B-Boosters, powered by The Overview Effect.

In 2026 we joined The Overview Effect, a collective of sustainability professionals helping organisations turn commitments into measurable progress. For you, that means deeper expertise, greater capacity, and the same dedicated B Corp team you came for. B Corp remains at the core of everything we do. The partnership adds access to broader ESG expertise, from climate strategy to human rights and circularity, whenever your business needs it.
