What is the relationship between Mullvad VPN and the Tor Project?

As a Shallot Level member of the Tor Project membership program, Mullvad has been a long-time funder of the Tor Project.

The Tor Project, Inc. and Mullvad VPN AB maintain a narrowly-scoped technical collaboration to develop Mullvad Browser with the goal of making privacy-enhancing technologies more widely available and mass-surveillance impractical.
