Top tech startups in Leeds

Slingshot Simulations

Founded in 2019, Slingshot Simulations is a spinout startup from the University of Leeds. It develops software for digital twins, which are simulations or models that test a product or idea before implementation. Slingshot Simulations aims to help tackle the threats of climate change with “Compass Engine”, a tool that collates both public and proprietary data to simulate and analyse scenarios.

As of 2023, Slingshot Simulations has raised over £3 million in funding.


Another spinout from the University of Leeds, NIQS develops medtech for diabetic individuals. Its technology is unique in being non-invasive, achieved through the use of a material designed by NIQS itself. The interaction between skin and this material is what makes it possible to gain a measurement of blood sugar levels. NIQS plans to take this technology beyond glucose measurement and apply the same techniques to monitor other chemicals.

In 2021, NIQS was selected as a Deep Tech Pioneer by Hello Tomorrow, and voted one of the top three student startups by Creator Fund.

Zest specialises in creating and installing electric vehicle chargers. It offers commerical landowners (and councils) a managed service that delivers revenue but also helps to attract drivers of electric vehicles. Expect a growing number of restaurants, hotels and car parks to take advantage.

Zest’s longer-term aim is to make EV chargers more accessible for everyone, and in doing so encourage more people to use electric cars. The company is supported by the UK Government’s Charging Infrastructure Investment Fund, and recently signed a deal with London’s Hackney Council to install 2,500 EV chargers across the borough.

Platform Kinetics

Platform Kinetics tech company Leeds

Platform Kinetics is an engineering company specialising in custom sensors and software for biotechnology. Its goal is to provide research groups with the technology they need to implement their experimental designs. One example based on something we will all be far too familiar with: lateral flow tests. Here, it worked with Soma Bioscence to create an app that would work with its saliva-based lateral flow device.

With a diverse range of clients, it should be no surprise that Platform Kinetics take a multidisciplinary approach: it has experience in bioimaging, optical techniques, and electronic and software development.

Klaxon is a mass-notification service for companies to quickly notify employees of important news. That doesn’t merely mean SMS messages: it can simultaneously send alerts to voice, email, Microsoft Teams and more. Beyond simple notifications, Klaxon’s software also provides businesses with the ability to select specific groups of employees and notify them across a range of different services.

So, why use Klaxon when you could send out mass comms yourself? It boils down to speed of messaging, reduced complexity, greater efficiency and the overall goal of reducing costs of damages. Bad things happen, so it’s best for affected employees to know about it immediately – no matter where they’re working.
