Behaviour change
through immersive
experiences
Some things can't be taught. They have to be felt.
Interactive workshops with actors · Award-winning · London · Milan · Berlin
Real change happens under the skin
Real change happens on an emotional level. Our experiences get under the skin, and they're fun. Because people remember what makes them feel alive.
Sidestream is a behaviour change consultancy that trains teams in the room, through live practice with actors. We combine organisational psychology with techniques from immersive theatre. Forget questionnaires, tick-box exercises and passive learning.

What makes us different & where we add value
Most training or e-learning providers deliver outcomes at surface levels 1 & 2.
1
The biased post-event survey
Did you enjoy the training on a scale from 1 to 5? (And most importantly, were the sandwiches any good?)
2
The short-term memory test
Back to school. The dreaded multiple-choice test that you immediately forget. (How many questions can you guess off the bat?)
That is not enough!
We believe in order to drive real behaviour change and deliver real value in organisations, you must go beneath the surface. This is why our method always includes two additional steps.
3
Behaviours
Without behaviours any training is a "tick box" exercise. Change happens through action. That's why we use evidence-based psychological tools and practice-based techniques from the world of immersive theatre.
4
Simulations
Any training that aims to spark behaviour change has to be oriented on real-world applications. That's why we use our award-winning expertise in crafting visceral, realistic and fun simulations, that create lasting impact and memories.

Audience survey, The Accused, 2017
"I think being part of something (as opposed to hearing a traditional lecture on all of these things) makes you much more likely to remember what you've learned."
The judges loved the 'creative approach' to building awareness, describing the event as 'well executed' and 'an excellent mix of theatre and immersive'.
