We are starting with a small but super engaged core team, supported by experienced and equally passionate freelancers. Three decades of sustainability strategy background combined with project management skills, digital and marketing experience, fresh ideas straight from university, and a common interest in creating positive impacts are essential ingredients to the PI mix.

We are fun to work with, smart, sometimes even nerdy, thinkers, analyzers, innovators, marketeers… and we like to challenge ourselves and others.

THE PI TEAM

Martin new

“From voluntary engagements to building a career advising organizations, sustainability has been my life’s mission for almost 30 years. I truly believe that the way to a sustainable economy is a thoughtful integration into business strategies, while challenging the (political) conditions around it. I founded positive impacts (PI) to focus on further developing viable concepts that will support organizations on that path, leveraging my experience and network to maximize ‘positive impacts’.”

Martin G. Viehöver
Founder & CEO

Antje Weiruss

“Finding pragmatic, customer-centric solutions and bringing them to life has always been ‘my thing’ in my career so far. I coordinated digital and cross-functional project teams throughout a big corporation. It’s what I’m good at and what I like doing. My personal goal for 2020, however, was to dedicate more time to things with more meaning – or more positive impacts. When Martin asked me to join the positive impacts project, it didn’t take me long to say yes.”

Antje Weiruß
Chief Digital Officer

Carla mudeno

“The climate and biodiversity crises require multi-stakeholder ambition to be tackled with the given urgency. Through my research as climate change ecologist with focus on natural capital valuation, as well as through my professional experience at a Big 4 audit firm, I have learnt that the corporate and financial sector play fundamental roles in leveraging positive impacts for the people and the planet. I am excited to be a science communicator at PI’s team and contribute to informed decision making among its clients.”

Myrna van Vliet

“Creating a thriving tomorrow by combining business and sustainability is what excites me. Being in the final year of International Business Administration at Rotterdam School of Management, I got selected for the sustainability minor. This sparked my interest to further deepen my knowledge on this topic. When the opportunity came along to work with the positive impacts team on integration of ESG into business strategies, I had to accept it and step aboard!”

Anita Demiri

“I am constantly looking for ways to further expand my knowledge in sustainability and have the desire to be part of the pioneers who want to change the world. Being a master’s student in International Business and Sustainability at the University of Hamburg has already given me a good sense of what this means for the business world. Working with the positive impacts team will help me contribute to an actual change.”

Visiting Consultant

Max Gaber

“Driven by the ambition to contribute to a better tomorrow, I decided to branch out into the vast topic of Climate Change. Studying the eponymous master’s degree in Copenhagen and Berkeley, I cherish the aspiration to involve data science technologies in corporate sustainability efforts. How can we use those immense possibilities to establish lasting societal impacts? I am excited to have found with PI an opportunity to create those innovative solutions for our clients.”

Lukas

“Studying social and political sciences, I focused on environmental and climate policy from the outset. In doing so, the relationship between legislation and economy was often discussed from a political point of view, although corporations and business should remain at the center of these discussions. That’s why I want to deepen my understanding of how businesses can best use their resources and take initiative to work responsibly. Working in the PI’s team will not only help me further develop my existing knowledge in this field but will also give me the opportunity to contribute to making a difference in the world.”
