Our take
Adevinta Spain is part of the global Adevinta family, which is publicly listed in its native Norway. The company as a whole is one of the world’s largest classified marketplace companies, boasting a portfolio of around 50 brands in over a dozen countries, and employing close to 10,000 people.
The Spanish arm owns a number of the country's top digital classifieds marketplaces including Fotocasa, InfoJobs, and Milanuncios. At a time when larger companies are acquiring scores of eCommerce startups – a concept dubbed “eCommerce rollups” – it’s really interesting that Adevinta seems to have made quite the head start.
Indeed the fact that Adevinta isn’t going after D2C brands, but the marketplaces themselves, is clever. Considering that well over $2 trillion is spent annually on online marketplaces, Adevinta Spain (as well as Adevinta as a whole) is operating from a position of strength in an extremely lucrative market, especially since a buyout by Blackstone and Permira in November 2023 was initiated. This will further bolster Adevinta's position as a market leader under strong new ownerhsip.
