Making the second-hand case with real numbers
Impact measurement for Europe's largest second-hand marketplace, when we were still working at Rebel.
1 projects, in order
Each one grew out of the last. This is what a long engagement actually looks like.
Impact model
Built the model behind the avoided-emissions claim from the ground up.
Methodology setHow it actually went
Written by the person who did the work, not by marketing.
Vinted's sustainability story was intuitive but unquantified, and increasingly risky under tightening scrutiny.
We built the impact model behind the avoided-emissions claim and stress-tested every assumption. We built the model in such a way, that the impact could be determined on the single transaction level.
Maxine and Nina conducted this project when they were still working as consultants at Rebel
Other long-running relationships
Maxine and Nina started working for OLX when they were still consultants at Rebel. Six years later, OLX Group is still with us. Client Ana: "I'll keep you on retainer forever."
Bugaboo acquired Joolz, and inherited Maxine along the way. She's now helping them prepare for B Corp under the new 2025 standards, and migrating LCA data from her Joolz days to measure the product footprint across 40+ strollers and accessories.
De Bonte Koe has always had sustainability in their minds, but B Corp certification kept getting pushed aside. When their pistachio bar went viral and the team hit full capacity, we stepped in to get them over the finish line.
