Despite Brexit-related shifts, the UK continues to produce more unicorns than any other European country. The directory currently lists 306 organisations across 20 cities.

Headquartered in London with roots in Stockholm, Atomico focuses on backing ambitious tech founders across Europe at Series A and beyond.

Atomico has invested in companies spanning fintech, deep tech, software, and consumer internet. Notable successes include Klarna (the Swedish fintech giant), Supercell (Finnish gaming, acquired by Tencent), Graphcore (UK AI chips), and MessageBird (Netherlands communications platform). Atomico was also an early backer of Stripe in the US and Viagogo. The firm is known for publishing the annual “State of European Tech” report, reflecting its thought leadership in the ecosystem. In terms of investment size, Atomico typically leads or co-leads Series A–C rounds with cheques of $5–$50 million, and it has the capacity to follow-on through later stages. It closed its fifth fund of $820 million in 2020 and a $1.2 billion fund in 2022, underscoring investor confidence in European tech. Atomico’s team includes partners with experience at Google, Uber, Spotify, and more – providing operational support to portfolio founders.

Atomico’s influence is evidenced by the fact that as of 2025 it has produced five IPOs and multiple $10B+ exits in Europe.

Balderton Capital
Balderton Capital is one of Europe’s most established venture capital firms focused on early-stage technology companies. Based in London, Balderton was founded in 2000 as the European arm of Benchmark Capital and became independent in 2007. It has since raised ten funds dedicated to European startups, with over $4 billion in assets under management. Balderton primarily invests at Series A, typically leading rounds of $5–15 million and taking significant minority stakes. The firm’s portfolio spans a wide range of sectors – from fintech and marketplaces to SaaS and gaming – reflecting Europe’s diversity. Notable investments include Revolut (fintech, which Balderton backed at Series A), The Hut Group (UK e-commerce, now public), Darktrace (cybersecurity, IPO 2021), MySQL (acquired by Sun Microsystems), Citymapper (urban transport app), GoCardless (payments) and Vestiaire Collective (fashion resale). Balderton has consistently been among the most active Series A investors in Europe; in 2022 it deployed capital into 20+ new companies and many follow-ons. The firm is known for its strong founder support and an ethos of “teamwork” – all partners share carry evenly, which encourages collective input on portfolio companies. General Partners like Bernard Liautaud (founder of Business Objects) and Suranga Chandratillake (founder of Blinkx) bring operator experience. In recent years Balderton also launched a liquidity fund to buy secondary shares from European tech founders and early employees, reflecting a maturing ecosystem. The firm has also been vocal on issues like startup diversity and European tech sovereignty. With successes such as Revolut’s rise to $33B valuation and Darktrace’s IPO (Balderton held ~18% at listing), Balderton has proven that European VCs can deliver world-class returns. It continues to invest actively across Europe – from Stockholm to Tel Aviv – aiming to partner with founders “with global ambition.” In the constellation of European VC, Balderton Capital is often mentioned alongside Accel and Index as the top choice for Series A funding, thanks to its track record and deep network built over two decades.
