10 UK Startups to Watch in 2023 and Beyond

Sarah Cheesman, 28 September 2023

The UK has long had an enviable history of successful startups, from finance firms such as Revolut and Starling Bank, to B2C food and retail companies such as Deliveroo and ASOS. Although Startup Genome reports that around 90% of startups fail within their first three years of business, those that are successful represent a huge opportunity for investors, venture capitalists and others.

This makes keeping up to date with what’s going on in the UK startup market incredibly important, giving you the chance to find out about startups that are doing particularly well before they reach the big time.

In this article, we’re taking a look at 10 of the most exciting startups companies in the UK (at the moment and how we can help you track these—and more—going forward.

What is a startup company?

To put it simply, a startup is a company that’s in the initial stages of business. This type of business is often founded by one or more entrepreneurs to develop a product or service that they believe there is a demand or a particular gap in the market for. Startups will generally have high costs and limited revenue, which is why they often seek assistance from investors to help them grow through the initial stages.

Is every small company considered a startup?

Not all small businesses in the UK are considered startups. There are many companies out there that will have limited growth opportunities that will always be considered small, such as single restaurants, or some professional services firms.
