A world where sustainability is a prerequisite for a company’s right to exist

A heart for SMEs and entrepreneurship.

We believe in the power of small and medium sized businesses to build a more inclusive and sustainable economy. Europe's 25 million small and medium-sized businesses are the backbone of our economy. They create two out of three jobs, provide training opportunities in all regions and sectors, including for low-skilled workers, and support the well-being of society. Together with the SMBs of Europe, we want to use our talents and experience to create a better world for current and future generations.

Making positive impact measurable and transparent for all.

Our Mission

What we do every day

We measure and strengthen our clients’ sustainability performance—and challenge them to communicate their impact with transparency and confidence.

Our Core Values

emoji

All businesses should be a force for good. We promote the values of “business as a force for good”, taking responsibility for people, planet, and economy. We create shared value with all our stakeholders.


emoji

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



emoji

We embrace the spirit of interdependence between people, planet, and economy. We steer away from polarizing debates—because we’re all in the same boat… with 17 holes (SDGs) in the bottom. Let’s join forces and take action!


emoji

Out of many, we are one. We work as a team, creating a platform for each other. We recognize the strength in our differences and proactively support one another in every possible way to achieve our collective goals.



The best ideas must win—no matter where they come from. An idea only becomes valuable when it is written down, backed by data, and shared with the team.

The words we use matter. How we talk about ourselves and others greatly influences how we are understood and resonate with others. The voice of Sustainability Partner is informal, positive, supportive, and inclusive. We strive to uphold these principles in every interaction.



emoji

The way we listen matters. We don’t listen just to respond or judge based on our own perspectives. We listen to fully understand others, to empathize with them, and to grasp what truly drives them.


emoji

Sustainability isn’t about perfection—it’s about reliability. Our stakeholders need to trust us. That’s why we commit to continuous improvement and transparently share our progress with all stakeholders to accelerate change.



B Corp

‍Walking the talk

We don’t just help companies become Certified B Corps—we are one ourselves.
B Corps are for-profit businesses that, alongside financial results, explicitly pursue social and environmental goals.

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 rigor of the certification process helps us understand even more clearly the impact we have on people, planet, and society. And that creates a strong drive to do better. Certification is a means, not an end. It’s a continuous improvement journey toward a more inclusive, fair, and regenerative economic system.

Board Of Advisors
To strengthen the board in fulfilling its mandate, we have included two amendments in our articles of association:
1

One of the company’s objectives is to create a genuine positive impact on society and the environment through its business operations and economic activities..

The interests of shareholders do not take precedence over those of other stakeholders.
2

Advisory Board

From experience, we know that companies are not always in the best position to objectively assess their own actions.

That’s why we have established an Advisory Board. The board challenges us to do even better business and ensures that we continue to commit ourselves to people, planet, and society—while growing as a company.


What our customers say about us

Our clients’ opinions are central to everything we do, and anonymity guarantees their freedom to be honest. That’s why we place great importance on collecting in-depth, anonymous feedback about our services. We continuously measure and improve customer satisfaction, because we believe this is the key to strong, long-term partnerships.
