## What they do

Reliable Robotics builds the Reliable Autonomy System, an FAA-certifiable flight control system that retrofits onto type certified aircraft to automate every phase of flight (taxi, takeoff, enroute, landing) with a remote pilot supervising from the ground.

## Overview

**The SpaceX alumni betting the plane can fly itself, if the FAA signs off**

Reliable Robotics started with a number that is hard to ignore: more than 70 percent of fatal general aviation accidents in the United States could be prevented with better automation. The company's answer is an aircraft that flies itself gate to gate, with a remote pilot supervising from the ground instead of sitting in the seat.

Robert Rose and Juerg Frefel founded it in 2017, both out of SpaceX, where Rose ran flight software for Falcon 9 and Dragon and Frefel led the avionics platforms underneath them. That pedigree is the whole thesis. The hard part of autonomous flight was never the flying. It is convincing the FAA, and Reliable has spent its history building the certification case rather than a flashy demo.

## What They Do

**One certifiable autopilot, retrofit onto aircraft that already exist**

Instead of designing a novel aircraft, Reliable takes a type certified plane and adds the pieces that let it operate without a pilot on board: high-integrity navigation, full-authority flight controls, secure air-to-ground links, air-to-air radar, and fault-tolerant compute. The result is the Reliable Autonomy System, a flight control system that stays engaged through every phase, taxi, takeoff, enroute, and landing.

The design choice that matters is the retrofit. Working with an existing airframe means an existing certification basis, which is why the company got the FAA to accept a certification basis in 2022 and a certification plan in 2023 while most autonomy startups were still arguing about it. The system is aircraft and airspace agnostic, so the same stack is meant to serve civil cargo and military logistics alike.

## Problems

**Fixing the two things that kill pilots and strand small towns**

The safety pitch is specific. Reliable's automation targets the accident categories that dominate the fatality data, controlled flight into terrain and loss of control in flight, by keeping the autopilot engaged and terrain-aware from gate to gate.

The access pitch is the other half. Since 2019 more than 300 rural communities have lost or seen reduced air service, and thousands of general aviation airports sit mostly unused because a crewed regional flight does not pencil out. Take the pilot out of the cost structure and those routes start to make sense again.

### Problems addressed

- Fatal general aviation accidents, over 70% of which the company says are preventable with advanced automation (controlled flight into terrain, loss of control in flight)
- Reduced or eliminated air service to 300+ rural communities since 2019
- Thousands of underused general aviation airports that crewed regional service cannot economically reach
- Pilot shortages and the cost of crewed flight on thin or contested routes

## Who It's For

**Cargo first, the military in parallel, passengers much later**

Reliable is deliberately starting with freight. Its near-term customer is the regional cargo operator flying Part 23 aircraft, where an uncrewed plane is easier to certify and the economics of thin routes are the whole point. Passenger service under Part 25 is on the roadmap, not the pitch deck's front page.

The second buyer is the U.S. government. The company is under contract with the Air Force to automate a Cessna 208B Caravan for contested logistics in the Indo-Pacific, and it is working with NASA and the FAA on the testing that clears the path for everyone else.

### Ideal customer profiles

- **Regional cargo operator** — Thin routes that do not pencil out with a crewed regional flight; Reaching underserved general aviation airports
- **Defense / military logistics** — Resupply in contested, austere environments like the Indo-Pacific; Pilot shortages stretched across vast theaters
- **Aviation safety stakeholder / regulator** — Preventing the accident categories that dominate fatality data; Establishing a certification path and standards for uncrewed operations

## Products

**Everything that turns a normal Caravan into an uncrewed one**

The Reliable Autonomy System is really a bundle of safety-critical subsystems that have to work together and, crucially, be certifiable together. The headline is full-authority flight controls on triple-redundant hardware and software, but the less glamorous pieces, the anti-skid braking that prevents runway excursions and the terrain-aware flight planning, are what make gate-to-gate autonomy real rather than a marketing line.

The two pieces the company talks about most are its detect-and-avoid radar and its remote piloting model, both of which are the frontier of what the FAA has to accept before uncrewed flights go commercial.

## Business Model

**Sell the automation, not the airplane**

Reliable does not build aircraft. It builds and installs an autonomy system onto planes operators already fly, which keeps it out of the capital-heavy business of manufacturing airframes and squarely in the higher-margin business of certifiable software and avionics. Revenue today leans on government and agency contracts, including a multi-year Air Force award and FAA and NASA testing work, which fund the technology while the commercial cargo certification is still in progress. Pricing is not published; these are negotiated enterprise and defense contracts.

## Competition

**Certification is the moat, not the algorithm**

Plenty of companies can make an aircraft fly on its own in a demo. Almost none have gotten a regulator to agree on how to prove it is safe. Reliable's edge is that it picked the certification fight first: an FAA-accepted certification basis and plan, an existing airframe, and a system built from the start against aerospace assurance standards like DO-178C and DO-254.

That is also the risk. The strategy only pays off if the FAA actually issues the certification, and the timeline for that sits partly outside the company's control.

### Their edge

- **Certification-forward** — An FAA-accepted certification basis and plan put Reliable ahead of demo-stage autonomy rivals on the part regulators actually gate on.
- **Retrofit, not new airframe** — Adding autonomy to type certified aircraft reuses an existing certification basis and avoids the capital and risk of building a novel aircraft.
- **Safety-critical from the start** — The system is built against aerospace assurance standards (DO-178C, DO-254, ARP4754A/4761) rather than adapting consumer-grade autonomy.

### Where they're betting

- Securing the first FAA certification for fully automated commercial cargo flight (Part 23)
- Deploying dual-use autonomy for the U.S. Air Force in the Indo-Pacific
- Expanding from cargo toward Part 25 passenger aircraft over the longer term

## Proof

**A decade of firsts, on the record with the FAA**

Reliable prefers milestones to promises, and it has a run of them. It demonstrated fully automated regional cargo operation from departure gate to arrival gate, got the FAA to accept its certification basis in 2022 and its certification plan in 2023, and was awarded military airworthiness in 2024.

More recently it flew the first test of its detect-and-avoid radar in 2025, strung together seven consecutive autolands the same year, and completed FAA-contracted detect-and-avoid flight testing in airport environments in 2026. In March 2026 the FAA selected Reliable and the City of Albuquerque for its Advanced Air Mobility Integration Pilot Program, aimed at the first commercial regional air cargo service by a large uncrewed aircraft in the U.S.

## What People Say

**A talented, mission-driven crew, with SpaceX intensity to match**

The praise is consistent: employees describe an unusually talented and humble team, a clear mission, strong onboarding, and a culture people compare to family. Unlimited PTO and a genuine sense of purpose come up often.

The criticism is just as consistent, and it rhymes with the founders' background. Reviewers cite a SpaceX-like intensity, crunch periods and burnout, and compensation that some feel does not stretch far enough for the Bay Area even with stock options. The mostly-remote setup also leaves some on-site staff feeling isolated.

## Funding

**$160M more, a valuation near $1B, and a Boeing-and-RTX cap table**

In April 2026 Reliable raised $160 million in a Series D led by Nimble Partners, pushing total funding to roughly $300 million and the valuation to nearly $1 billion. The money is earmarked for exactly what the strategy demands: more engineers and more evidence to hand the FAA for a first commercial uncrewed cargo certification.

The more telling detail is who is on the cap table. Alongside Eclipse, Lightspeed, Coatue, and Pathbreaker, the round pulled in strategic investors from across aerospace and defense, including AE Ventures tied to Boeing, RTX Ventures, Presidio Ventures from Sumitomo, and Socium Ventures from Cox Enterprises.

## Team & Culture

**Built by aerospace and self-driving veterans who like hard problems**

The company recruits mission-driven engineers out of aerospace, robotics, and self-driving cars, and it shows in how the work is framed: safety-critical, hands-on, and cradle-to-grave ownership of the hardware and software you ship. Roles repeatedly describe small teams that take products from prototype to production, and a preference for lifelong learners who want to build the company from the ground floor.

The footprint tracks the mission. Engineering and HQ sit in Mountain View, with flight and production work in San Martin, California, a growing operations base in Albuquerque tied to the FAA pilot program, radar work in Seattle, and pilots stationed as far as Guam.

## Compensation

**Base plus stock options across a wide engineering band**

Compensation is base salary plus stock options, employee medical, and a 401(k) contribution, all in USD. Disclosed engineering bands run wide, from roughly $110,000 at the junior end to $300,000 for senior specialist roles, reflecting how much the pay depends on seniority and domain.

Equity is standard across roles, though some employees note the options do not fully close the gap with Bay Area cash comp. Non-engineering and operations roles land in a narrower, lower band.

## Security & Legal

**Registered in Mountain View, and serious about export control**

The legal entity is Reliable Robotics Corporation, operating out of Mountain View, California, with a privacy notice and terms last updated in January 2022. Standard practices apply: Google Analytics for site metrics, the usual cookie and data-collection disclosures, and California and Nevada privacy supplements.

The sharper detail is export control. Because the autonomy system is dual-use defense technology, every job requires the applicant to establish U.S. person status, and access to the technology is gated by U.S. export control law.

## In the News

**From Congressional testimony to a Transportation Secretary's visit**

Reliable spends real energy in Washington, and the coverage reflects it. CEO Robert Rose testified before Congress on U.S. aviation leadership in late 2025, and in June 2026 Transportation Secretary Sean Duffy toured the company's Albuquerque operation.

The substantive news is the flight testing and the money: FAA-contracted detect-and-avoid testing, a NASA contract for airport-area operations, and the $160 million Series D that Bloomberg framed as a push toward the first commercial uncrewed cargo certification.

## Outlook

**One certification stands between the plan and the payoff**

Reliable has done the patient, unglamorous work: an accepted certification basis and plan, military airworthiness, a defense contract, and a cap table stacked with aerospace strategics. The technology milestones keep landing, from seven straight autolands to detect-and-avoid testing in real airport airspace.

What is left is the hardest part it does not fully control. The entire bet resolves when, and if, the FAA issues the first certification for fully automated commercial cargo flight. Get there and the rural-air-service and defense-logistics markets open at once. Miss the timeline and it stays a very well-funded science project.
