Space Startups to Watch in 2026: Our Top 15 Picks

The commercial space industry has never been more dynamic. A new generation of startups is tackling everything from reusable rockets to in-orbit servicing, from satellite cybersecurity to space-based solar power. These are 15 space startups we think are worth watching in 2026 and beyond.

Our selection criteria: strong technical differentiation, credible founding teams, adequate funding for their current stage, and positioning in markets with genuine near-term demand.

Launch and Transportation

1. Stoke Space

HQ: Kent, Washington | Founded: 2019

Stoke Space is building a fully and rapidly reusable rocket, both first and second stages. While SpaceX has mastered first-stage reuse, no one has cracked second-stage reuse at scale. Stoke's upper stage features a novel actively-cooled metallic heat shield for reentry, eliminating the need for thermal protection tiles. In June 2024, Stoke reported the first successful hot fire of Zenith, its full-flow staged combustion engine. If it delivers on its vision, reuse of the entire vehicle could change the economics of spaceflight.

2. Phantom Space

HQ: Tucson, Arizona | Founded: 2019

Phantom Space is building the "Henry Ford of rockets": standardized, mass-produced small launch vehicles designed for high-volume manufacturing rather than bespoke engineering. Its Daytona rocket targets the small satellite market; Phantom has advertised $6 million for Daytona I and $4 million for the upgraded Daytona II. Phantom is also developing satellite buses and a vertically integrated space logistics platform.

3. Gravitics

HQ: Seattle, Washington | Founded: 2021

Gravitics is developing large-volume space modules: habitats and station segments for commercial space stations. Their modules target the commercial space station market, providing low-cost habitable volume for companies like Vast and Axiom. Gravitics is positioning itself as the "module supplier" rather than a station operator, a smart wedge into the emerging orbital infrastructure market.

Earth Observation and Analytics

4. Albedo

HQ: Denver, Colorado | Founded: 2020

Albedo is building a constellation of very low Earth orbit (VLEO) satellites that fly at just 200-300 km altitude, much lower than typical EO satellites at 500-600 km. This enables 10-centimeter optical resolution from commercially available optics, matching what previously required billion-dollar government satellites. Albedo's first satellite, Clarity-1, launched on March 14, 2025; the company says it proved sustained operations in very low Earth orbit and validated about 98% of the technology needed for 10 cm imagery.

5. Muon Space

HQ: Mountain View, California | Founded: 2021

Muon Space is building a vertically integrated Earth observation platform focused on climate data. Rather than selling raw imagery, Muon delivers turnkey climate intelligence products: greenhouse gas monitoring, wildfire risk assessment, and methane leak detection. Their constellation combines multiple sensor types (microwave radiometry, thermal infrared) for all-weather climate monitoring. The climate data market is enormous and growing, driven by carbon credit verification and ESG compliance requirements.

6. Tomorrow.io

HQ: Boston, Massachusetts | Founded: 2016

Tomorrow.io operates a proprietary weather radar constellation in orbit. Their satellites carry miniaturized radar instruments that can detect precipitation and atmospheric conditions from space, filling gaps in ground-based weather radar coverage. Tomorrow.io combines its proprietary satellite data with third-party data and AI models to deliver hyperlocal weather forecasting for aviation, logistics, energy, and agriculture customers.

In-Orbit Services and Manufacturing

7. Astroscale

HQ: Tokyo, Japan | Founded: 2013

Astroscale is the global leader in orbital debris removal and in-orbit servicing. Their ADRAS-J mission approached a defunct H-IIA rocket upper stage to within 15 meters in 2024, and the company is developing ELSA-M, a multi-client satellite removal vehicle. Astroscale has been listed on the Tokyo Stock Exchange Growth Market since June 5, 2024.

8. Varda Space Industries

HQ: El Segundo, California | Founded: 2020

Varda builds autonomous space factories: spacecraft that launch to orbit, manufacture high-value products in microgravity, and return them to Earth in reentry capsules. Their first mission, W-1, launched in June 2023, grew crystals of the antiviral drug ritonavir in orbit, and landed in Utah on February 21, 2024. Varda is scaling toward regular production, initially focused on pharmaceuticals where microgravity enables superior crystal structures for drug formulations. If space manufacturing economics work at scale, Varda could be building the factories of the future.

9. True Anomaly

HQ: Denver, Colorado | Founded: 2022

True Anomaly is building space domain awareness and proximity operations capabilities for the US Space Force and commercial customers. Their Jackal autonomous spacecraft is designed for close-proximity inspection and characterization of objects in orbit. As space becomes more congested and contested, the ability to understand what other objects in orbit are doing, and to operate safely near them, is becoming a critical national security and commercial capability.

Communications and Connectivity

10. Astranis

HQ: San Francisco, California | Founded: 2015

Astranis builds small geostationary broadband satellites: a novel approach that combines the coverage advantages of GEO (always visible from a fixed point on Earth) with the cost advantages of small satellites. Each MicroGEO satellite provides dedicated broadband capacity for a specific country or region, serving markets too small to justify a traditional large GEO satellite. Astranis launched its first satellite, Arcturus, in 2023 (a solar array problem kept it from serving its Alaska customer), and says it now has five GEO satellites in orbit.

11. Lynk Global

HQ: Falls Church, Virginia | Founded: 2017

Lynk Global connects standard, unmodified cell phones directly to satellites, no special hardware required, as do AST SpaceMobile and SpaceX/T-Mobile. Its technology provides text messaging, emergency alerts, and basic data service to existing phones. Since August 2026 Lynk has been part of Elveo Mobile, after its merger with Omnispace closed.

Infrastructure and Propulsion

12. Impulse Space

HQ: Redondo Beach, California | Founded: 2021

Founded by Tom Mueller, a SpaceX founding member and the architect of its Merlin engines, Impulse Space is building in-space transportation vehicles: orbital transfer vehicles (OTVs) that pick up satellites from the rideshare drop-off orbit and deliver them precisely where they need to go. Their Mira OTV provides the "last mile delivery" service for satellites, and the larger Helios vehicle will serve cislunar transportation needs. As launch becomes commoditized, in-space logistics becomes the next bottleneck, and the next opportunity.

13. Atomos Space

HQ: Denver, Colorado | Founded: 2020

Atomos is developing orbital transfer vehicles using high-efficiency electric propulsion. Their vehicles dock with client satellites after launch and transport them to their operational orbit, extending satellite life by saving on-board propellant, or repositioning assets as mission requirements change. Atomos is also developing technology for satellite refueling and life extension: services that become more valuable as satellite constellations scale.

Sustainability and Cybersecurity

14. Slingshot Aerospace

Founded: 2017

Slingshot Aerospace provides space domain awareness and situational intelligence through its Seradata and Beacon platforms. Their digital twin of the space environment enables satellite operators, insurers, and regulators to understand collision risk, conjunction events, and orbital traffic patterns. With about 15,900 functioning satellites in orbit (ESA, October 2026), the demand for space traffic management intelligence grows exponentially. Slingshot is building the "air traffic control" data layer for space.

15. SpiderOak

HQ: Reston, Virginia | Founded: 2006

SpiderOak provides zero-trust cybersecurity for space systems. Their OrbitSecure platform enables secure data sharing and communication between satellites, ground stations, and mission operations without relying on centralized key management, critical when satellites can be targeted by nation-state cyber actors. As satellite constellations become critical infrastructure for communications, navigation, and defense, cybersecurity for space systems is transitioning from "nice to have" to essential.

Themes Across the List

Several patterns emerge from our top 15:

• Vertical integration is winning: The most compelling startups own their full stack across hardware, software, and analytics. Muon Space builds their own satellites AND delivers analytics. Varda builds factories AND operates the reentry vehicles
• Infrastructure over applications: Many of our picks are building picks-and-shovels infrastructure (OTVs, modules, cybersecurity) rather than end-user applications. In a gold rush, sell the tools
• Regulation as tailwind: Companies like Astroscale and Slingshot benefit from tightening regulations around debris mitigation and space traffic management. Regulatory compliance creates demand that doesn't depend on market cycles
• Climate and defense spending: The two largest growth drivers in space are climate monitoring (ESG, carbon markets, weather) and defense (space domain awareness, secure communications). Startups aligned with these trends have the clearest path to revenue
• Hardware is back: After years of "software is eating the world," space rewards companies that can build and operate hardware. The barriers to entry are higher, but so are the moats
