Can Serve reach sustained profitability as it shifts from fleet expansion to per-robot productivity?

As of its Q1 2026 results, Serve reported a GAAP net loss of about $49 million for the quarter despite 3x sequential revenue growth, and management has said its focus is shifting from growing its roughly 2,000-robot fleet to increasing revenue per robot and recurring software revenue; whether this transition closes the gap to profitability on its reaffirmed 2026 revenue guidance of about $26 million remains to be seen.

How well will Serve integrate Diligent Robotics' hospital logistics business, and can it replicate that success in other new verticals?

CEO Ali Kashani has said the Diligent acquisition was an opportunistic fit rather than the start of a broader acquisition strategy, and that Diligent would continue operating relatively independently within Serve; Diligent itself reported a $22.7 million net loss on $9 million of 2025 revenue and a stockholders' deficit prior to the acquisition, according to Serve's SEC filings.

Serve Robotics

Serve Robotics operates autonomous sidewalk delivery robots for Uber Eats, and expanded into hospital logistics via its 2026 Diligent Robotics acquisition.

Last updated: July 15, 2026

Summary

Serve Robotics designs and operates autonomous sidewalk delivery robots, deployed at commercial scale for Uber Eats and other partners across dozens of U.S. cities. Spun out of Uber’s 2020 acquisition of Postmates, the company went public on Nasdaq in 2024 under the ticker SERV, and in January 2026 acquired hospital-logistics robot maker Diligent Robotics, extending its “physical AI” platform from outdoor sidewalks into indoor healthcare settings.

Company Story

Serve’s roots trace to 2017, when Postmates acquired Ali Kashani’s startup Lox Inc. and put him in charge of Postmates X, an internal division exploring autonomous sidewalk delivery. The team built and piloted Serve-branded delivery robots in Los Angeles, and by the end of 2020 — amid COVID-19 restaurant shutdowns — had completed more than 10,000 contactless deliveries for Postmates. Uber acquired Postmates for $2.65 billion in 2020, and in January 2021 agreed to spin out the Postmates X team as an independent company, Serve Robotics, contributing its intellectual property and a capital investment in exchange for an equity stake. Serve raised a seed round led by venture firm Neo, with Uber, Long Journey Ventures, and other investors participating (SEC filing; TechCrunch).

Over the next several years, Serve built out commercial partnerships and strategic investment from Uber, NVIDIA, Delivery Hero’s DX Ventures, and 7-Eleven’s 7-Ventures, and in June 2022 signed a commercial-scale agreement with Uber Eats to deploy up to 2,000 robots across the U.S. In August 2023, the company went public via a reverse merger, and in April 2024 uplisted to the Nasdaq under the ticker SERV, with Uber and NVIDIA holding significant minority equity stakes at the time. NVIDIA subsequently exited its position in late 2024, while Uber has continued to expand its use of Serve’s robots, including placing over 1,000 additional robots on the road through Uber Eats in 2025 (TechCrunch; The Motley Fool).

In January 2026, Serve announced its acquisition of Diligent Robotics, an Austin-based maker of Moxi, a mobile-manipulation robot deployed in more than 25 U.S. hospitals to shuttle medications, lab specimens, and supplies for clinical staff. The roughly $29 million all-stock-and-cash deal closed later that month, marking Serve’s first expansion beyond sidewalk delivery and into indoor, human-centric environments. CEO Ali Kashani described the move as an opportunistic fit with Serve’s underlying thesis around robots that navigate safely alongside people, rather than a broader pivot into acquisitions (TechCrunch). By its first-quarter 2026 results, Serve reported an operating footprint across 44 cities in 14 states, roughly 2,000 combined indoor and outdoor robots deployed, and a combined fleet approaching 2 million cumulative deliveries (Serve Robotics investor relations).

Founders

Ali Kashani co-founded Serve Robotics and serves as CEO. Born in Tehran, he moved to Vancouver, Canada, at 19 to study computer engineering at the University of British Columbia, later earning a Ph.D. in robotics and computer vision there. He co-founded and served as CTO of Neurio Technology, a smart-home energy-monitoring company acquired by Generac Power Systems, before founding Lox Inc., which Postmates acquired in 2017, setting him on the path to building what became Serve. He holds 15 granted or pending patents (Serve Robotics investor relations; Van Tech Journal).

Other co-founders include Dmitry Demeshchuk, the first engineer to join the Serve team at Postmates, who serves as Co-Founder and Head of Software, and MJ Chun, who previously led product at robotics toy company Anki and serves as Co-Founder and VP of Product & Design at Serve (TechCrunch; The Org).

Products

Serve’s core product is a low-emissions, sidewalk-scale autonomous delivery robot, manufactured by Tier 1 automotive supplier Magna International and assembled in Detroit, which the company says has reached SAE Level 4 autonomy — among the first sidewalk-delivery robots to do so. The robots pick up food and goods from restaurants and retail partners and navigate sidewalks to complete last-mile deliveries, primarily for Uber Eats, with additional partners including 7-Eleven and a Dallas trial combining sidewalk robots with Wing’s delivery drones (Serve Robotics; TechCrunch).

Following its January 2026 acquisition of Diligent Robotics, Serve’s platform also includes Moxi, an indoor mobile-manipulation robot that assists hospital staff with non-patient-facing logistics such as transporting medications, lab specimens, personal protective equipment, and supplies. Moxi is powered by the NVIDIA Jetson platform and trained using NVIDIA’s Isaac Sim and Isaac Lab simulation tools, and had completed more than 1.25 million autonomous deliveries across more than 25 hospital systems — including Northwestern Medicine, ChristianaCare, and Rochester General Hospital — at the time of the acquisition (Serve Robotics investor relations).

Funding

Serve has raised well over $300 million since spinning out of Uber in 2021, combining venture rounds, strategic corporate investment, and public-market offerings. Early funding included a seed round led by Neo (2021) with Uber, Long Journey Ventures, and Western Technology Investment participating; a $13 million seed extension (2021) bringing in Delivery Hero’s DX Ventures and 7-Eleven’s 7-Ventures; and a $10 million strategic investment from NVIDIA (2022), its first in the sidewalk-delivery space. Serve went public via reverse merger with a $30 million financing in August 2023, then uplisted to the Nasdaq with an approximately $40 million offering in April 2024. Since then, it has raised additional capital through public-market offerings, including an $80 million direct offering in January 2025, and used roughly $29 million in stock and $19 million in cash to acquire Diligent Robotics in January 2026 (PR Newswire; TechCrunch). NVIDIA exited its equity position in Serve in late 2024; Uber has retained a minority stake, reported at roughly 12% as of late 2025.

Partnerships

Uber Eats is Serve’s largest commercial partner, with a contract to deploy up to 2,000 robots and continued year-over-year expansion of its order volume through Serve’s fleet. Other commercial relationships include 7-Eleven (an early strategic investor and delivery partner) and a pilot with Alphabet’s Wing combining sidewalk robots and delivery drones in Dallas. Following the Diligent Robotics acquisition, Serve’s healthcare-side partners include hospital systems such as Northwestern Medicine, ChristianaCare, and Rochester General Hospital, and Diligent’s Moxi robots run on NVIDIA’s Jetson, Isaac Sim, and Isaac Lab platforms.

Market Context

In sidewalk delivery, Serve competes most directly with Starship Technologies and, to a lesser extent, delivery-drone operators like Wing and Zipline that serve overlapping last-mile use cases; Amazon’s Scout program, an earlier sidewalk-robot effort, was discontinued in 2022. Serve’s public listing, automotive-grade manufacturing partnership with Magna, and large-scale commercial agreement with Uber Eats have positioned it as one of the most heavily deployed sidewalk-robot fleets in the U.S., though the company remains unprofitable and dependent on a small number of large partners, chiefly Uber. With the Diligent Robotics acquisition, Serve also enters the indoor hospital-logistics-robot category, where it competes with other healthcare mobile-robot providers, leveraging shared “physical AI” navigation and safety technology across both its outdoor and indoor product lines.
