational wildfire-detection satellites in July 2026, with a 50+ satellite constellation planned. Customers include NRO, Space Force, and SDA. With climate and defense data constellations on the rise, Muon’s end-to-end approach mark it as a strong contender in commercial smallsat manufacturing.
10. Portal Space Systems
Founded: 2021
HQ: Bothell, Washington, USA
Portal is building Supernova, a spacecraft powered by solar-thermal propulsion (concentrated sunlight heating ammonia propellant) - delivering nuclear-thermal-like performance without a reactor. It has raised $70 million+ total.
Supernova targets LEO-to-GEO transfers in hours and LEO-to-cislunar in days, with 6 km/s of delta-V - 50x the range of typical satellite buses. Supernova’s tank-pressurisation and megawatt-class engine (concept) could extend satellite life and reduce orbital injection costs - Portal’s tech promises a step-change in launch logistics.
11. Stellar Alpina
Founded: 2026
HQ: Zurich, Switzerland
The newest company on this list - founded in 2026 by four alumni of Switzerland's student rocketry program (ARIS) - Stellar Alpina develops rotating detonation rocket engines (RDREs) for in-space mobility, a propulsion architecture that is smaller and more efficient than conventional chemical engines. It raised CHF 3.5 million (~€3.8 million) in pre-seed funding, just 82 days after incorporation, having already completed Europe's first known commercial RDRE hotfire campaign.
Stellar Alpina is an extreme example of how fast European deep-tech teams are now moving from concept to tested hardware - a bet on detonation propulsion becoming the next step-change in orbital mobility. As a novel in-space engine, Stellar Alpina stands out in the emerging next-gen propulsion field.
12. PAVE Space
Founded: 2024
HQ: Lausanne, Switzerland
PAVE Space (a spin-off of the student-led Gruyère Space Program) is building the LYOBA heavy-lift kick stage and IBEX mobility platform to move satellites rapidly between orbits - Europe's answer to Impulse Space. It closed a $40 million seed round in March 2026.
The company already has eight reservation agreements with satellite operators. PAVE Space is positioned squarely at the intersection of European sovereignty, defense investment, and orbital logistics demand.
13. Apolink
Founded: 2024
HQ: Palo Alto, US
Apolink is building a hybrid RF-optical satellite relay network to eliminate "dead zones" - the gaps when LEO satellites lose ground-station contact. It raised $4.3 million in an oversubscribed seed round (July 2025, Y Combinator-backed) at a $45 million post-money valuation.
Apolink has already secured $140 million+ in letters of intent from customers like Astro Digital and Hubble Network. As NASA winds down its legacy TDRS relay system, commercial operators need a replacement - Apolink is targeting that gap with a hardware-agnostic, 24/7 connectivity layer.
14. Albedo
Founded: 2020
HQ: Denver, US
Albedo builds satellites for Very Low Earth Orbit (VLEO) that capture 10 cm-resolution optical and 2 m thermal imagery - quality previously only achievable from aircraft or classified military satellites. It has raised ~$97 million total, was valued around $285 million pre-money in an April 2025 Series B raise, up from $150 million in 2023.
Its first satellite, Clarity-1, is on orbit, backed by a $12 million US Air Force contract. Albedo’s key differentiator is combining VLEO orbits (200–300 km) with rugged satellites built to survive atomic oxygen. This yields much sharper imagery and smaller launch vehicles for same coverage. Albedo has contracts via Booz Allen to analyse its Clarity-1 data for NRO and AFRL. Its sensors and low-altitude focus give it a niche in defense / intel and high-value remote sensing.
15. Gravitics
Founded: 2021
HQ: Marysville, Washington, US
Gravitics builds large, modular space station structures - its StarMax module offers nearly half the ISS's usable volume in a single launch. It has raised $80 million ($20 million seed in 2022, plus a $60 million Space Force STRATFI grant in 2025), and signed a $125 million contract with Axiom Space to supply a pressurised module for Axiom's commercial station.
As NASA winds down the ISS by ~2031, Gravitics is positioning itself as the core hardware supplier - not the operator - for the emerging commercial-station ecosystem (Axiom, Starlab, Orbital Reef). By standardising large structures, Gravitics aims to speed up station construction and on-orbit logistics, appealing to both ISS successors and militaries looking for responsive space logistics.
16. ElevationSpace
Founded: 2021
HQ: Sendai, Japan
A Tohoku University spin-off, ElevationSpace is developing Japan's first privately-led reentry satellite ("Aoba") and a broader "space-to-Earth transportation" platform (ELS-R / ELS-RS) for research and manufacturing payload return. Funding has scaled quickly: from $2.7 million seed (2022) to ¥6.4 billion in Series B (June 2026), bringing total funding past $63.5 million.
Partnerships include Axiom Space, Redwire, and Toyota Industries (heat-resistant materials). The company is Japan's clearest bet on the "downmass" segment of the orbital economy - recovery and return - as ISS retirement approaches.
17. Reditus Space
Founded: 2024
HQ: Atlanta, US
Founded by two Georgia Tech aerospace PhDs, Reditus builds ENOS, a reusable reentry vehicle offering fast, affordable microgravity access for pharma and materials research - filling the gap left by the retiring ISS. It raised $7.1 million–$7.6 million in seed funding and completed its first flight-ready ENOS vehicle just 15 months after founding, with a debut mission targeted for 2026.
The company offers a genuinely different engineering approach - a single integrated reentry vehicle (80%+ of the craft returns) rather than a large satellite with a small attached capsule - aimed at rapid, repeatable, low-cost reflights.
18. Starcloud
Founded: 2024
HQ: Redmond, Washington, US
Starcloud is building orbital AI data centers - satellites carrying Nvidia GPUs, powered continuously by solar energy and radiatively cooled by space. It became the fastest Y Combinator company ever to reach unicorn status, raising a $170 million Series A at a $1.1 billion valuation (April 2026), for $200 million total raised.
Starcloud-1 (with an Nvidia H100) already trained an AI model in orbit; Starcloud-2 (Nvidia Blackwell) is next, working with AWS, Google Cloud, and Crusoe. It has filed with the FCC for a constellation of up to 88,000 satellites. As terrestrial data centers hit power and land constraints, Starcloud is the one most aggressive bet yet that AI compute moves to orbit.
19. Orbital Operations
Founded: 2024
HQ: Long Beach, US
Founded by ex-Relativity Space engineers, Orbital Operations is building Astraeus, a high-thrust, reusable, cryogenic (liquid hydrogen / oxygen) space vehicle aimed at satellite defense and rapid orbital maneuvering for the US Space Force. It raised an $8.8 million seed round (August 2025) after emerging from Y Combinator.
The company’s key USP is that it is solving propellant boil-off - the technical barrier that has historically prevented high-performance cryogenic propulsion from operating for long durations in orbit - which could unlock persistent, responsive space-defense capability.
20. Kreios Space
Founded: 2021
HQ: Vigo, Spain
Kreios is developing Air-Breathing Electric Propulsion (ABEP) - thrusters that ionise the thin atmosphere itself as propellant, enabling satellites to operate sustainably at 150–400km altitude (VLEO) without carrying fuel. It raised €8 million in seed funding (Sept 2025), on top of a €2.3 million pre-seed, for €10 million+ total.
In August 2026 it contracted Kongsberg NanoAvionics to build the world's first commercial ABEP flight demonstration, targeting 2027–2028. VLEO promises 3x sharper imagery and is expected to see increasing interest coming from defense and security end users. ABEP is what can make the difference in VLEO.
21. Viridian Space
Founded: 2021
HQ: Culver City / El Segundo, US
A rival ABEP developer to Kreios, Viridian is building an "Air-Scooping Electric Thruster" for VLEO satellite operation and eventual in-orbit refueling / servicing. It has raised a modest ~$2 million to date via pre-seed and grant funding.
It has received SBIR contracts from the US Air Force and National Science Foundation (including a $1.7 million Phase II DoD SBIR) and a five-year CRADA with the Air Force at Kirtland AFB. It is an earlier-stage, US-based counterpart to the VLEO propulsion race, backed directly by government R&D dollars rather than large VC rounds - a bet worth watching as the technology matures toward flight.
22. NewOrbit
Founded: 2021 (as a company; VLEO propulsion R&D since 2021)
HQ: Reading, UK
NewOrbit aims to be the first company to fly a commercial payload in VLEO, using its own propulsion system (AURA) and specialised coatings to survive atmospheric drag, atomic oxygen corrosion, and aerodynamic torque simultaneously. It raised an oversubscribed $18.5 million Series A (June 2026).
First commercial satellite (NEO-1) targeted for 2028, with a dedicated "NEO Production Complex" opening in the UK's Thames Valley in 2027. With technical leadership and clear funding, NewOrbit is set to capitalise on emerging markets (ultra-fast global connectivity, EO) that come with running constellations well below traditional orbits.
23. Sophia Space
Founded: 2023
HQ: Pasadena, California, US
Sophia Space builds "TILE" - thin, solar-powered, passively-cooled computing modules designed to become the building block of full orbital AI data centers. It’s IP traces back to a $100 million Caltech / JPL solar-power-beaming research program. The company raised a $10 million seed round (Feb 2026), bringing total funding to $13.5 million, and holds a new US patent (with Caltech) for its space-based data-center architecture.
Alongside Starcloud, it represents the leading edge of "orbital compute" - Sophia's angle is thermal efficiency (92% of generated power going to processing) rather than raw scale.
24. Vast Space
Founded: 2021
HQ: Long Beach, US
Vast is building Haven-1, intended to be the world's first commercial space station (launch targeted early 2027), followed by the modular Haven-2 as a potential ISS successor under NASA's Commercial LEO Destinations program. Founded and largely self-funded (over $1 billion) by cryptocurrency entrepreneur Jed McCaleb, Vast just raised its first major outside round - $500 million at roughly an $8 billion valuation (March 2026).
It has already flown and deorbited a pathfinder spacecraft (Haven Demo) and won a NASA private-astronaut-mission contract. Vast is among the first commercial space-station company to have designed, built, and flown its own spacecraft - a credibility signal in a category (Axiom, Orbital Reef, Starlab) where hardware has mostly existed on paper.
25. Spaceflux
Founded: 2022
HQ: London, UK
Spaceflux operates a global network of ground-based optical telescopes - combining visible and short-wave infrared (SWIR) imaging to enable daylight tracking - feeding its AI analytics platform, Cortex, for space domain awareness (SDA). It raised £5.4 million in seed funding (July 2025), then extended the round by £3.5 million in early 2026, bringing total funding to ~£9M.
In November 2025, Spaceflux won all three major UK government SST (Space Surveillance and Tracking) contracts under the National Space Operations Centre framework - cementing its role as the UK's incumbent sovereign SDA provider for both the UK Space Agency and Ministry of Defence. In June 2026, it signed an MoU with Mitsubishi Electric Corporation to explore bringing its SDA capabilities to the Japanese market.
26. Aetherflux
Founded: 2024
HQ: San Carlos, California, US
Aetherflux is reviving the decades-old idea of space-based solar power (SBSP) with a modern twist - rather than one giant geostationary array (the classic 1970s NASA concept), it's building a constellation of small LEO satellites, each collecting solar energy and beaming it to Earth via infrared lasers rather than microwaves. It has raised $60 million total - $10 million seed plus a $50 million Series A (April 2025).
The company has also received US DoD funding through the Operational Energy Capability Improvement Fund, targeting battlefield power delivery as its first commercial use case (replacing vulnerable diesel-generator convoys). Its first demonstration satellite - built on an Apex Space Aries bus - is slated to launch on a SpaceX rideshare in 2026, aiming to be the longest-distance wireless power transmission ever attempted. The company also announced its "Galactic Brain" orbital data-center concept targeting first commercial node by Q1 2027.
27. Inversion Space
Founded: 2021
HQ: Los Angeles / Torrance, US
Inversion is building autonomous reentry vehicles to deliver cargo anywhere on Earth in under an hour by pre-positioning it in orbit - a "space-based logistics" bet, particularly for defense. The company has raised $54.1 million total, including a $44 million Series A (Nov 2024) plus a $71 million SpaceWERX / AFRL Space Force contract.
It’s subscale demonstrator, Ray, flew in January 2025 (validated propulsion, avionics, and separation systems, though its controlled reentry failed due to a short circuit); the company then unveiled its flagship vehicle, Arc - a 500lb-payload, Mach 20+, fully reusable reentry vehicle - in October 2025, with a first flight targeted in 2026. Arc has also been selected for the Kratos-led MACH-TB 2.0 hypersonic testing program. The company is tackling "the last 62 miles" of logistics - getting cargo the final leg from orbit to a precise point on the ground, particularly valuable for denied or infrastructure-limited environments the military cares about.
28. OrbitAID Aerospace
Founded: 2021
HQ: Chennai, Tamil Nadu, India
OrbitAID is building a network of "fuel stations in space" - tanker satellites that dock with and refuel client satellites via its patented SIDRP (Standard Interface Docking and Refueling Port) - India's homegrown answer to Orbit Fab. It's raised ~$2.04 million total across a pre-seed and seed round.
The company opened a $2 million R&D facility in Bengaluru in September 2025 and works closely with ISRO, IN-SPACe, and TIDCO. OrbitAID is in talks with ISRO and SpaceX for a twin-satellite ("chaser" and "target") docking and refueling demonstration, and in March 2026 signed a supply deal with Polish propulsion firm Liftero for two booster propulsion systems.
29. Lux Aeterna
Founded: 2024
HQ: Denver, Colorado, US
Lux Aeterna is building a fully reusable satellite platform - spacecraft with a built-in heat shield and parachute that survive atmospheric reentry, land, and get refurbished for another flight, rather than burning up after one mission. The company emerged from stealth in June 2025 with a $4 million pre-seed round, then closed a $10 million seed round in March 2026, bringing total funding to $14 million.
Its flagship demonstrator, Delphi, is a 200 kg spacecraft confirmed for a SpaceX rideshare launch in Q1 2027, designed to host a payload, run on-orbit tests, reenter, land, and refly. The company has already secured a Space Act Agreement with NASA Ames and multiple CRADAs, and formed a Defense Advisory Board to pursue US defense applications like downmass, materials return, and payload recovery / upgrade.
30. Rendezvous Robotics
Founded: 2024
HQ: Golden, Colorado, US
Rendezvous Robotics is commercialising TESSERAE - flat-packed, dinner-plate-sized modular tiles that autonomously dock, self-correct, and reconfigure using electromagnetic forces to assemble large structures directly in orbit, rather than relying on a single rocket fairing to define a spacecraft's maximum size. The technology was invented at MIT by co-founder Dr. Ariel Ekblaw (also founder of the Aurelia Institute) and has already flown successful orbital demonstrations. The company emerged from stealth in September 2025 with a $3 million pre-seed round, and data indicates total funding has since grown to $ 8.2 million.
The company is targeting both commercial and national security customers, particularly for large antenna apertures, high-power solar arrays, and radiators that need physical scale no single launch vehicle can deliver in one piece.
