Friends of the collective
Guillaume helped launch Campaign Accelerator in 2016 after running people-powered mobilisation campaigns for more than 8 years: beginning at Doctors Without Borders, then launching the global citizens’ movement All Out for LGBTQI rights. All Out was based in New York and inspired by the latest engagement techniques developed by the Barack Obama’s campaigns.
Since moving on from the Accelerator, Guillaume has launched 4 different podcasts and now offers coaching to help self-employed people get unstuck and achieve their mission.
