THE EXCHANGE is a NNRRTV program for growth across the DACH* region.
Imagine a Europe where its centers no longer compete but align. Berlin and Vienna have always been counterparts with different speeds, different cultures, different perspective on what really matters. For centuries, they have been circling each other, competing for relevance, influence and leadership.
Operating out of these two capitals, NNRRTV now runs a program that reconnects what has grown apart. People, markets, organisations and regions are more fragmented than ever. Not because of a lack of ideas but a lack of connection between systems. We believe growth no longer happens within markets. It happens between them.
Designed for executives, THE EXCHANGE works at this intersection, aligning strengths, translating perspectives, connecting dots—and turning that into real movement. It operates across the three layers:
1 ACCESS: curated introductions, opportunities and executive-level connections.
2 STRATEGY: Identity & direction, positioning, market entry and organizational development. Grounded in real networks.
3 BUILD: From go-to-market structures to ecosystem setups and ventures.
It is not about access alone, not about strategy alone. It is about connection, translation and execution. On eye level, at speed, across markets.
Who are we? THE EXCHANGE is led by a small core team with deep experience across Germany and Austria. Different backgrounds, shared perspective.
Christian Barthélémy (Berlin): former CEO of Vattenfall Germany, bringing top-level corporate leadership and network.
Christoph Zinganell (Vienna): builder and operator, with a strong track record in energy and transformation (e.g. Collective Energy).
Thiemo Puettmann: strategist and partner of NNRRTV, working at the intersection of identity, direction and execution.
We operate as a tight core and extend through a curated network of partners, operators and specialists across the DACH region. This allows us to go far beyond strategy if needed: from positioning and market entry to building structures, ventures and teams on the ground.
