Please let us know if you need any further information or if you wish to discuss an issue with us or otherwise want to get in touch.

LETZ CERTI is a consultancy based in Copenhagen, Denmark, working globally. We are founded in 2020 by Lars Ludvigsen and Susanne Hacke. We rely on the research activities and business insights which have been created by Jakob Zeuthen and Lars Ludvigsen and communicated in their books on The Butterfly Model. This work has progressed since 2015.

LETZ CERTI can help especially small and medium-sized companies to develop sustainable business strategies and communicate sustainably through well-documented third-party and multi-stakeholder certifications and labelling.

Our services include books, webinars, magazine, surveys, speeches, workshops, exhibitions, training, consulting, mystery shopping, gaming, and apps.

We are open to new co-creation projects. So, please contact us with good ideas and new projects.
