Beyond Reach Labs Raises $10M Seed to Mass-Produce 100-Meter Deployable Solar Arrays

Beyond Reach Labs, a startup building hardware that helps satellite operators deploy very large solar arrays, has raised a $10 million seed round to meet what it describes as a massive incoming wave of demand. Interlagos led the round, with participation from TerraForge Capital, Off-Piste Capital, Y Combinator, and Augur VC. Alongside the raise, the company opened a new 16,000-square-foot manufacturing facility in Brooklyn, New York — a statement of intent that this is a production company, not a research project.

The Deal at a Glance

Founded in 2023, Beyond Reach traces its core technology to a NASA grant supporting research into large-scale space structures. The commercial inflection came when the company joined Y Combinator's Winter 2026 cohort and narrowed its near-term focus to solar arrays — the application where demand is most immediate. After demoing the technology at Y Combinator in March, customer interest arrived in force: the company has since signed $342.6 million in letters of intent with future customers and has paid pilot programs underway, according to CEO Mitchell Fogelson.

The syndicate blends deep-tech conviction with accelerator validation: Interlagos in the lead, TerraForge Capital, Off-Piste Capital, Augur VC, and Y Combinator itself doubling down on its cohort company. The capital is aimed squarely at scaling: the company intends to have its system flight-qualified by the end of the year and to ramp the Brooklyn facility toward producing more than ten units a day by the end of 2027.

The Problem: Power Has an Upper Limit

No matter how lofty the industry's ambitions become, spaceflight remains governed by size, weight, and power — SWaP. As organizations design larger, more complex spacecraft, the solar arrays needed to feed them have become unwieldy. According to Beyond Reach, today's array technology faces a structural ceiling: the larger the array, the more susceptible the spacecraft becomes to vibrations as it maneuvers and cycles through extreme temperature swings. The conventional fix — stiffening the array — adds mass, which erodes the economics of the entire mission.

Beyond Reach's answer is a patented solar array deployer that can extend 100 meters yet folds flat into a typical launch fairing. As CTO and cofounder Pele Collins put it, the patented designs all fundamentally solve the same problem: how to make something extremely long that does not behave like a floppy noodle. Solving stiffness without mass is the whole game — and it is what the company believes separates its hardware from the current state of the art.

From Demo Day to $342.6M in LOIs

The company's aggressive flight-qualification timeline — end of this year — is driven by the customer response since its March demo. Letters of intent are non-binding, and the industry has learned to discount them accordingly, but $342.6 million in signed LOIs plus paid pilots is a demand signal few seed-stage hardware companies can show. Paid pilots matter most: customers spending real money to evaluate hardware are customers with genuine integration intent.

The Commoditization Thesis

Fogelson's framing of the opportunity is the most strategically interesting part of the story. He argues deployable solar arrays should feel like valves or motors — standard subcomponents nobody builds in-house. Spacecraft designers, in his telling, do not want to engineer power systems; they want an outlet to plug into. That is a bet on the maturation of the space supply chain: as the industry industrializes, vertically integrated one-off engineering gives way to specialized merchant suppliers who win on volume, reliability, and price.

Beyond Power: The Large-Structures Roadmap

Solar arrays are the entry point, not the destination. Fogelson describes the long-term vision as becoming the architect for next-generation large space systems — expanding into deployable radiators, structures, and other products supporting large-scale space infrastructure, potentially including the Moon. The underlying insight is that many things in space get better as they get bigger: more power, more heat rejection, more aperture, more habitable volume. A company that owns the hard problem of making big things packable and stiff has a platform, not a product.

The BlacKnight Take

This round is a snapshot of the space economy's industrial turn. The demand wave Beyond Reach is riding comes from exactly the megaprojects the industry has been promising — space stations, orbital compute, large platforms — all of which are power-starved by today's array technology. The company's positioning is textbook: solve the physics bottleneck (stiffness without mass), productize it as a boring, reliable subcomponent, and scale manufacturing before competitors convert their slideware.

For founders, two lessons stand out. First, the sequencing: NASA-funded research roots, an accelerator to force commercial focus, a demo that generated a nine-figure LOI pipeline, then a seed round priced on demand rather than promise. Second, the location: a Brooklyn factory is a bet that hardware talent, capital, and customers no longer require a coastal aerospace enclave — and that speed of hiring and iteration beats legacy geography. Watch the flight qualification at year end; if the hardware performs, Beyond Reach will have turned the industry's power ceiling into its own growth curve.
