Reliable Robotics lands $115M, crosses $1B mark as FAA review continues

Reliable Robotics has raised $115 million in new funding, bringing its valuation past $1 billion as it advances its automated flight technology through the FAA’s certification process. The California-based startup, led by former SpaceX engineers, is working to automate the Cessna 208B Grand Caravan, a widely used cargo aircraft. While the capital provides additional resources, the company remains focused on securing regulatory approval before moving to fully pilotless operations.

The funding, disclosed on October 20, increases the company’s Series D round to $275 million, up from the $160 million previously announced. The latest round consists of equity and a term loan, with plans to allocate the funds toward expanding production, adding aircraft, and hiring engineers while continuing certification efforts.

Reliable’s near-term objective is to automate key phases of flight under remote oversight, rather than pursuing immediate full autonomy. The FAA’s certification process evaluates multiple factors, including hardware, software, operational procedures, and safety protocols. While the company has conducted flight tests and participates in an FAA program allowing limited operations before full approval, these steps do not guarantee broader regulatory clearance.

CEO Robert Rose has indicated that initial FAA approval for continuous autopilot use could take 18 to 24 months, with remote operation without an onboard pilot still several years away. For now, a pilot will remain in the cockpit during testing. The Grand Caravan’s role in freight operations—particularly on repetitive routes and at smaller airports—makes it a practical candidate for automation, allowing Reliable to demonstrate improvements in pilot workload and operational consistency before pursuing more advanced models.

Beyond technical capability, the business case depends on factors like maintenance predictability, accountability for remotely supervised flights, and robust procedures for handling weather, diversions, and equipment failures. Insurers, customers, and regulators will all require evidence of safety and reliability before accepting the technology for routine use.

The company’s approach differs from other automated flight initiatives, but the broader challenge remains the same: certification is a lengthy process, not a single event. Investors appear optimistic about the long-term potential, but the next significant development will likely be an FAA approval with specific operational constraints. Until then, Reliable is advancing toward autonomous aviation rather than achieving it.

When StartupReader last reported on Reliable on October 20, the focus was on its Series D extension and valuation milestone. The company’s progress since then highlights the gap between investor confidence and regulatory timelines. For aerospace startups, the lesson is clear: funding accelerates development, but certification moves at its own pace. The next phase will depend on demonstrated safety, not just financial backing.
