Astera Énergie
Convention Horizon
1,200 employees, two days, a plenary designed like a show.
The brief
Astera Énergie was bringing all its teams together for the first time after a merger. The challenge: to get 1,200 employees on board with a new corporate project in two days, through a plenary session, workshops and an evening event.
The idea
We built the convention as a story in three acts: an immersive plenary on a 32-metre panoramic screen, staged “field” workshops, then a gala evening where the new identity is revealed in light.
Production
Panoramic LED screen, three-level stage, sets for twelve workshop rooms, technical direction for sound, lighting and video, filming and streaming for 400 remote employees. Coordination of fourteen suppliers.

Installation
Three days of build-up, rehearsals with the speakers, show control throughout the event and overnight breakdown.
They turned a corporate moment into a shared memory. Six months on, the teams still talk about it.
