If 2024 was the year of AI, 2025 was the year of AI agents. Investors went wild for them, with record amounts of funding flowing into the sector — and one company, Sweden’s Lovable, capturing hearts and headlines. 

Over the past 12 months, its valuation has skyrocketed, recently reaching $6.6bn, while founder Anton Osika has taught his fellow CEOs a thing or two about how to engage with investors, potential hires and customers on social media. 

Aside from Lovable, Revolut remained eagerly watched by everyone in the industry — rolling out a seemingly endless stream of new products, from private banking to mobile plans, and making headlines for hitting a $75bn valuation, keeping schtum about where and when exactly it might list and still not having its full UK banking licence

2025 was also the year that the narrative around European tech took an unexpected turn for the optimistic. EU Inc gained momentum (while the hurdles facing it also increased), hackathons picked up steam across the continent (perhaps none so well-marketed as those from Project Europe) and several European scaleups cemented their positions as category leaders, from Oura to Vinted to Bending Spoons

Less upbeat was the news around climate tech (with funding plummeting, bankruptcies mounting and founders pivoting to ‘resilience’), European tech media (with stalwarts TechCrunch and The Next Web laying off teams) and VC fundraising (remaining muted). 

There was also drama in droves: the Nato Innovation Fund had a tumultuous year; the ‘996’ approach found its fans and its critics; and once-hot AI companies began to run into trouble as competition mounted.

Can 2026 be equally lively? I suspect so. 

Read on for Sifted’s most-read stories of 2025.

Scoop: Revolut to take on American Express with move into reward credit cards & Scoop: Revolut targets wealthy clients with move into private banking

This was the year that Revolut began seriously taking on the finance industry’s goliaths.

Exclusive: The Family cofounder Oussama Ammar ordered to pay £6.5m in damages

The long-running fight between the cofounders of French startup accelerator The Family raged on. In April cofounder Oussama Ammar was found liable for fraud and breach of fiduciary duty against the organisation by a UK court. Daphné Leprince-Ringuet had the exclusive — and the backstory. 

UK offers ‘laughable’ £80k salary for leading role in AI sovereignty plan

The UK government leant into tech and AI more than perhaps ever before — announcing a grand AI plan at the start of the year (and committing £2bn to it in the summer), appointing as advisors numerous figures from the startup world, including Alex Depledge and Octopus’ Greg Jackson, and being vocal about its ambitions to move even faster when it comes to adopting AI. 

But it also had its fair share of blunders, facing pushback for rumoured plans to introduce an exit tax (which did not transpire) and for posting a job ad for a key AI role with a “laughable” salary.

The NATO Innovation Fund has had its ups and downs, including the departure of four out of five of its original investment partners, allegations of potential conflict of interest surrounding its now former-chair Klaus Hommels and a legal dispute over pay with one of those former partners. Speaking on the Sifted Podcast in December, Fiona Murray, chair and former vice chair of NIF, addressed the challenges the organisation has faced so far — and discussed the work that remains to be done in Europe to prepare for the “extremely real” threat posed by Russia.
