About TagSpaces

Our Mission​

TagSpaces exists to give people full control over their digital files — without cloud accounts, without proprietary databases, and without vendor lock-in. We believe your files should be organized, searchable, and accessible on your terms, not on the terms of a some service.

In a world where most productivity tools require you to upload your data to someone else's server, TagSpaces takes the opposite approach: everything stays on your device, in standard file formats, readable by any application. Your notes are Markdown files. Your tags are stored alongside your files. Your data is yours — today, tomorrow, and in 20 years.

The Founder​

The project was initiated in 2012 by Ilian Sapundshiev in Munich, Germany. Ilian holds a master's degree in computer science and computational linguistics from the Technical University of Munich — a background that directly shapes how TagSpaces approaches file organization, metadata, and search.

In 2015, he founded TagSpaces GmbH to focus full-time on the development of TagSpaces and derivative products. The company remains independent, self-funded, and based in Munich.
