Most sustainability leaders carry the agenda alone. The weight of it is real, and most of the time there's nobody nearby who gets it. Leafr Leaders is where that changes.
Get honest answers to hard questions, from people navigating exactly the same thing.










Cross sector and industry specific collaboration
Everything you need to deliver sustainability with confidence, in one community.

Your confidential peer group of six leaders, meeting regularly throughout the year. A fully confidential, and structured format to have the conversations that can't happen anywhere else.

One-to-one guidance from leaders who have already navigated what you're navigating. Focused, personal, and entirely on your terms.

Regular sessions with peers in your sector, thinking through the challenges that are specific to your industry.

Ask questions, share what's working, and connect with peers across industries, frameworks, and challenges. The kind of forum where you actually get a useful answer.

Direct access to people who are writing the rulebooks to seek clarification and get answers. e.g. SBTi, ISO, B Corp, Green Claims, Ecovadis.

Monthly socials and an annual conference to put faces to names. Drinks, surfing, climbing, boules. The informal stuff that makes the formal stuff work better.

Regular training and cohort based courses on topics that are pertinent to your role and development: AI in sustainability, frameworks, communication, the business case.

Tools & services recommended by peers that have actually used them.

Exclusive savings on the conferences & software, and services you already use. Membership pays for itself before you've attended a single event.
Built to work around you. No big time commitment — just the right touch points, when you need them

Meet ups that quickly move from pleasantries to value add conversations

The best reviewed conferences in sustainability. Just ask any of the attendees.

Events that you can actually get excited about, designed for honest conversation and meaningful exchange.
We all agree to have honest and open conversations in the knowledge that confidentially is of paramount importance.
The best communities run on generosity. Show up for others without keeping score and the whole room moves faster.
The best conversations start with admitting what's hard. We're commercially minded, down to earth, and don't take ourselves too seriously.
Nick and Gus had worked with hundreds of sustainability leaders at the UK's most well-known companies, and they kept hearing the same thing: "I'm in a small, siloed team with no support network". We started out running simple group dinners to connect those leaders, and the energy was incredible. Attendees asked for more. Leafr Leaders was born out of those dinners, and we've stuck true to the approach: intimate connections between like-minded leaders in sustainability. We've seen what separates the leaders who move fast from those who stall. Almost always, it comes down to who they have around them. Nick Valenzia and Gus Bartholomew Co-Founders of Leafr Leaders
We believe the best communities act like the ultimate personal advisory board. Big enough to have diverse perspectives and small enough to be fully trusted.
Tell us about yourself and what you'll bring to the community.
We'll talk through fit and where you'd add to, and gain from, the community.
If it's a match, you're welcomed in. We're selective, because the quality of the room is the product.
You're matched into your confidential peer group of six, and introduced to the wider community.
Join an invite-only community of sustainability leaders who help each other move faster.
