AI and Robotics Companies in Bristol: The 2026 Showcase

There are more AI companies in Bristol than most people realise. The city doesn't shout about it, but it's one of the best places in the UK to build AI and robotics. Chips designed here run machine learning around the world. Drones built here inspect wind turbines on their own. The UK's most powerful supercomputer sits on the edge of the city.

In a short history of AI in Bristol I covered how the city got here, from the transputer to Isambard-AI. This post is the present day: the AI and robotics companies doing interesting work right now, what each one does, and where to find them.

How this list was put together

Last updated: November 2026

There's no official register of AI companies in Bristol, and the online directories disagree with each other and go out of date fast. So every company here has been checked: its website works, its main base is in Bristol, and it actually builds AI, robotics or the hardware they run on, rather than just mentioning AI on its homepage.

That means some well-known names aren't here. Some have closed, been bought or moved their headquarters elsewhere. If you know a Bristol company that should be on the list, let me know and I'll take a look. I'll keep this page updated.

AI chips and compute

Graphcore

Graphcore designs processors built specifically for machine learning, which it calls IPUs (Intelligence Processing Units). Founded in Bristol in 2016, it became one of the UK's best-known startups by taking on Nvidia directly. SoftBank bought it in 2024, and it kept its Bristol headquarters and team.

XMOS

XMOS is a University of Bristol spin-out from 2005 that makes low-power processors for smart devices. Its chips have powered voice processing in smart speakers, and its focus now is edge AI: running AI directly on small devices instead of sending everything to the cloud.

YellowDog

YellowDog solves a less glamorous but very real AI problem: getting hold of compute. Its platform schedules and provisions computing power across AWS, Azure, Google Cloud, Oracle and on-premise machines, so teams running AI, research and financial workloads can find the capacity they need without being tied to one provider.

Robotics and autonomous systems

Perceptual Robotics

Perceptual Robotics uses drones and AI to inspect wind turbine blades automatically. The drone flies the inspection, and AI analyses the images to find damage, which is faster and safer than sending people up on ropes. It was founded by University of Bristol alumni and developed through the Bristol Robotics Laboratory's incubator.

Open Bionics

Open Bionics makes the Hero Arm, a 3D-printed bionic arm with multiple grip patterns, designed to be affordable and to look good rather than hide away. It's one of the Bristol Robotics Laboratory incubator's biggest success stories, and a great example of robotics improving people's everyday lives.

Insphere

Insphere solves a problem most people never think about: industrial robots aren't actually that accurate. Its sensor systems track exactly where a robot is in real time, so robots can do precise manufacturing work in sectors like aerospace and automotive. It's based at the Bristol & Bath Science Park.

iCOMAT

iCOMAT is a University of Bristol spin-out that uses automated, robot-driven manufacturing to make very light composite structures for aerospace and automotive. Its process can steer carbon fibre in curved paths, something traditional methods struggle with.

Sensing and human-machine interfaces

Ultraleap

Ultraleap started life as Ultrahaptics, a 2013 University of Bristol spin-out that used ultrasound to let you feel things in mid-air. In 2019 it bought the US hand-tracking company Leap Motion. Today its computer vision tracks your hands so you can control digital worlds naturally, without a controller.

Altered Carbon

Altered Carbon is giving machines a sense of smell. It combines graphene gas sensors with AI to build a "digital nose" that can detect chemicals and scents, with uses from reducing food waste to monitoring air quality.

AI in health and biotech

CellVoyant

CellVoyant is an AI-first biotech company spun out of the University of Bristol in 2021. It uses AI and live-cell imaging to predict how stem cells will develop, helping companies that make cell-based therapies get better results, faster.

Research labs

Bristol's companies grow out of a strong research base. These are the labs worth knowing.

Bristol Robotics Laboratory

The Bristol Robotics Laboratory is a partnership between UWE Bristol and the University of Bristol, and one of the largest robotics research centres in the UK. It works on everything from assistive robots for healthcare to swarm robotics, and its hardware incubator has launched several companies on this list.

Bristol Centre for Supercomputing and Isambard-AI

The University of Bristol's Bristol Centre for Supercomputing runs Isambard-AI, the UK's most powerful supercomputer, launched in 2025. Researchers and companies across the country use it to train and run AI models that would be impossible on normal hardware.

Toshiba Bristol Research and Innovation Laboratory

Toshiba's Bristol lab has worked in the city since 1998 on AI, digital technologies, wireless and networking research, in close partnership with the University of Bristol.

Bristol Digital Futures Institute

The University of Bristol's Bristol Digital Futures Institute brings together researchers, businesses and public bodies to work on how digital technology, including AI, shapes society.

Where Bristol's AI startups get started

If you're starting an AI or robotics company in Bristol, these are the places that can help:

• SETsquared Bristol is the University of Bristol's business incubator, part of a partnership often ranked among the best university incubators in the world.
• Science Creates provides lab space and investment for deep tech startups, through its venture fund SCVC.
• The BRL Hardware Incubator supports robotics and hardware startups with workshop space and access to the lab's experts.

AI companies in Bristol at a glance

And a small one: Digital HQ

I'd be leaving out a Bristol AI company if I didn't mention mine. Digital HQ builds custom software and AI agents you can actually see into: you control the rules, you connect them to your own systems, and they only take the actions you've allowed. We're a long way from designing chips, but we're working on the part of AI most businesses actually need: making it useful, safely, in day-to-day work.
