RRE Ventures Has Been Playing the Long Game Since 1994 - and It Shows
The New York firm wrote early checks into Palantir, Datadog and Venmo, then stayed in the boardroom for the parts that actually get hard.
Beyond Reach Labs
Beyond Reach Labs is a New York space-hardware startup building ultra-light deployable solar arrays that pack down to the size of a dining table and unfold to the size of a football field in orbit, delivering roughly 10x more usable power per launch without adding mass or volume. Founded by former NASA researcher Mitchell Fogelson and ex-SpaceX parachute lead Pele Collins, the company grew out of NASA-funded research into kilometer-scale space structures and is targeting a 2027 in-space flight demonstration.
SkyFi
SkyFi is an Austin, Texas-based Earth intelligence company that runs a self-service marketplace for satellite imagery and analytics. Through a single web platform, mobile app and API, customers can search archives, task satellites and buy optical, SAR, hyperspectral and aerial imagery from more than 50 commercial providers - then run built-in AI analytics on it. Founded in 2021 by Luke Fischer and Bill Perkins, SkyFi aims to make geospatial data as easy to order as a rideshare, serving defense, government, finance, energy, agriculture, insurance and infrastructure customers worldwide.
Array Labs
Array Labs designs, builds, and operates radar satellites that fly in coordinated clusters to image the same place on Earth from many angles at once. By distributing the radar across many small, mass-manufacturable satellites instead of one large bespoke spacecraft, the company aims to produce continuously refreshed, high-resolution 3D maps of the planet - a form of space-based radar it likens to what SpaceX did for launch. Founded in 2021 and based in Redwood City, California, Array Labs raised a $20M Series A in January 2026 to scale radar manufacturing and prepare to launch the world's first formation-flying radar satellite cluster.
Flow Engineering
Flow Engineering builds an AI-native requirements and systems-engineering platform that lets complex hardware teams design, build, test, and iterate at software speed. At its core is a connected 'systems graph' that keeps requirements, CAD, code, simulations, tests, and certification artifacts in one live system of record - with AI agents running impact analysis and keeping everything aligned. Founded by mechanical engineer Pari Singh, Flow is used by companies like Rivian, Joby Aviation, Astranis, Stoke Space, and Figure, and raised a $23M Series A led by Sequoia in October 2025.
CREAN®
CREAN, Inc. is an Austin, Texas-based aerospace engineering and Smart Factory company that supplies hands-on engineering services and manufacturing-optimization programs to space, defense, and commercial clients. Founded in 2002 by James and Jennifer Crean, the firm fields teams of aerospace subject-matter experts who help customers move systems from concept through full-scale production while modernizing factory operations. CREAN is also developing CelestNet, a proposed lunar communications and navigation network, following its 2023 acquisition of Aquarian Space.
Oligo Space
Oligo Space is a Hawthorne, California startup building an AI-first stack for designing and manufacturing payload-centered spacecraft. Its software engine, Zenith, turns raw mission requirements into flight-ready ESPA-class spacecraft using generative design, constraint solving and physics-based optimization - compressing work that once took teams of specialists months into a process that runs in minutes and manufactures in under eight months. Founded in 2024 by MIT AeroAstro graduate and former NASA JPL engineer Jacob Rodriguez, the company plans to fly its first spacecraft, Chimera-1, aboard SpaceX's Transporter-15 mission in 2026.
Starpath
Starpath is a Hawthorne, California space company building robotic factories that mine water ice from the Moon and refine it into rocket propellant. Founded in 2022 by former SpaceX engineers, the company designs fleets of autonomous mining rovers, on-site refineries, and liquid oxygen (LOX) storage systems to produce fuel where rockets actually need it - off Earth. The bet is simple and audacious: if you can make oxidizer on the Moon, you can make deep space travel affordable and turn humanity into a multi-planet species. Starpath raised a $12M seed round in 2024 co-led by 8VC and Fusion Fund.
True Anomaly
True Anomaly is a Colorado-based space defense company building the hardware and software to operate, defend, and win in contested orbit. Its flagship Jackal autonomous orbital vehicle - a highly maneuverable, refrigerator-sized spacecraft - is paired with Mosaic, a full-stack mission autonomy and command-and-control platform. Founded in 2022 by Air Force and Space Force veterans, the company sells primarily to the U.S. Space Force and Department of the Air Force, has raised more than $1 billion across four rounds, and is valued at $2.2 billion after its April 2026 Series D.
Antares
Antares is a nuclear fission energy company building factory-produced, transportable microreactors that deliver strategic power for mission-critical systems across land, sea, and space. Founded in 2023 and headquartered in Torrance, California, its R1 reactor uses TRISO fuel, sodium heat pipes, and a nitrogen Brayton cycle to produce 100kWe-1MWe for six-plus years. In June 2026 its Mark-0 reactor became the first privately developed advanced reactor to achieve criticality under the U.S. Department of Energy's Reactor Pilot Program.
Astranis Space Technologies
Astranis builds small, software-defined geostationary communications satellites - about the size of a washing machine - that deliver dedicated broadband to underserved regions and governments. Founded in 2015 in San Francisco, the company designs, manufactures and operates its MicroGEO platform entirely in-house at Historic Pier 70.
Loft Orbital
Loft Orbital is a San Francisco-based space infrastructure company that flies customer payloads on standardized satellites - selling space access the way AWS sells compute. Customers skip the spacecraft-building part and ship hardware, software, or on-demand data tasks to orbit on Loft's YAM satellites.
Muon Space
Muon Space is a Mountain View-based end-to-end space systems company that designs, builds, and operates mission-optimized satellite constellations for climate, defense, and Earth intelligence customers. Its Halo platform pairs the modular MuSat spacecraft bus with MuOS middleware and the MuSim digital twin, anchoring high-profile programs like Google's FireSat wildfire constellation and a $44.6M U.S. Space Force environmental monitoring agreement.
Astro Digital
Astro Digital designs, builds and operates small-satellite systems delivered as turn-key 'Mission-as-a-Service' offerings - covering spacecraft bus, payload integration, launch, ground network and mission operations - for earth observation, communications, science and in-orbit demonstration customers from LEO to GEO.
Wardstone
Wardstone is a Y Combinator F25 defense startup building a global constellation of satellites equipped with space-based interceptors to kinetically destroy hypersonic and ballistic missiles. Founded by brothers Sebastian and Tobias Fischer, the company is pursuing America's Golden Dome initiative - a layered missile defense system that can engage threats in space before they reach US soil. With a $5M seed round and three successful automated intercept demonstrations during YC, Wardstone is positioning itself as a next-generation missile defense contractor targeting a $40B/year market.
Zephyr Fusion
Zephyr Fusion is building the first in-orbit fusion power source - a compact, megawatt-class reactor designed to run in the vacuum of space. Founded by two physicists who met in grad school operating a spherical tokamak, the San Diego-based startup uses a levitated dipole magnetic confinement approach with high-temperature superconductors. Their bet: space makes fusion easier, not harder. With launch costs down 10x and mass-produced HTS tapes providing 10x more field per kilogram, Zephyr Fusion aims to power the industrial revolution that humanity is about to have off-planet.
