Turning daily work into measurable climate impact.

In many organisations, sustainability stays stuck in reports and one-off initiatives. Ambition exists, but without a concrete path for employees to act, daily behaviour barely changes. Sustainers offers a Change-as-a-Service platform that translates everyday work into measurable CO₂ and business impact, with practical tools, sector-specific content and dashboards that make sustainable action visible, actionable and manageable.

How it works

Sustainers offers a Change-as-a-Service platform that translates everyday work into measurable CO₂ and business impact. With practical tools, sector-specific content and dashboards, it makes sustainable action visible, actionable and manageable.

Market size
110,000 companies

Sustainers turns sustainability from an administrative obligation into a structural part of how a business runs, directly linking shop-floor behaviour to boardroom results, so it becomes a demonstrable value driver instead of a cost.

Huddles collaboration

Huddles has worked closely with Sustainers since 2025: on the cap table, in the room.

Why we backed them

In many organisations, sustainability stays stuck in reports and one-off initiatives. Ambition exists, but without a concrete path for employees to act, daily behaviour barely changes, and without measurable results, it's felt as an obligation rather than real value.

How Huddles engaged

We co-build from the inside: backing Sustainers through the pre-seed fund, with hands-on studio support on strategy, hiring and go-to-market.

Where they stand

First organisations onboarded, with the platform validated in pilot and partner projects across sectors under high sustainability pressure. Focus now: deepening the product and scaling by sector.

Going from black box to a steerable service is not a step you take alone. Huddles thinks with you as a co-builder, not as a supervisor. That's exactly the difference that makes impact scalable.
