Thinkfree Partnership with Nextcloud, world’s most popular privacy-focused Collaboration Platform

Headquartered in Germany, Nextcloud develops and provides software for online collaboration and communication, including file storage, chat and video conferencing, email, contacts, and calendar solutions. Its solutions are widely adopted by tens of thousands of private companies, public institutions, and government agencies globally, and are used by tens of millions of users worldwide.

Recently, driven by the growing trend in Europe to reduce reliance on U.S. big tech cloud services and to strengthen digital sovereignty, demand for Nextcloud solutions has been rapidly increasing across Europe and other regions such as the U.S., Canada, Asia, and Latin America. As a result, Nextcloud’s demand in the first half of 2025 has grown more than threefold compared to the previous year, solidifying its position as a strong alternative to Microsoft and Google.

Through this partnership, Nextcloud users can seamlessly view, edit, and collaborate on office documents using Thinkfree’s online office suite, which is fully integrated with Nextcloud’s collaboration platform and highly compatible with Microsoft Office formats.

Thinkfree Office is available as a connector app in the Nextcloud app store, making it easy for users to get started.

Deekay Kim, CEO of Thinkfree, said,

“Nextcloud is a global leader in collaboration platforms, trusted by customers across Europe and beyond. Through this partnership, we look forward to helping businesses enhance productivity in their digital environments while protecting their digital sovereignty together with Nextcloud.”

He added,

“Backed by over 15 years of office software development expertise, Thinkfree offers high compatibility with Microsoft Office formats and features a powerful proprietary document engine that enables fast document rendering and processing. This allows Nextcloud users to enjoy a seamless and efficient document editing and collaboration experience.”

“We’re proud to welcome Thinkfree Office to our growing ecosystem”, said Frank Karlitschek, founder and CEO of Nextcloud. “Together with Thinkfree Office, we’re expanding choice and flexibility for users who demand control without compromise.”
