2023 was a rough year in tech, and the UK was no exception.
Startups raised around half the figure of 2021’s record-breaking, $38.7bn year — pulling in $18.4bn.
While fundraising troubles have continued into 2024 (figures are currently on track to hit similar levels to last year) there are still several startups scaling at pace.
Like 2023, climate tech dominates this year’s 10 fastest-growing startups, counting four companies among the ranks, following another record year on the fundraising roadshow for the sector. There’s also a fintech, biotech, edtech, foodtech, agritech and a GenAI startup on the list.
Sifted used data from Dealroom to put together the 10 fastest-growing UK startup teams by headcount over the last 12 months. To avoid results being skewed by early-stage businesses making lots of hires while growing quickly, companies have to have raised at least $50m and at least 25 employees to be considered.
1/ Field
HQ city: London
Founded: 2020
Headcount growth over the last 12 months: 175% to 165 employees
The renewable energy infrastructure startup makes it onto Sifted’s fastest growing list for the second year running — after coming in at number five in the 2023 edition.
Founded by now-collapsed energy supplier Bulb cofounder Amit Gudka, Field works with landowners and communities to build battery-based energy storage sites that supply the grid.
The LocalGlobe and Plural-backed startup raised £200m in July 2023 to expand its battery projects in the UK and to move into Europe. The round took Field’s total funding to £240m.
2/ Weev
HQ city: Belfast, Northern Ireland
Founded: 2022
Headcount growth over the last 12 months: 167% to 48 employees
Weev operates an EV charging network across Northern Ireland. It raised a £50m round from Octopus Investments in May 2023 — the country’s largest every VC round, according to Dealroom data.
