We help transformative organizations and actors to collaborate better


Quercus Group is an international consulting company for sustainability based in Copenhagen, Nairobi and Singapore. We focus on sustainable trade, regional economic development and social innovation. Our expertise is collaboration, co-creation and how to effectively use it to address the world’s most difficult challenges.

We help organizations, stakeholder and people from government, business and civic society to forge future opportunities, choices and solutions that are unattainable by acting alone.

Our services help get a better understanding of what is going on, how to navigate rapid, far-reaching and unprecedented changes in all aspects of society and how to create effective change by doing it in partnership.

Imagine what we can do together.


A single project can be the beginning of a systemic shift. We help making changes beyond mere optimization.

Since 2012, we supported companies, governments, cities, international agencies, universities and civil society in over 40 countries. Our engagements span days, months or years.

In past and recent projects, we tackled issues related to sustainable and inclusive business, urban development, waste management & circular economy, water & sanitation, climate smart agriculture, mobility, cleantech and cluster development.

We are not bound by the topic and seek synergies across sectors and themes. Foremost, we are driven by the challenge. We care a lot about the process. It turns out the biggest barriers to change, and what might be the strongest enablers of change is process. Our approach and methods support how you get there first and then what it is you are getting to.

Building new impact organizations, projects and alliances from scratch


We try to ensure that what we do is as impactful as possible.

Quercus Group is a consulting company. We thought about saying 'agency' to express the creative and imagining part of our work. We catered to drop the 'consulting', because it shows we do strategic advisory, but it does not reflect our excitement for developing and doing. Since 2012, our work brought us to over 40 countries across continents. We engage from our offices in Copenhagen, Nairobi and Singapore, which makes us also 'international'. Our team shape our interdisciplinary profile bringing together different professional and personal backgrounds. Let us add 'sustainable' or 'purpose-driven' to communicate our motivation and aspiration.

Our story

We also have a basement background. It was 2012 and our first office was in our CEO Nicolai's basement, where our story began building on his experience of establishing Copenhagen Cleantech Cluster, today CLEAN. Primarily, he started Quercus Group to have a more interesting life, and the sense of meaning that comes from being on an epic adventure.

Our name

Yes, it is difficult to pick it up right away. Quercus is the latin name for oak. The tree symbolises the long-term. We take action in the now as our contribution to positive changes that last.

Our mindset

Everyone seems to like lists. Here are eleven attributes describing our mindset: curious, open, empathetic, pragmatic, outcome-focused, imaginative, adaptive, honest, humorous, humble and adventourous.

Our Future

Transformation is not enacted in siloes. No organization can, and perhaps should, tackle the complex issues that society faces alone. For us, this means to grow as a team in number and as people. It means to expand our network of partners and friends. What we would ultimately like to see happen: Collaboration and doing things differently become culture, not approaches.

We like coffee. It is even better if you reach out to work or partner with us.


You will find us to be friendly, open, and curious people. We prefer to meet each other, our partners and our clients on eye-height. "Good things start with a cup of coffee (or tea)," we say, because it helps to build relationships of trust and then we take it from there.

We are even more interested to work and partner with you. Pick your favorite from our team and reach out to start a conversation on how we can help.

Imagine what we can do together.
