Serve Robotics has agreed to acquire healthcare robotics company Diligent Robotics, marking its first expansion from outdoor sidewalk delivery into indoor environments such as hospitals. The deal brings Diligent’s autonomous hospital robot, Moxi, into Serve’s portfolio and extends its autonomy platform into healthcare settings that demand high reliability, safety, and close human interaction.
Key takeaways
- Moxi is deployed in more than 25 U.S. hospital facilities, with over 1.25 million autonomous deliveries completed to date.
- The acquisition is valued at $29 million in Serve common stock, with a potential earn-out of up to $5.3 million based on performance milestones.
- Each hospital deploying Moxi is expected to generate between $200,000 and $400,000 in annual revenue, higher than last-mile delivery.
- Serve and Moxi will share one autonomy stack, data flywheel, and operating system, enabling learning across both outdoor and indoor environments.
Hospitals present dense, multi-level environments with constant human activity, doorways, elevators, and unpredictable edge cases. Serve says experience from Moxi’s daily operations will feed back into a shared autonomy stack, improving learning, deployment speed, and scalability across its wider fleet. Diligent’s customers include Northwestern Medicine, ChristianaCare, and Rochester General Hospital. Moxi robots use Nvidia Jetson for onboard computing and are trained with Nvidia Isaac simulation tools. Diligent will continue to operate as a subsidiary under the leadership of co-founder Andrea Thomaz. The transaction is expected to close in Q1 2026, subject to regulatory approvals.
