Our platform transforms reductions into certified Scope 3 results that supply chain participants can use to prove progress, reward farmers, and build trusted climate claims. ## "Keep the planet liveable for future generations." "Agriculture and food supply chains hold one of the biggest opportunities for meaningful climate action. Fertilizer use is a major driver of emissions. By addressing it, we create impact where it counts: in the systems that feed the world." CEO, [Sijbrand Tieleman](https://www.linkedin.com/in/sijbrand/) Founded in Amsterdam, Proba was born out of a shared belief that waiting for governments to act on climate change isn’t an option. Our team of international experts ( small in size, bold in ambition) bring together diverse backgrounds in digital innovation, sustainability and collaboration.  As a start-up, we move fast and adapt quickly. Our focus is on delivering results, simplifying complex processes, and helping our partners succeed at every step. Decarbonization is a shared challenge. That’s why we connect partners across the supply chains, from farmer cooperatives to global brands, to share costs, create value and drive real change. We want to make sure your impact is certified for direct and indirect emission reductions in the agri-food supply chain [Read more about our mission](https://proba.earth/why-proba?hsLang=en) ![Proba graphics (11)](https://proba.earth/hubfs/Proba%20graphics%20(11).png "Proba graphics (11)") ## The wonderful people working at Proba ![Untitled design - 2026-06-22T143131.257](https://proba.earth/hubfs/Untitled%20design%20-%202026-06-22T143131.257.png) ### Sijbrand Tieleman CEO & Co-Founder [Follow us on Facebook](https://www.linkedin.com/in/sijbrand/) ![Proba team (3)](https://proba.earth/hubfs/Proba%20team%20(3).png) ### Rutger Beens Co-Founder [Follow us on Facebook](https://www.linkedin.com/in/rbeens/) ![Proba team (2)](https://proba.earth/hubfs/Proba%20team%20(2).png) ### Frank De Zwart Product Manager [Follow us on LinkedIn](https://www.linkedin.com/in/frdezwart/) ![Proba team](https://proba.earth/hubfs/Proba%20team.png) ### Erna Maciulis Marketing Lead [Follow us on LinkedIn](https://www.linkedin.com/in/erna-maciulis/) ![Proba team (1)](https://proba.earth/hubfs/Proba%20team%20(1).png) ### Nikos Vellis Scientific Lead [Follow us on Facebook](https://www.linkedin.com/in/nikos-vellis-823769278/) ![Proba team (6)](https://proba.earth/hubfs/Proba%20team%20(6).png) ### Konstantinos Dimitriou Technical Lead [Follow us on Facebook](https://www.linkedin.com/in/konstantinos-dimitriou-074955164/) ![Proba team (8)](https://proba.earth/hubfs/Proba%20team%20(8).png) ### Vladimir Davidovic R&D Lead [Follow us on Facebook](https://www.linkedin.com/in/vladimir-davidovic-99a802267/) ![Proba team (9)](https://proba.earth/hubfs/Proba%20team%20(9).png) ### Wajdi Almir Technical Lead [Follow us on Facebook](https://www.linkedin.com/in/wajdialmir/) ![Proba team (11)](https://proba.earth/hubfs/Proba%20team%20(11).png) ### Ewan Sheldon Software Engineer [Follow us on Facebook](https://www.linkedin.com/in/ewan-sheldon-215842131/) ![Proba team (10)](https://proba.earth/hubfs/Proba%20team%20(10).png) ### Damanpreet Kaur Research Consultant [Follow us on Facebook](https://www.linkedin.com/in/damanpreetkaurbhamra/) ![Proba team (7)](https://proba.earth/hubfs/Proba%20team%20(7).png) ### Camilla Bovati Sustainability Consultant [Follow us on Facebook](https://www.linkedin.com/in/camillabovati/) [![Subheading 2nd 3rd (35)](https://proba.earth/hubfs/Subheading%202nd%203rd%20(35).png "Subheading 2nd 3rd (35)")](https://www.linkedin.com/in/sijbrand/) [![Subheading 2nd 3rd (34)](https://proba.earth/hubfs/Subheading%202nd%203rd%20(34).png "Subheading 2nd 3rd (34)")](https://www.linkedin.com/in/rbeens/) [![Subheading 2nd 3rd (36)](https://proba.earth/hubfs/Subheading%202nd%203rd%20(36).png "Subheading 2nd 3rd (36)")](https://www.linkedin.com/in/frdezwart/) [![Subheading 2nd 3rd (3)](https://proba.earth/hubfs/Subheading%202nd%203rd%20(3).png "Subheading 2nd 3rd (3)")](https://www.linkedin.com/in/erna-maciulis/) [![Subheading 2nd 3rd (24)-1](https://proba.earth/hubfs/Subheading%202nd%203rd%20(24)-1.png "Subheading 2nd 3rd (24)-1")](https://www.linkedin.com/in/konstantinos-dimitriou-074955164/) [![Subheading 2nd 3rd (37)](https://proba.earth/hubfs/Subheading%202nd%203rd%20(37).png "Subheading 2nd 3rd (37)")](https://www.linkedin.com/in/nikos-vellis-823769278/) [![Subheading 2nd 3rd (40)](https://proba.earth/hubfs/Subheading%202nd%203rd%20(40).png "Subheading 2nd 3rd (40)")](https://www.linkedin.com/in/vladimir-davidovic-99a802267/) [![Wajdi Almir](https://proba.earth/hubfs/Wajdi%20Almir.png "Wajdi Almir")](https://www.linkedin.com/in/wajdialmir/) [![Proba graphics (13)](https://proba.earth/hs-fs/hubfs/Proba%20graphics%20(13).png?width=486&height=858&name=Proba%20graphics%20(13).png "Proba graphics (13)")](https://www.linkedin.com/in/ewan-sheldon-215842131/) [![Proba graphics (12)](https://proba.earth/hs-fs/hubfs/Proba%20graphics%20(12).png?width=486&height=858&name=Proba%20graphics%20(12).png "Proba graphics (12)")](https://www.linkedin.com/in/damanpreetkaurbhamra/) ## Proba Standard Advisory Board ![Proba team (13)](https://proba.earth/hubfs/Proba%20team%20(13).png) ### Lena Euwans Chair [Follow us on Instagram](https://www.linkedin.com/in/lena-euwens/) ![Proba team (12)](https://proba.earth/hubfs/Proba%20team%20(12).png) ### Danielle de Man Secretary [Follow us on LinkedIn](https://www.linkedin.com/in/danielledeman/) [![Subheading 2nd 3rd (33)](https://proba.earth/hubfs/Subheading%202nd%203rd%20(33).png "Subheading 2nd 3rd (33)")](https://www.linkedin.com/in/lena-euwens/) [![Subheading 2nd 3rd (32)](https://proba.earth/hubfs/Subheading%202nd%203rd%20(32).png "Subheading 2nd 3rd (32)")](https://www.linkedin.com/in/danielledeman/) ![Subheading (5)](https://proba.earth/hs-fs/hubfs/Subheading%20(5).png?width=317&name=Subheading%20(5).png "Subheading (5)") [Laan van Kronenburg 14, 1183 AS Amstelveen](https://maps.app.goo.gl/aKif8v1k5m9h2zA37)   Food companies are asking for certified Scope 3 reductions.
