Robotics Startups: The Leading Private Robot Companies in 2026

Robotics has become one of the hottest areas in technology investment. Advances in AI that transformed chatbots are now being applied to machines that see, move and manipulate objects, an area often called "physical AI". Startups are building humanoid robots, general-purpose robot brains and autonomous systems for factories, warehouses, construction sites and homes, and several have reached multi-billion-dollar valuations within a few years of founding. This guide ranks the private robotics companies in our database by sourced valuation, explains the main approaches and covers the gap between excitement and real-world deployment.

Every company in the table links to a full profile with its sourced valuation, funding history and investors. We include private companies whose main business is building robots or AI that controls robots. Autonomous vehicle and drone companies are covered in separate guides.

The ranking

Humanoid robots

Humanoid robots are designed with a roughly human shape so they can work in spaces built for people. Figure AI is the most valuable private robotics company in our ranking at US$39 billion after a Series C of more than US$1 billion. It develops general-purpose humanoids with its own Helix AI system and is building a factory to produce them. Apptronik in Austin, valued at more than US$5.5 billion in a February 2026 round, builds the Apollo humanoid for logistics and manufacturing with partners including Mercedes-Benz and Google DeepMind. Canada's Sanctuary AI focuses on dexterous hands and general-purpose robots. Our guide to humanoid robot companies covers this category in more detail, including public and Chinese competitors.

Robot foundation models

Instead of building robots, some companies build AI models that can control many types of robots, similar to how large language models power many applications. Skild AI in Pittsburgh, valued at more than US$14 billion after a SoftBank-led round, is developing a general-purpose robot brain. Physical Intelligence, reported at about US$11 billion in 2026, trains models that let robots perform a wide range of manipulation tasks. FieldAI, valued at a reported US$2 billion, focuses on autonomy for robots in construction and industrial environments, where conditions change constantly. These companies are betting that general AI models will make robots far more capable and cheaper to program.

Home robots

The Bot Company, founded by Cruise co-founder Kyle Vogt, aims to build robots that help with household chores. It raised US$300 million in its first year and was reported to be valued at US$2 billion in March 2025, with Bloomberg later reporting talks at more than US$4 billion, although it hasn't publicly shown a product. Home robots are the largest potential market but also the hardest, because homes are cluttered and varied and consumers are price-sensitive.

Why robotics investment surged

Several developments drove the surge. AI models became much better at understanding images, language and actions, making it possible for robots to learn tasks from demonstrations and data rather than detailed programming. Simulation improved, allowing robots to practise millions of times virtually. Hardware components, such as motors and sensors, became cheaper, partly thanks to electric vehicle supply chains. Labour shortages in manufacturing, logistics and care work increased demand for automation. And technology companies such as Nvidia promoted robotics as the next major market for AI chips and software, attracting investors who wanted exposure to physical AI.

The data problem

Language models learned from vast amounts of text on the internet, but there is no equivalent internet-scale data set of robot actions. Robotics companies collect data through teleoperation, where humans control robots remotely to demonstrate tasks, through simulation, and by learning from videos of people. Building large, diverse data sets is one of the biggest challenges and a key source of competitive advantage. Companies with robots deployed in real environments can collect data continuously, improving their models over time.

From pilots to production

Most robotics startups are in the pilot phase, testing robots with a few customers on limited tasks. Moving to large-scale deployment requires robots that work reliably for long shifts, recover from errors without human help, operate safely near people and cost less than the alternatives. Manufacturing robots at scale is also difficult, which is why companies such as Figure and Apptronik are investing in factories and manufacturing partnerships. Investors increasingly ask for evidence of paid deployments rather than impressive demonstration videos.

How robotics companies make money

Robot makers can sell robots outright, lease them, or offer robots-as-a-service, where customers pay a monthly fee per robot including maintenance and software updates. Foundation model companies can license their software to robot makers or operators. Service models align payment with value delivered and lower upfront costs for customers, but require the robot company to finance hardware. The right model depends on customers' budgets and how quickly robots prove their value.

Competition from big tech and China

Large companies are investing heavily in robotics. Tesla is developing its Optimus humanoid, Google DeepMind works on robot AI models, Nvidia provides platforms for robot simulation and training, and Amazon operates hundreds of thousands of robots in its warehouses. Chinese companies, including Unitree and UBTech, are producing humanoids at lower prices, supported by China's manufacturing base and government policy. Startups must compete with these well-resourced players while proving their own products.

Safety and regulation

Robots that work near people must be safe. Industrial robots have long operated behind fences, but mobile robots and humanoids move among workers. Standards bodies are developing safety requirements for collaborative and mobile robots, and companies must demonstrate that their machines stop or avoid people reliably. Home robots raise additional questions about privacy, because they carry cameras and microphones in private spaces.

How to evaluate a robotics startup

Key questions include how many robots are deployed with paying customers, how often they need human intervention, what tasks they perform reliably, the cost per robot and the path to lower costs, and how the company collects training data. For foundation model companies, look at how many robot types and tasks their models support and whether customers use them in production. Teams with experience in both AI and hardware manufacturing have an advantage.

What to watch

Watch commercial deployments and robot production volumes, new funding at higher or lower valuations, partnerships with manufacturers and logistics companies, progress by Tesla and Chinese competitors, and safety standards. Our guides to humanoid robot companies, autonomous vehicle companies and the most valuable AI startups cover related areas.

Key takeaways

Figure AI and Skild AI lead private robotics by valuation, followed by Physical Intelligence and Apptronik. Investors are backing both humanoid robot makers and general-purpose robot AI. The sector's challenge is converting impressive demonstrations into reliable, affordable robots deployed at scale, which will determine whether today's valuations are justified.

Industrial robots versus general-purpose robots

Industrial robots have worked in factories for decades, welding car bodies and assembling electronics with great speed and precision. But they are typically programmed for one task in a fixed setting and kept behind safety barriers. Changing what they do requires engineers and time. General-purpose robots aim to adapt to many tasks and environments, learning from data and instructions rather than detailed code. That flexibility could open automation to the many tasks that are too varied or small-scale for traditional robots, such as handling mixed items in warehouses, assisting in hospitals or doing chores at home. The trade-off is that general-purpose robots are currently slower and less reliable than specialised machines for any single task. Their value depends on doing many tasks well enough to justify their cost.

Robots as a service

Many robotics companies offer robots on subscription, charging a monthly fee per robot that covers hardware, software, maintenance and upgrades. Customers avoid large upfront purchases and can scale up or down, while robot makers earn recurring revenue and maintain close relationships with customers. The model requires robot companies to finance the hardware, which increases their capital needs, but it can speed adoption.
