WHY ORGANISATIONS WORK WITH US
Because transformation requires the ability to execute.
Our Execution Alignment Assessment reveals strengths, critical gaps and where targeted action can make the greatest difference.
As an independent Alignment Partner, we resolve critical differences and turn Assessment insights into shared decisions, clear ownership and coordinated execution.
Who we are
First-hand transformation experience from inside organisations.
We founded Between Cultures because we have worked inside the organisations where transformation has to become operational.
Our backgrounds combine international leadership, digital transformation, organisational development and entrepreneurship, including more than a decade of leadership and digital growth experience in financial services.
This first-hand perspective helps us recognise where internal alignment breaks down and what it takes to turn it into execution.
Tamara Sommer · Founder | Business Strategy & Operational Excellence
Throughout my career, I have been guided by clarity, structure and building organisations that last. I have always been fascinated by simplifying complexity, creating direction and turning ideas into organisations that work.
Building and leading my own company reinforced this belief. Sustainable success is not created by vision alone, but through clear processes, thoughtful planning and an environment where people take ownership and grow together.
That belief now forms the foundation of Between Cultures.
While we help organisations strengthen collaboration across different perspectives, my focus is on creating the structures that make successful execution possible. From strategy to operational excellence, I ensure that Between Cultures lives the same principles we recommend to our clients.
I believe sustainable performance is built on strong foundations.
When clarity, structure and trust come together, people create lasting impact together.
Massimiliano Grieco · Co-Founder | Digital Transformation Leader | Business Strategist | Cross-Cultural Facilitator | Professional Coach
My career has taken me across countries, industries and leadership roles — from tourism and aviation to more than a decade in financial services, leading digital growth, cross-functional teams and complex initiatives involving business, technology and external partners.
Working across international organisations taught me that transformation rarely fails because of strategy or technology alone. Execution breaks down when leaders and functions bring different perspectives to priorities, responsibilities and decisions without aligning them.
That is where I focus with Between Cultures: making those differences visible, enabling the decisions required for alignment, and translating them into clear ownership and coordinated execution.
Organisations do not transform through strategy alone. They transform when different perspectives become a shared way of executing.

Every transformation is unique.
