Welcoming Diligent Robotics: Bringing Our Autonomy Platform Into Hospitals

Welcoming Diligent Robotics: Bringing Our Autonomy Platform Into Hospitals

Deploying robots in human spaces demands a particular kind of engineering: reliability, safety, and an unobtrusive presence.

Serve Robotics has entered into an agreement to acquire Diligent Robotics, the maker of Moxi, an autonomous hospital delivery robot.

Diligent is a meaningful addition to Serve. It broadens our market opportunity beyond last mile delivery into indoor and healthcare settings, and it brings one of the largest commercial deployments of mobile manipulation robots working alongside people. Moxi is deployed in over 25 hospital facilities across the U.S. and has completed more than 1.25 million autonomous deliveries.

“This acquisition accelerates Serve’s evolution from a robotic delivery company into a full stack autonomy platform,” said Dr. Ali Kashani, CEO of Serve Robotics. “We’ve proven we can deploy robots safely and reliably at scale in complex urban environments. By extending our platform beyond sidewalks and into hospitals, we’re expanding where our Physical AI can operate, learn, and create value. Over time, Serve and Moxi will share one autonomy stack, one data flywheel, and one operating system for robots that work alongside people across city sidewalks and critical institutions. This is how autonomy becomes infrastructure.”

Both Serve and Diligent have built and commercialized autonomous systems that run in complex, dynamic environments and fit into everyday workflows. In hospitals, that means robots that can navigate among people and adapt to constant edge cases without getting in the way.

The transaction marks Serve’s first expansion of its autonomy platform into indoor environments, with hospitals representing one of the most high-impact settings for robotics.

Indoor environments such as hospitals add a powerful new dimension to Serve’s Physical AI flywheel. Dense, human centric, multi level spaces introduce challenges that push autonomy systems to improve. Operating in these environments contributes to a shared autonomy stack that informs how the platform evolves across applications.

Diligent is one of the few robotics companies that has proven what it takes to operate at scale in live hospital environments.

“Diligent was founded to help healthcare teams do more with their limited resources,” said Andrea Thomaz, CEO of Diligent Robotics. “By joining Serve, we can build on the autonomy and AI we’ve deployed across hospital fleets and scale it faster, enabling more intelligent, capable robots in care environments. Together, we’re unlocking the next phase of practical, real world robotics and advancing a people plus robots model that prioritizes human impact.”

Moxi supports hospital teams by handling routine deliveries such as supplies, lab samples, and medications, allowing clinicians to spend more time with patients. Diligent reports meaningful time savings for clinical staff across its deployments.

Hospitals are busy, multi level, human spaces with zero tolerance for unreliable systems. That is exactly why they matter.

Much of the conversation around physical AI focuses on what might be possible someday. We focus on what is already working: robots operating in the real world, alongside people, in environments that demand reliability every day.

That is what Serve has built on city sidewalks. It is also what Diligent has built inside hospitals.

Bringing these two efforts together expands where our autonomy platform can operate. Indoor hospital environments introduce challenges that differ from the sidewalk, from navigating tight corridors to coordinating movement in shared spaces, all while fitting seamlessly into existing routines.

These demands matter because they shape how autonomy systems evolve over time.

Together, this combination is intended to support continued Moxi deployments in hospitals, extend Serve’s autonomy platform into indoor environments, and strengthen shared learning across real world applications. Just as importantly, it brings a common operational discipline to two fleets that are already working alongside people at scale.

Healthcare deployments also represent a high value commercial use case for autonomy. As outlined in the press release, each hospital facility deploying Moxi robots is expected to generate between $200,000 and $400,000 in annual revenue, reinforcing the role of indoor robotics in supporting Serve’s long term growth.

This is not about changing what either team has built. It is about extending a platform that has already proven it can earn trust in the real world.

Diligent will continue operating as a subsidiary of Serve under the leadership of Andrea Thomaz.

There are no product changes to announce today. The focus is continuity for Diligent’s hospital partners and employees, while we bring teams together carefully and do the integration work the right way.

Serve and Diligent are aligned on something that matters: robots need to work alongside people, not around them.

Serve was built for real cities and everyday life. Diligent was built to support healthcare teams in the flow of hospital work. In both cases, trust is earned through consistent behavior, safety, and respect for the environments we operate in.

This acquisition reflects our belief that the difference between value and hype in AI comes down to real world application.

We believe autonomous robots will become normal infrastructure in more places than people expect, not because of marketing, but because they solve real problems when they are deployed safely, reliably, and at scale.
