The Context

Like all companies, Talan seeks to catalyze collaboration within itself. In addition, Talan wishes to strengthen its unity as a group despite distinct entities and a presence on 4 continents, and develop a horizontal organization far from classic vertical hierarchies.

An internal currency, common to all employees regardless of their location or hierarchical role, makes it possible to find a common point among all the actors in the company. It is also a way to allow everyone to better exchange, including between distinct teams, thus affirming a horizontal hierarchy.

More details in the article that I dedicated to Talan Coin.
