Stian Vatne earned the first Norwegian Clark Gracie blue belt in 2016, the year Norway formally connected to the Clark Gracie line, and was promoted to purple in 2019. Together with Daniel Snekvik he co-owns Gracie Allegiance Norway and Clark Gracie Jiu-Jitsu Norway, the organisations that bring the Clark Gracie affiliation into the country.
His competition profile sits on the Norwegian IBJJF-affiliated circuit rather than the international ADCC trials route, but his structural role inside the country is significant: each Clark Gracie belt promotion in Norway over the past decade has passed through the system he and Snekvik built.
For a smaller, lineage-specific community within the broader Norwegian BJJ scene, Vatne is one of the original pillars.
