Humble Robotics has raised $51 million in Series A funding to scale its cabless autonomous electric truck, the Humble Hauler. Obvious Ventures led the round, with existing investors Eclipse and Energy Impact Partners also taking part.
The funding takes the San Francisco startup’s total raised to $75 million less than a year after it was founded. Humble emerged from stealth in April 2026 with a $24 million seed round led by Eclipse.
A truck designed as one system, not retrofitted
Most self-driving truck efforts start with an existing truck and add autonomy to it. Humble takes the opposite route. It designs the vehicle and its driving intelligence together as a single system, with no cab and no space set aside for a human driver.
The Hauler is a fully autonomous electric Class 8 vehicle that runs on vision-first artificial intelligence and a modular platform. It moves 40-foot international containers and 53-foot US containers, and its all-electric eAxle powertrain gives it a range of 200 miles at a top speed of 55 mph.
“We’ve spent years proving that a truck can drive itself. The harder question is how to make autonomy something a freight operator can depend on every day.”
Eyal Cohen, founder and CEO of Humble Robotics
Cohen previously worked on Apple’s self-driving car project and Uber’s autonomous driving effort, and later at the self-driving truck startup Waabi. His team includes engineers from Tesla, Waymo and Cruise.
Short regional runs come first
Humble is starting with regional freight routes under 250 miles. These short runs make up 87 percent of US truck tonnage, and they connect the ports, rail terminals, warehouses and distribution centres that keep goods moving.
The Hauler is built for dock-to-dock trips between those facilities, including port drayage, plant-to-warehouse shuttles and container moves inside rail yards. Each of those runs is short and repeatable, which makes it a more controlled place to run a driverless truck than the open highway.
What the new funding pays for
The new capital will advance customer pilots, testing and validation, and early manufacturing. It will also fund a broader family of vehicles built on the same modular platform for different regional freight needs.
Customer pilots using conventional trucks are expected to start in the first quarter of 2027. Those trucks will collect data from selected freight routes while Humble tests its systems in simulation. Commercial operations are expected to begin in the third quarter of 2027, subject to further regulatory approvals.
“Humble isn’t letting outdated assumptions slow the modernization of freight hauling. Solving this will strengthen American supply chains and deliver more dependable, efficient movement between critical infrastructure and facilities across the country.”

The Hauler is not yet moving freight for paying customers. Its prototype runs with a temporary cab and a safety driver under a California test permit. The next year will show whether a truck designed without a driver can clear that gap faster than the retrofitted trucks ahead of it.
