Northzone
Northzone is a prominent European venture capital firm with Scandinavian roots, known for early bets on companies like Spotify and Klarna. Founded in 1996 in Oslo (and now headquartered in Stockholm with a big presence in London), Northzone is an evergreen VC fund that has raised 9 funds to date. It invests from Seed and Series A up to Growth (Series B/C), typically focusing on consumer internet, fintech, and B2B SaaS. Northzone rose to fame as the earliest institutional investor in Spotify – it led Spotify’s $21M Series A in 2008 and remained a major shareholder until IPO. It was also an early backer of Klarna (led the $8M Series A in 2010) and other Nordic breakouts like iZettle (payments, acquired by PayPal) and Avito (Russian classifieds, acquired by Naspers). Over the years, Northzone expanded its geographic focus to include the UK, Benelux, and the US East Coast (they’ve invested in Wallapop in Spain, Personio in Germany, and Secret Escapes in UK, among others). The firm’s investment approach is relatively hands-on – partners often take board seats and leverage Northzone’s network for business development of their portfolio. With approximately €1.5 billion under management, Northzone typically writes initial checks of €2–10M and can follow on with much larger amounts. In 2022, Northzone raised a new €1B+ fund, reflecting growing LP interest in European tech. The team blends operational experience and finance acumen; notable partners include Pär-Jörgen Pärson (who led the Spotify deal) and Michiel Kotting (who sits on Personio’s board). Northzone often leads or co-leads rounds and likes to syndicate with US VCs when scaling globally. Beyond fintech and music tech, they have investments in healthtech (Kry), edtech (Kahoot!), crypto (Sovereign), and more – showcasing a broad thesis of “transformative tech.” Northzone’s steady success over 25+ years – producing multiple billion-dollar exits – has cemented its reputation as one of Europe’s top-tier venture firms, bridging the vibrant Nordic ecosystem with the rest of the continent.
