London, United Kingdom · Venture CapitalBalderton 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.

London, United Kingdom · Venture CapitalIndex Ventures is a globally renowned venture capital firm that originated in Europe and has been instrumental in scaling many of the continent’s top tech companies. Founded in Geneva in 1996 by the Daly brothers and Neil Rimer, Index later opened major offices in London and San Francisco, making it a transatlantic VC powerhouse. Index invests at all stages (seed to growth), though it is especially prominent in Series A/B in Europe. The firm has an extraordinary track record: it was an early backer of Skype (sold to eBay), Last.fm (sold to CBS), Supercell (acquired by Tencent), and MySQL (acquired by Sun) in the 2000s, and more recently of Deliveroo, Adyen, Figma, Revolut, Robinhood and Notion – to name a few. Index’s portfolio spans consumer and enterprise: it has seeded fashion marketplaces like ASOS and Farfetch, scaled up fintech stars like TransferWise (Wise) and Robinhood, and supported open-source and SaaS successes (Elastic, Confluent, Collibra). The firm manages multiple funds (it raised a $3B+ set of funds in 2022) and often co-invests across its early and growth funds to support companies long-term. Index is particularly known for its knack in consumer-facing startups and its ability to spot trends early (e.g., it led Patreon’s Series A in the creator economy space, and Discord’s seed in gaming communication). Partners at Index are a cosmopolitan bunch – with backgrounds ranging from gaming entrepreneurs to investment bankers – and they bring a strong network in both Silicon Valley and Europe. Uniquely, Index also has a life sciences arm (Index Life) that invested in companies like Moderna. In Europe, Index has been among the top three most active VCs by number of unicorns backed. For example, Index led Deliveroo’s Series B in 2014 and remained a major shareholder through its 2021 IPO. Similarly, Index was pivotal in Adyen’s growth (now a ~$50B payments giant). Culturally, Index is known for being founder-friendly and global in outlook – encouraging its European portfolio to expand to the US when needed and vice versa. It also frequently publishes insightful content (e.g., Bernard Dallé’s guides on SaaS metrics or interviews with founders). As of 2025, Index Ventures stands as a gold-standard VC, with a portfolio boasting dozens of IPOs and acquisitions, and a current crop of rising stars across continents.
