Mission

“Making positive impact profitable, measurable & transparent for everyone.”

A passion for entrepreneurship

We believe in the power of small and mid-sized businesses to build a more inclusive and sustainable economy. Europe’s 25 million SMEs are the backbone of our economy. They create two out of every three jobs, provide training opportunities across all regions and sectors, and contribute to the well-being of society.

Together with them, we want to use our talents and experience to create a better world for current and future generations.

We don’t just help companies become Certified B Corps. We’re a B Corp ourselves!

B Corps are for-profit companies that pursue clear social and environmental goals alongside financial performance. Together, we form a global community that uses the power of business to create a better world. B Corps meet B Lab’s high standards for social and environmental impact. Does that mean we’re perfect? Absolutely not.

The rigorous certification process has given us an even deeper understanding of our impact on people, planet, and society — and that motivates us to keep improving. Certification is a means, not an end in itself. It is a journey of continuous improvement towards a more inclusive, equitable, and regenerative economic system.

Een interview met onze Managing Partner in Trends Magazine

Duurzaamheid. Een kostenpost om af te vinken of concurrentievoordeel? Mooi artikel van Sharon Eeckhout in Trends Magazine over waarom investeren in duurzaamheid écht loont voor kmo’s en middelgrote ondernemingen.

“Denk niet na over een aparte duurzaamheidsstrategie, maar over hoe je je bedrijfsstrategie duurzaam maakt.”

Our Core Values

All companies should be a force for good. We champion the principle of “business as a force for good,” take responsibility for people, planet, and the economy, and create shared value for all our stakeholders.

We drive change. We don’t waste time discussing problems. Instead, we focus all our energy on defining the ideal situation. Then we work backwards to determine what is needed to make that change happen.

We embrace the spirit of interdependence between people, planet & the economy. We steer away from polarising debates. We’re all in the same boat… with 17 holes (the SDGs) in the hull. Let’s join forces and get to work.

Out of many, we are one. We work as a team. We create opportunities for each other to shine. We recognise the strength in our differences. We proactively support one another in every way possible to achieve our collective goals.

The best ideas should win. It doesn’t matter where they come from. An idea only becomes a real idea when it is written down, supported by data, and shared with the team.

The words we use matter. How we talk about ourselves and others has a powerful influence on how we are understood and how we resonate with people. The voice of Sustainability Partner is informal, positive, supportive, and inclusive.

The way we listen matters. Not so we can speak afterwards, or judge what is being said through the lens of our own frame of reference. We listen to truly empathise with others and understand what drives them.

Sustainability isn’t about perfection — it’s about trustworthiness. Our stakeholders need to be able to trust us. That’s why we are committed to continuous improvement and transparently share our progress with all our stakeholders to help accelerate change.

What Our Clients Say About Us

Our clients’ opinions are at the heart of what we do, and anonymity gives them the freedom to be completely honest. That’s why we place great importance on collecting comprehensive, anonymous feedback about our services. We continuously measure and improve client satisfaction, because we believe it is the key to building strong and lasting partnerships.
