APALA
Think & do tank for the transitions since 2013
A committed transition intermediary for more than 10 years
Since its creation in 2013 by a group of committed science and engineering students, APALA has evolved into a think & do tank for the transitions. Our mission: to encourage positive cultural change, help identify priority actions and develop effective, coherent approaches.
Our approach is based on:
✔︎ A rigorous scientific approach and a critical mind, to avoid ideas that sound good but aren’t.
✔︎ Identifying sustainable technologies and practices.
✔︎ Training and awareness-raising, to foster an informed transition.
✔︎ Strategic support for impact project leaders, through our Startup Studio.
In September 2024, we made this transformation official at the Nantes Digital Week festival. The event marked a turning point, structuring our new approach around three areas of action.
