Fever secured $35 million from Rakuten Capital, Atresmedia and Accel.

Fever, a Madrid, Spain and London, UK-based company operating a business based on a mobile app for social events raised $35 million.

The investment round was led by Rakuten Capital, the investment arm of Japanese internet giant Rakuten, and included Atresmedia, Accel and Michael Zeisser, the former chairman of U.S. investments for Alibaba Group. Zeisser will also join Fever’s board together with Oskar Mielczarek, partner of Rakuten.

Fever, founded in Barcelona in 2011 by Pep Gomez and led by CEO Ignacio Bachiller Ströhlein and Francisco Hein, developed a mobile app that generates personalized events listings for users and feeds into its Secret Media Network, which also collects user data from the company’s social media channel.

The anonymized data is then analyzed using Fever’s algorithms to help companies plan events like “The Alice in Wonderland MaddHatter G&T” in Hollywood, the Halloween-themed “House of Spirits” in Los Angeles and “Candlelight Concerts,” classical music shows aimed at young audiences. The company now claims 25 million unique users per month across its main markets in London, New York, Paris and Madrid, and plans to use its new funding to expand into new cities.

The company generates 70% of the business outside Spain and is operating a business line, dubbed Fever Originals , which actively uses the data it has to help brands design new leisure experiences. This model, in which Fever charges a commission per user, already accounts for 20% of the company's revenues.

Since founding, Fever raised to over $70 million.
