Summary
Nimble Robotics builds AI-powered, general-purpose warehouse robots and operates fully autonomous e-commerce fulfillment centers around them, positioning a single “superhumanoid” mobile-manipulator platform as a replacement for the many specialized machines that typically make up a warehouse automation system. Founded in San Francisco in 2017, the company reached a $1 billion valuation in October 2024 after FedEx led a $106 million Series C investment and struck a commercial alliance to scale FedEx’s own fulfillment operations using Nimble’s technology.
Company Story
Founder and CEO Simon Kalouche started Nimble Robotics in 2017 after graduate research in robotics and AI, aiming to build a single general-purpose robot capable of performing all of a warehouse’s core physical tasks rather than requiring separate machines for storage, retrieval, picking, packing, and sorting. The company built out its early operations and technology with a $50 million Series A in March 2021, led by DNS Capital and GSR Ventures, followed by a $65 million Series B in March 2023 led by Cedar Pine, bringing total funding to $115 million as Nimble worked toward a nationwide network of autonomous fulfillment centers serving e-commerce and omnichannel brands (Business Wire; SiliconANGLE).
In September 2024, logistics giant FedEx announced a strategic alliance with and investment in Nimble to scale its FedEx Fulfillment service across North America using Nimble’s autonomous third-party-logistics (3PL) model. That relationship culminated the following month in a $106 million Series C round led by FedEx and co-led by existing investor Cedar Pine, valuing Nimble at $1 billion and bringing its total funding to $221 million (FedEx Newsroom; Business Wire). By 2026, FedEx had formalized a broader “multi-vendor robotics” strategy for its supply-chain operations, using Nimble’s autonomous fulfillment infrastructure alongside other automation partners such as Berkshire Grey and Dexterity rather than building proprietary robotics in-house (CXTMS).
Founders
Simon Kalouche founded Nimble Robotics and serves as CEO. He holds a B.S. from The Ohio State University and an M.S. in Robotics from Carnegie Mellon University’s Robotics Institute, where he developed some of the first low-cost quasi-direct-drive (QDD) actuators — technology he says helped catalyze a subsequent generation of low-cost dynamic legged robots, including MIT’s Mini Cheetah and Unitree’s quadrupeds and humanoids. Before founding Nimble, he was a PhD student in Stanford’s Vision and Learning Lab, advised by Fei-Fei Li, researching imitation learning using data from teleoperation and upper-body exoskeletons (Simon Kalouche personal website).
Nimble’s board has included prominent robotics and AI figures, among them Boston Dynamics founder Marc Raibert, Google X and Waymo founder Sebastian Thrun, and Fei-Fei Li, Kalouche’s former Stanford PhD advisor and a widely cited AI researcher, who has publicly described Nimble’s approach as combining large-scale data collection, state-of-the-art AI model training, and custom mobile-manipulator hardware engineering.
Products
Nimble’s core product is a proprietary general-purpose mobile-manipulator robot — which the company markets as a “warehouse superhumanoid” — designed to perform all core fulfillment-center tasks with one hardware platform: storage and retrieval, picking, packing, sorting, and kitting. Nimble pairs the robot with a cloud-based logistics and AI platform that the company says allows fulfillment centers built around it to operate with a fraction of the cost and system complexity of conventional warehouse automation from competitors like Symbotic, while supporting round-the-clock operation and same-day shipping cutoffs (Nimble; Simon Kalouche).
Nimble operates its own network of fulfillment centers on behalf of e-commerce and retail customers — including facilities in the San Francisco Bay Area, Dallas, and Trenton, New Jersey, with further sites planned in 2026 — rather than solely selling robots for other companies to run themselves, a model closer to a fully autonomous third-party logistics (3PL) provider than a traditional robotics vendor.
Funding
Nimble Robotics has raised approximately $221 million across three priced equity rounds: a $50 million Series A in March 2021 led by DNS Capital and GSR Ventures; a $65 million Series B in March 2023 led by Cedar Pine; and a $106 million Series C in October 2024 led by FedEx and co-led by Cedar Pine, which brought the company to a $1 billion valuation. Other investors across these rounds have included Accel, Breyer Capital, and Reinvent Capital, along with individual backers such as AI researcher Fei-Fei Li (Business Wire).
Partnerships
Nimble’s most significant partnership is with FedEx, which became both an investor and a commercial customer in September 2024, using Nimble’s autonomous fulfillment infrastructure to scale FedEx’s own Fulfillment service for e-commerce and omnichannel brands across North America. By 2026, that relationship had evolved into one piece of a broader FedEx strategy of partnering with multiple robotics vendors — including Berkshire Grey for bulk trailer unloading and Dexterity for manipulation-focused picking and packing — rather than relying on a single automation provider (CXTMS). Nimble has also named e-commerce brands including Hanacure, Adore Me, and iHerb among the customers it has served through its fulfillment centers.

Market Context
Nimble competes in the warehouse and logistics automation market against both large incumbents like Symbotic, which builds automated storage-and-retrieval infrastructure for major retailers, and other AI-robotics-focused fulfillment specialists such as Berkshire Grey and Dexterity, both of which are also FedEx partners as of 2026. Nimble’s core differentiation is its bet on a single general-purpose robot handling the full range of warehouse tasks, rather than a suite of task-specific machines; whether that generalist approach ultimately proves more cost-effective and reliable at large scale than more specialized systems remains an open competitive question in the broader warehouse-robotics category. Nimble’s operating model as a full-service, autonomous 3PL provider — running its own fulfillment centers on behalf of customers rather than solely selling hardware — also distinguishes it from robotics vendors that sell or lease equipment for customers to operate themselves.
Source Notes
This profile draws on Nimble Robotics’ own website, founder Simon Kalouche’s personal website, contemporaneous Business Wire press releases and SiliconANGLE and Reuters reporting on Nimble’s funding rounds and FedEx alliance, FedEx’s own newsroom announcement, and CXTMS’s analysis of FedEx’s 2026 multi-vendor robotics strategy. Some sources describe the company’s founding year as 2017 versus “around 2018”; this profile uses 2017, consistent with the company’s own materials and the majority of third-party trackers. Nimble has not published a detailed, itemized breakdown of individual customer revenue or fulfillment-center performance, so descriptions of its operational scale and cost advantages reflect company and partner statements rather than independently audited figures.
