About Leafr

We exist because sustainability teams are too small for what's being asked of them.

Five years ago, a sustainability team could get by with a generalist. That era is over.

Today, a single sustainability lead is expected to navigate CSRD double materiality, set science-based targets, prepare CDP submissions, respond to investor ESG questionnaires, map Scope 3 emissions across a global supply chain, and answer the board's questions on biodiversity risk. Each is a distinct discipline with its own frameworks and evolving best practice. Each takes years to master. And the regulatory landscape is moving faster than any individual can keep pace with.

The people in these roles are being set up with an impossible brief. They know it. Their managers know it. But the alternatives have not been good enough.

Hiring full-time gets you one person's expertise, assuming you can find them in a market where qualified specialists are scarce. Consultancies have capacity but charge accordingly, and the person who pitched the work is rarely the person who delivers it. Leaning on your network is a gamble, and when the work is regulatory, reputational, or investor-facing, the cost of getting the wrong person is not a wasted fee. It is a missed deadline, a failed disclosure, or a board that loses confidence in the function.

The volume and complexity of sustainability regulation has outpaced what any single team can cover. The talent pool is too shallow to hire your way out of it. And the cost of getting it wrong has become material.

Leafr was built for this moment. A vetted network of senior sustainability specialists that companies can access project by project, bringing in precisely the right expertise at precisely the right time. So small sustainability teams can stop trying to be experts in everything and start delivering like a team of fifty

Our Founders

We've lived this problem from both sides

Leafr was founded by Nick and Gus after years of experiencing the same frustration from opposite ends. Nick spent years inside a Big Four consultancy before going independent. He saw how the traditional model worked from the inside and why it so often failed to deliver for clients. Gus had been on the other side, hiring consultants to solve supply chain and sustainability problems and struggling to find the quality of expertise he actually needed. Between them, they had lived both sides of the same broken market. The consultancy model was not built to match companies with the right specialist.

On-demand vetted specialist models were thriving in other disciplines, especially those facing harder regulation, scarce talent, and rising stakes. Legal, finance, technology, and cybersecurity had all moved towards flexible expert networks, and it was working. Companies got better outcomes, faster, and at a fraction of the cost of traditional alternatives.

Sustainability was facing every one of the same pressures, but had no equivalent infrastructure. It felt like the discipline was screaming out for it. So they built Leafr.
