It’s the third maker of cross-platform productivity apps Microsoft has acquired recently. It’s clear why 6Wunderkinder was an appealing buy for Microsoft: the service has more than 13 million users, who have created a total of 1 billion to-do list items. A Microsoft spokeswoman declined to share the financial terms of the acquisition. Previous reports pegged the value of the deal between $100 and $200 million. According to Reber’s post, more developments are soon coming for the service, including many new features, an expansion of the partner ecosystem and a push to grow the user base into the “billions of people.” The service’s business model will carry on after the acquisition, and people who pay for a Wunderlist Pro or Business subscription will continue to be charged.Īt least for the time being, it seems like it’s business as usual for Wunderlist as 6Wunderkinder begins integrating with Microsoft following the acquisition. Wunderlist’s existing applications will remain functional, and the company will continue to develop the service from its offices in Berlin. The deal won’t immediately affect any existing Wunderlist users, company co-founder and CEO Christian Reber said in a blog post. It comes highly reviewed by users across platforms.

Wunderlist lets people sync their to-do lists through applications for platforms including iOS, Android, Mac OS, Windows, and the web. Microsoft has confirmed it acquired 6Wunderkinder GmbH, a German startup behind the popular Wunderlist to-do list application.
