We collaborate more closely
Partnership is everything. Whether that’s working with your internal teams or other consultancies. We don’t play politics; we always make sure the whole is greater than the sum of the parts.
We think more flexibly
We start every project with an open mind and we always work on your terms. It’s never about what’s best for us. It’s always about what’s best for you.
We make change more enjoyable
We take your project seriously, focus on the possibilities and return on investment, but never pass up on the opportunity to make working together more engaging and enjoyable. A little perspective goes a long way.

Six – Strategy Activation Partner
Making strategy human is what turns plans into progress.
Six works with enterprise organisations to close the gap between strategy and activation, helping leaders bring transformation to life in a way people understand, believe in and act on.
Strategies rely on logic. Activation relies on people.
Real change happens when employees connect emotionally to the story of change, see their role in it and feel able to move in the same direction. We help leaders define and communicate that story, create meaning, and design the interventions that move people from awareness to adoption.
We make change stick by making it human.
Through narrative, language, leadership behaviour and meaningful employee experiences, we shift mindsets, build alignment and create the momentum every transformation needs. Our work builds confidence, reduces friction and helps change land in a way that lasts.
6 ways we help:
- Strategic narratives – turning complex plans into clear, compelling stories people act on.
- Leadership alignment – uniting leaders behind one message, one direction, one voice.
- Behaviour change – shifting mindsets and habits to make change stick.
- Culture activation – bringing purpose, values and behaviours to life across the organisation.
- Employee experience & communication – designing moments that give people clarity and confidence through change.
- Transformation mobilisation – equipping teams to create momentum and reduce friction at every stage.
TransparentChoice: Enabling Strategy Execution at Scale
TransparentChoice helps senior leaders solve one of the hardest problems in business: turning strategy into results. For CEOs and transformation offices, the challenge isn’t creating strategy, it’s executing it when resources are limited; priorities compete, and change never stops.
