Between Cultures — Turning differences into performance

Why Partners Work With Us

Because successful transformation requires more than strategy and technology.

Transformation and technology partners lead strategy, technology and implementation. The success of transformation is ultimately determined by whether leaders, teams and business functions take shared ownership of execution.

Between Cultures brings the organisation's inside perspective. While the lead partner shapes the transformation, we help embed it across the organisation.

  1. 01

    Identify hidden alignment risks early

    Identify conflicting expectations and critical stakeholder dynamics before they slow decisions and execution.

  2. 02

    Align business functions around shared decisions

    Align management, business and technology around common priorities and clear accountability.

  3. 03

    Reduce friction across the transformation programme

    Reduce recurring alignment discussions to enable faster, more consistent decision-making.

  4. 04

    Embed change sustainably

    Align new roles, responsibilities and ways of working with the future operating model while building lasting commitment to change.

Who we are

First-hand transformation experience meets international leadership.

We founded Between Cultures because we have not only advised transformation—we have led it ourselves over many years within international organisations.

Our complementary backgrounds combine international leadership, digital transformation, organisational development and entrepreneurship.

Together, we bridge the perspective of transformation partners with the realities inside organisations, where successful execution happens.

Tamara Sommer, founder of Between Cultures

Tamara Sommer · Founder

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 | Facilitator for International Cooperation

My career has taken me across countries, industries and leadership roles—from tourism and aviation to financial services. Along the way, I worked with international teams, strategic partners and senior stakeholders on transformation programmes within complex organisations.

My international experience taught me that transformation rarely fails because of strategy or technology. Success depends on whether people with different perspectives build a shared understanding and take ownership of execution.

That is exactly where I focus today with Between Cultures. I help organisations make different perspectives visible and build the shared understanding that enables stronger collaboration, faster decisions and sustainable performance.

Organisations do not transform through strategy alone. They transform when people turn their differences into a shared way of working.
