Stellios Raises $5M to Build Microwave Power Systems

The optional diesel generator on Stellios Technologies' Shield product page brings its directed-energy pitch down to earth. A customer considering a microwave defense system has to decide how to power the equipment, where to mount it and how it will operate alongside everything already on site. The purchasing decision reaches well beyond the source producing the microwaves.

Founded and led by Richard Starson, Stellios Technologies announced a $5M pre-seed financing on October 20, 2026. Participants include Sofreh Capital, Wave Function Ventures, Cubit Capital, Mana Ventures, Atoms & Bits, Output Capital and Erik Bruckner, alongside other strategic investors. The company reports entering the financing with $2M in signed customer purchase orders; that figure describes commitments to buy, with delivery and revenue recognition still separate questions.

Stellios intends to use early microwave hardware work to establish capabilities for a broader power-systems business, including compact fusion research. For operators evaluating its immediate offering, the financing matters because it supports the practical work between accepting an order and putting equipment into a customer's hands. Its longer energy ambition will develop alongside that much nearer obligation.

What Stellios is offering microwave-system buyers

Shield's published pilot configurations span 200 kW to 1 MW, with vehicle-mounted or stationary deployment and integrated power supplies. The company targets delivery 9 months after an order. Those figures describe its advertised offering and timetable; buyers should read them as vendor specifications rather than an independently demonstrated operating record.

The configurations make the integration work visible. An installation needs a workable combination of power, physical equipment and its intended operating environment, making the purchase more involved than selecting an output number. Stellios' decision to supply microwave sources and the systems driving them places more of that relationship inside one young manufacturer.

The U.S. Government Accountability Office's May 2023 directed-energy assessment explains the appeal of the category: electromagnetic systems can offer rapid engagement and potentially lower costs per shot, with some technologies able to affect multiple targets. GAO also identifies cooling and range constraints, and warns that broad-beam microwave effects can reach friendly as well as hostile assets. The operating setting belongs inside the equipment evaluation.

For Stellios, this means the customer conversation will have to accommodate both power-system engineering and the environment in which the buyer expects to use it. A nine-month delivery target establishes a commercial clock. What must arrive at the end of it is an integrated configuration the customer can assess, install and put through its own acceptance process.

Austin hiring puts manufacturing inside the funding story

Stellios' current careers page says its hardware is built primarily in Austin, Texas. The site still carries an El Segundo, California footer elsewhere, so the most precise geographic description follows the work: Austin is the stated center of its hardware activity. The funding announcement also carries an Austin dateline.

Its recruitment list covers high-power microwave sources, high-voltage systems, RF and plasma research, superconducting magnets, technical program management and hands-on fabrication. Those openings describe the organization Stellios wants to build, rather than a completed roster. They make an important commercial choice legible: manufacturing and coordination are being developed alongside the physics. The production emphasis connects with DevCuration's coverage of CorePower Magnetics' U.S. manufacturing plans, another view of capital going toward the capacity to build power hardware.

A machine-shop role and a program-management role bring different obligations into the same delivery calendar. One turns a design into a physical assembly; the other helps ensure suppliers, schedules and the assembled system meet. For an early hardware company, the relationship between those tasks can determine how much of an engineering result becomes a repeatable product.

The financing therefore reaches into the ordinary work surrounding extraordinary power levels. Stellios has described plans for domestic research and pilot-manufacturing capacity, with engineering and leadership expansion among the uses of capital. The company's first purchase commitments give that capacity a customer destination while the team is still forming.

Genesis and compact fusion run on different development clocks

Stellios' Genesis engineering platform offers a second view of its development process. The company says it uses the software internally and is making it available to other engineers and researchers. Its listed tools combine AI-assisted CAD, circuit work, research and physics analysis in a local engineering environment.

The product page is explicit about maturity: Genesis is experimental, with no guarantees or service-level commitments, while full finite-element and multiphysics simulation remain in development. That description helps separate the tools available to an early user from the more complete engineering environment Stellios intends to build. An outside subscriber is joining an evolving product.

The company's longer-term plan connects microwave systems with Stellios Core, its compact-fusion program. Its argument is that capabilities in magnets, vacuum systems, power electronics and controls can carry across the programs. That makes early manufacturing experience valuable to the wider strategy, even though a fusion system introduces its own development demands.

This sequencing gives investors several linked activities to evaluate: equipment delivery, engineering software and longer-horizon energy research. Wave Function Ventures' portfolio independently lists Stellios under directed energy and compact fusion, corroborating its connection to the company. The public material reviewed does not establish commercial fusion output or a completed energy product; those remain part of the development agenda.

The first deliveries give the broader plan a working calendar

Stellios has placed contracted microwave deliveries, domestic facilities, team expansion, customer programs, Genesis and early fusion research within its funding plans. The breadth makes allocation consequential: the same organization is building its immediate ability to deliver while exploring technology intended for a much longer future. Neither the purchase-order figure nor the financing amount supplies the missing detail of that allocation.

For a prospective customer, the useful questions now attach to a particular configuration and delivery relationship. What power and installation arrangements belong in the order? What performance will the customer verify before accepting the system? Those are practical purchasing questions raised by the published offering, without requiring a prediction about the eventual fusion program.

Stellios' near-term story will develop around the machines already ordered and the people being recruited to build them. Each delivery can add operating experience to its wider power-systems effort. The customer waiting for a microwave system has a nearer date on the calendar than the energy future described in the company's vision.
