Who We Are

Meet the
Behaviour Change
Consultants

Founded by an organisational psychologist and a systemic coach, combining science, theatre, and human insight to create lasting change.

"I don't think learning should be passive or dull. The world is changing quickly, and to grow, we need to stay active, curious, and ready to think in new ways."
, Ben Laumann, Co-Founder

Our Mission

Real Change, In 52 Seconds

A short message from our founder on what makes Sidestream's behaviour-change methodology different, and why it works.

Our Story

Where Science Meets Theatre

Sidestream started with a frustration. We'd both spent years watching well-meaning training programmes leave no trace. People nodded in the room and forgot by the weekend. The science said one thing, the slide deck said another, and the slide deck always won. We were tired of watching it.

So we built something different. The rigour of organisational psychology and the craft of immersive theatre, two worlds that almost never meet, in the same room. The result: live, scripted behavioural experiences participants are still describing months later. How we think · what it does in practice.

Based in London, Milan and Berlin (hybrid). Working across Europe and globally, public sector to scale-ups, healthcare to creative industries. Browse six sector case studies or our six tailored programmes, or book a 30-minute call to find out if we're the right fit.

What We Stand For

Our Values

🎭
Experiential First

We believe people learn through doing, not watching. Every programme we design puts participants at the centre of the action.

🔬
Evidence-Based

Everything we do is grounded in behavioural science, organisational psychology, and real-world research, not fashionable buzzwords.

🌍
Radically Honest

We tell you what we honestly think will work for your organisation. If we're not the right fit, we'll say so.

🤝
Inclusive by Design

We don't design for the majority and hope it works for everyone. Inclusion is built into every experience we create.

Lasting Impact

We're not interested in one-day wonders. Our programmes are designed for sustainable behaviour change that outlasts any single session.

🎯
Bespoke Thinking

No two organisations are alike. Every programme we design is built around your specific people, culture, and challenges.
