Meet the 100 fastest-growing startups in the UK and Ireland

This week at Sifted we launched our third UK and Ireland Leaderboard — a ranking of the 100 fastest-growing startups by revenue-growth across these two countries, as well as a new research report , in partnership with law firm Marriott Harrison. The timing was fortuitous, given all the ‘ Londonmaxxing ’ going on at the moment. The capital looks set to have a very strong first quarter of 2026, at least in comparison to its usual competitors Paris and Berlin, with a lot more deals done and equity raised. On the podcast this week, Amy discusses the findings of the leaderboard — along with why London is ‘in’ again with the tech crowd and why Fuse Energy’s Alan Chang is an amusing person to interview — with her colleagues from Sifted’s Intelligence team, Éanna Kelly and Jonathan Sinclair.
