We’re corporate veterans on a mission.
We’ve led transformations from the inside, designing strategy, driving change and delivering results. We know it’s not just about shaping systems but shifting mindsets.
Our experience spans executive leadership, consulting, organisational psychology and the realities of leading businesses. We've lived the challenges and learned what works and what doesn’t.
Experiencing the way a human-centred approach drove powerful commercial results inspired us to go all in.
That’s why we founded WITHIN.
Work isn’t broken because people don’t care.
It’s broken because relationships are undervalued.
What we do
At WITHIN, we help organisations unlock performance by putting people at the centre: connecting strategy, human psychology and culture to ensure people and organisations thrive.
-
Are your leaders and teams where they need to be? We help leaders navigate ambiguity, build capability, and lead with clarity, even when the path is messy. WITHIN helps to drive the performance of your teams in service of growing your business.
-
You have a strategy. But is your culture ready to deliver it? WITHIN helps you ask the right questions, create the right conditions, and build the momentum your strategy needs. It turns “soft” culture into a competitive advantage.
-
Too many change programmes burn budget but leave no real impact. WITHIN helps you land mission-critical people initiatives. WITHIN helps co-create transformation roadmaps that build resilience, shift mindsets, and embed new ways of working. No prefab plans. No tick-the-box consulting. Just real change.

Our Team
As business leaders, we have first-hand experience of building and transforming organisations.
Felix Koch and Phil Burgess founded WITHIN in 2023 after years as board-level executives at C Space, part of Omnicom, where they were Joint Managing Directors for EMEA. There they led a culture transformation and a leadership programme that genuinely worked: wellbeing improved, employee pride rose from 57% to 87%, voluntary attrition fell from 33% to 17%, and revenue grew by 30%. Seeing how a human-centred approach strengthened both culture and performance clarified their mission. WITHIN was born.
In 2026, Lillemor Wortley joined as the third co-founder from Munich, bringing 15+ years of international experience in leadership, culture, and transformation consulting, including a decade at EY.
United by shared values and a common vision, the three founders combine complementary skills, deep experience, and the courage to challenge conventional thinking. Today they work with leadership teams at organisations including Takeda, L’Oréal, DNV, Bibby Line Group, Troon, Charité and Ipsos.
Different backgrounds. One belief. Transformation begins WITHIN.
