| Hannah Skingle

Category: Tech & innovation

There’s no denying it, UK tech startups are on an incredible growth trajectory, and are showing no signs of slowing, with £17.8b of equity investment raised between January and October 2021. 

Despite the double incursion of Brexit and the coronavirus pandemic, and the lockdowns that came with it, the United Kingdom (specifically London) remains the top hub for tech companies in Europe—particularly for those businesses operating in fintech and machine learning. 

As well as access to world-class venture capital funds and angel investors in the Capital, tech entrepreneurs also benefit from a booming startup ecosystem of accelerator programmes and business networks (that gives Silicon Valley a run for its money). So who were the leading UK tech startups in 2021, and which companies should you keep an eye on in 2022?

There are many ways to measure startup success. Here, we’ve ranked the top 33 UK tech companies, based on their total value of venture capital funding received to date. Whilst we can’t tell you if they’ll be the most successful tech startups, this metric does reveal some of the most high-potential businesses in the country. Investors think these tech companies have plenty of growth ahead of them, putting their money where their mouth is and offering them the capital to realise their business plans. So, if you work with ambitious startups and scaleups, then these 33 companies should all be on your radar.
