Fever, a startup that uses proprietary algorithms to help companies plan events, announced today that it has raised $35 million led by Rakuten Capital, the investment arm of Japanese internet giant Rakuten .

Based in Madrid and London, Fever’s app 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-theme “House of Spirits in Los Angeles and “Candlelight Concerts,” classical music shows aimed at young audiences.
