Top 15 Fastest-growing UK Startups to Watch in 2024

Blog start-ups startups in uk uk

As 2024 starts up we have already identified the future trailblazers, the best tech startups that will set the world ablaze in the upcoming year. We look for the visionaries on the cusp of transforming the tech landscape. Whether they’ve harnessed groundbreaking technology or uncovered innovative avenues for value creation, these pioneers are the architects of tomorrow’s success stories.

We reviewed dozens of interesting, promising UK tech companies across many different industries. We’ve covered companies pursuing the latest technology trends (e.g. AI and sustainability) and those forging a new path in traditional markets (e.g. publishing, beauty care products). It was hard work but we had a lot of fun in the process.

Here are SAGE’s “Top 15 UK Startups to Watch” in 2024. It is a varied list representing, in no particular order, a broad range of innovations, from cyber-security to revenue security, from semiconductors to software.

The one common theme is that these are all promising UK tech companies who are definitely on to something and we’ll be watching them closely come January 1st.

1. Beyond Work

Founder/s: Christian Lanng

Founding year: 2023

Total Funding: $2.5M

The vision of Beyond Work is encapsulated in the question: What if we could redesign computing so that language is also the most powerful way to communicate with computers?

Beyond Work believes that there are fundamental problems with most if not all business software applications. In their view, people serve the software and not vice versa. Interactions based on data entry and clicks make the system smarter in the hope that eventually it will be useful to someone down the line. They have developed a platform that aims to ‘humanize’ software interaction through the utilization of Large Language Models (LLMs). 

The answer to this problem, the company believes, is making software interaction more human by tapping the power of language — our most powerful tool for understanding and communicating. This is where LLMs will come in.

2. Cado Security

Founder/s: Christopher Doman, James Campbell

Founded year: 2020

Total funding: $31.5M

When everyone is putting out the fire, Cado wants to help you catch the arson.

The industry is awash with companies that focus on cloud threat prevention and detection, Cado Security has decided to focus on the next step; incident response. As more data moves to the cloud and more threats target cloud environments, security teams must have the ability to respond efficiently. 

We identified Cado as one of the UK startups to watch because this is the first platform to enable security teams to efficiently perform forensics and incident response in the cloud. By building a cloud forensics and incident response platform, the solution automates forensic-level data capture and processing across cloud, container, and serverless environments. Limitations on time and tools are preventing good security teams from becoming great. Cado helps achieve in minutes what used to take analysts days, so they can get to the root of the problem faster. 

Cado Security empowers security teams with a robust platform that helps them get to the bottom of what happened and perform cross-cloud investigations, container investigations, triage and full disk acquisition, evidence preservation, incident containment and analysis of incident response preparedness. 

3. Fingerprint

The entire organization can make better decisions faster, navigate through changing market environments, and stay ahead of the competition.

5. Gravel AI

Founder/s: Karen Ho and To Hong Chan

Founding year: 2022

Total Funding: N/A

Gravel understands that for suppliers of ingredients to be successful, they need independent visibility and insights into the behavior of the markets they are targeting.

Ingredient suppliers are often insulated from the markets in which their customers operate, obstructing their ability to proactively anticipate threats and opportunities. In markets where ingredients are often highlighted and used to create marketing value, suppliers have a unique opportunity to gain insights into the behavior of those markets and capture valuable business intelligence. Gravel AI generates market data insights on the supply of ingredients in the personal care industry, helping suppliers to thrive in this competitive landscape by staying current with all factors that matter – their current and potential customers, other suppliers, and the end consumers. This unique, highly focused approach put them on our list of UK startups to watch.

Gravel AI enables manufacturers to understand how the market for personal care and beauty makes use of specific ingredients, making it easier for companies to anticipate market trends, identify potential opportunities using ingredient commercial success indicators, and prioritize their existing accounts based on AI-empowered ingredient consumption estimates.

6. Immersive Gamebox

Founder/s: Will Dean, David Spindler

Founding Year: 2018

Total Funding: $42.5M

Immersive Gamebox gives an all-too-literal take on the terms immersive entertainment, augmented reality, and…game box.

Immersive Gamebox is about making immersive experiences more captivating and making augmented reality more realistic. This technology platform is redefining in-person gaming by producing self-contained “gameboxes”, hosted anywhere from entertainment centers to public spaces to offices, where customers can enter the game with their friends. 

The founders are capitalizing on consumer demand for highly interactive, physical entertainment experiences that can be shared with friends. Augmented reality smart rooms, with motion tracking, touch screens, and more, provide an authentic, memorable experience. When they say that they’re on a mission to take immersive entertainment to a whole new level, they’re not kidding.

This startup may seem like “a gaming company’, but there is such a well-thought-out business strategy behind it that the technology is almost an afterthought. The modular nature of the gameboxes allows them to be installed wherever there might be consumer traffic and the broad appeal makes them “people magnets”, which is at the core of the win-win-oriented business case. By encouraging gamers to play in groups, in-person the company fulfills its mission of bringing people together through shared play. 

There is also, however, a commercial imperative: helping venues to capture a generous slice of the social experiences revenue pie, with themed birthday parties, corporate events, and holiday celebrations. Gaming culture is a growth industry and Immersive Gamebox is in a good position to ride that wave.

7. Intrinsic Semiconductors

Founder/s: Anthony Kenyon

8. Libraro

Founder/s: Arsim Shillova and Arion Krasniqi

Founding year: 2023

Total Funding: $2.5M

Libraro is showing that taking a tired, old industry and mixing in the latest technology is a recipe for disruption.

Libraro is using web3 technologies to reshape the publishing industry by bringing together authors, readers, and publishers in a collaborative communal ecosystem to unleash, and simultaneously reward, creativity.

Libraro, acting as a digital literary agent, develops a blockchain-based platform that seeks to disrupt the largely unchanged book publishing industry by connecting undiscovered authors with publishers and a community of readers. Authors get the support and guidance they require, readers get direct access to beloved genres as well as undiscovered gems, and publishers can connect with new writers and diversify their catalogs.

The transparency and democracy of the blockchain give a bigger voice to the readers and more control to creators so authors can find and engage with their audience. This major disruption to the book publishing industry changes the role of the publisher from a gatekeeper to the market that tries to pick winners and losers to a facilitator of the market whose function is to nurture those winners that the market has already identified.

9. Oxa
