VORAGO Technologies

The Austin chip company that hardens ordinary silicon to survive space radiation, extreme heat, and the harshest missions on and off Earth.

HARDSIL® Process Rad-Hard MCUs Arm Cortex-M Fabless

VORAGO Technologies, Inc. - 2801 Via Fortuna, Austin, Texas. A fabless semiconductor maker photographed by its work: chips built for the vacuum of space and the heat of a drill bit a mile underground.

The Story

Building the chips that don't come back

Space does not forgive weak electronics. A single high-energy particle can flip a bit and corrupt a command; a few hundred thousand rads of accumulated radiation can quietly degrade a transistor until a satellite goes dark. For most of the semiconductor industry, that is somebody else's problem. For VORAGO Technologies, it is the whole business.

Founded in 2004 in Austin, Texas - originally under the name Silicon Space Technology - VORAGO is a fabless semiconductor company that designs radiation-hardened and extreme-temperature microcontrollers and microprocessors. Its customers are the people who build things that cannot be repaired once deployed: satellites, spacecraft, launch vehicles, defense systems, and industrial tools that operate at temperatures where standard chips simply stop working.

The company's central idea is deceptively practical. Rather than designing exotic, ground-up radiation-proof chips, VORAGO created a patented process - HARDSIL® - that hardens commercially designed semiconductors using standard, high-volume manufacturing. Hardness becomes a manufacturing step rather than a moonshot. That single decision shapes everything about how the company competes, prices, and grows.

The Technology

HARDSIL®: radiation hardness as a process step

HARDSIL is described by the company as a node-, foundry- and product-agnostic solution. In plain terms, it adds extra implant steps to an otherwise standard chip-fabrication flow, using the equipment fabs already own. The result is a device that can shrug off radiation and heat that would kill a commercial part - without forcing customers onto a proprietary, low-volume production line.

That approach separates VORAGO from the traditional rad-hard model, where radiation-hardened silicon has historically meant expensive, custom, export-controlled parts produced in tiny quantities. By meeting customers on familiar Arm Cortex-M cores and standard manufacturing, VORAGO lowers both the cost and the learning curve of building for extreme environments.

The company sells the outcome in three flavors. Rad-hard parts target the most punishing missions - deep space, high-radiation orbits, defense systems - with tolerance above 200 krad. Rad-tolerant parts trade some hardness for cost, aimed at low-Earth-orbit satellite constellations that fly cheaper hardware in larger numbers. And high-temperature parts serve terrestrial extremes such as subsurface drilling.

It is an unglamorous kind of engineering, and that is precisely the point. The durability lives inside the manufacturing process, invisible to the end user, right up until the moment a chip keeps working when it was supposed to fail.

The Market

Who buys it, and why it matters

VORAGO's chips end up in places most electronics never survive. A VA10820 microcontroller serves as a system monitor on a next-generation X-ray telescope - an instrument descended from NASA's Swift mission. Another VORAGO part was selected by NOVI for a space computer flown on a SpaceX launch. In 2024, the company demonstrated something more ambitious still: using a rad-hard MCU to reconfigure AMD's space-grade FPGAs in flight, effectively reprogramming hardware logic while it orbits hundreds of kilometers overhead.

The customer base spans aerospace and defense primes, spacecraft and satellite builders, New Space constellation operators, and industrial firms working in subsurface drilling and uncrewed vehicles. These buyers share a defining constraint - their hardware often flies once and can never be swapped - which means they buy trust as much as transistors. A chip that merely works is not enough; it has to keep working, alone, for years, in an environment engineered by physics to destroy it.

Within the broader semiconductor market, VORAGO occupies a specialized high-reliability niche alongside larger suppliers such as BAE Systems, Microchip, Renesas, Frontgrade Gaisler, STMicroelectronics and Texas Instruments' space-grade lines. Its edge is the combination of standard Arm cores, a foundry-agnostic hardening process, and cost-conscious manufacturing - a package aimed squarely at a space industry that is simultaneously going further out and trying to spend less.

Business & Funding

How the company runs

VORAGO operates a fabless model: it designs devices and applies its HARDSIL process at partner foundries, then sells chips, evaluation boards and technology licensing. Products reach engineers directly and through distributors such as Mouser. On the funding side, the company raised a $10M Series D in September 2015 led by New Science Ventures, part of a cumulative venture total reported in the low tens of millions.

Growth has been recognized externally - VORAGO has appeared on the Inc. 5000 list of fastest-growing private companies multiple times (citing roughly 145% three-year revenue growth) and on Deloitte's Technology Fast 500 for three consecutive years. For a deep-tech semiconductor company, that steady compounding is itself a statement: this is a market you win slowly, by going deep.
