About us

Nature^Squared is committed to creating a truly sustainable Earth on which people, companies, and societies prosper. According to us, nature is the starting point to reach that goal and biodiversity is the engine behind a planet that can provide us in our needs.

Our story

Nature^Squared is guided by the idea that the way we look at nature is fundamentally wrong. Nature is often seen as an expense and cost-base. The idea that a choice should be made between nature and economy prevails. We believe that nature is essential for us, humans and that our ecosystems represent a tremendous wealth, not only ecologically but economically as well.

We have summarised our vision of the value of nature in a short movie.

A real system thinker, Daan acts as a ‘spider in the web’. Founded Nature^Squared in 2012 together with Erwin, because he is convinced that nature restoration is part of the solution for almost all of the major challenges we are currently facing: climate change, inequality, health, and migration. Daan regularly acts as moderator/facilitator and workshop leader. He was acknowledged as one of the most influential sustainability professionals of The Netherlands, being included on the Sustainable 100, as well as on the Food100 (2017), Young Sustainable 100 (2018, 2017, 2014), and was nominated for the VHG Green Award on Sustainable Tuesday on behalf of Nature^Squared. Daan is professor ‘Innovative Entrepreneurship in Rural Areas’ at the HAS University of Applied Sciences since 2017 and together with Erwin, he published the book ‘Earning a good living with Nature’ (only in Dutch). Daan graduated cum laude as a political scientist with a specialization on International Relations and started his first job at Deloitte (2005-2009).

Always focused on action, Erwin makes a living while improving the world. Erwin is founder and co-owner of Nature^Squared. Erwin’s mission is the creation of products with a positive impact on planet Earth. Erwin cannot think within borders (according to Erwin himself) and thus comes up with unconventional solutions that inspire action, especially within agriculture and within the connection between biodiversity and supply chains. Erwin likes challenges and is creative and also director of his company Sterkur, that manufactures physiotherapeutic products with a positive impact on the planet. Erwin is also appointed professor ‘Innovative Entrepreneurship in Rural Areas’ at the HAS University of Applied Sciences.

Likes to inspire and connect. Tom is an all-round project manager, driven to help teams and projects to reach the next level. Tom’s personal mission is ‘mainstreaming biodiversity’. During his study economics (University of Utrecht), Tom learned how to look at the world systematically and determine which steps organizations need to take to build an economy of impact with nature at its basis. Because of his considerable experience in education and capacity building, Tom knows how to inspire people with his mission on biodiversity and how to train and coach teams and people in achieving (project) goals. Tom has worked at the University of Utrecht and the Dutch Bank and is a member of the advisory board of ‘De Kleine Consultant’ in Amsterdam.

Both striker and flying keep. After performing an impressive internship, Lotte was asked to join Nature^Squared and now combines her master's degree Water Management (University of Utrecht) with working parttime at Nature^Squared to commit her organizational and analytical talents to a greener world. Lotte is not just a scoring striker at field hockey, in the office, she is a team player who gives the finishing touch to score with a project.

Analyst and connector. Iris works on achieving a just and inclusive world and views sustainable agriculture as the crucial link. After her degree on Social Geography (University of Copenhagen), she started working at Nature^Squared. As befits a true geographer, she easily switches between different scale levels and knows how to combine economic, environmental and social questions. Iris brings valuable international experience and mainly works on delivering projects for our corporate clients, with a specific focus on the transformation of supply chains.

Be the change you wish to see in the world. Lorain enjoys working in a solution-focused manner to connect people and nature for a naturally resilient and sustainable future. She is educated in (marine) ecology and ecosystem services, combined with policy and economics courses, in order to understand and act upon the challenges environmental conservation and sustainable development are facing. Before joining Nature^Squared she worked in 8 countries, including conservation work with 3 not-for-profit organisations, such as the World Wildlife Fund for Nature (WWF). She combined analytical skills with 1.5 years of (marine and coastal) field-work in the tropics, in order to understand how strategy translates into practice. At Nature^Squared she is assisting the team with various projects, in order to apply and develop her knowledge and skills, within the Dutch context.
