When you need me
When the next step
is not obvious.
At moments of change, another initiative is rarely the answer. Business as usual can be the highest-risk choice.
What matters is clarity on where to play, what to change and how to turn strategy into action.
Repositioning
Has the business evolved — and have customers moved on — while positioning and brand have not? Are strategic choices still being made from the inside out?
Marketing impact
How can brand and marketing create measurable commercial impact — and focus investment on what truly changes customer choice and growth?
Organisational complexity
What needs to be simplified, aligned or redesigned so strategy can actually move through the organisation?
AI & Human
How should the system change when AI becomes part of the operating model — and where must human judgement remain in the loop?
Sustainability
How can purpose and sustainability move from ambition to relevance, trust and business value?
Advisory
Transformation across the levers that drive growth.
Business transformation rarely sits in one function. It happens where positioning, brand, customer experience, marketing, commercial execution, AI and sustainability connect.
And it starts from within.
The hardest shift is often not structural, but a change in perspective and narrative — challenging established assumptions and aligning the organisation around a new direction.
01
Positioning
Shift from inside-out assumptions to a position rooted in customer relevance — defining where to play, what to stand for and why customers should choose you.
02
Brand
Turn positioning into preference, relevance and a brand experience that supports growth — across every point where customers experience the business.
03
Marketing & Commercial
Reconnect product, price, place and promotion with brand, customer experience and commercial execution — and measure what matters for customer choice, growth and return on marketing investment.
04
AI
AI is a system change, not an efficiency programme. Redesign capabilities, decision-making and operating models around where AI creates value, where human judgement must remain in the loop, and what governance leaders and boards need.
05
Sustainability
Move from ambition to business value. Connect purpose and sustainability with customer relevance, trust, innovation and long-term competitive advantage.
Executive experience
Change.
From the inside.
Birgit Berthold-Kremser is a C-level executive and advisor with a track record in business transformation, international growth, brand leadership, AI and sustainability. Her career spans senior global leadership roles at SIEMENS, SWAROVSKI and PEEK & CLOPPENBURG — across B2B, B2C and omnichannel business models, from technology and industry to luxury and retail.
Her work has centred on moments when businesses needed to reposition, revitalise or transform — from global brand strategy and customer experience to commercial effectiveness, organisational change, AI and ESG. Across complex international matrix organisations, strategic direction was combined with hands-on execution to strengthen competitiveness, relevance and long-term growth.
Real transformation happens when strategy, brand and people move in the same direction.

Perspectives
A point of view
matters.
Curated perspectives on the forces reshaping growth, brands and leadership — informed by executive experience and focused on what matters next.
AI is a leadership test.
Technology changes capabilities. Judgement, governance and trust determine the outcome.
Brand is a business lever.
Strong brands create more than awareness — they create preference, orientation, pricing power and growth.
Purpose needs business relevance.
Sustainability becomes powerful when purpose, customer relevance and performance reinforce one another.
