Business Development Lead

Sustainability professionals are working on some of the most consequential challenges of our time — helping businesses understand their impact, meet their obligations, and make meaningful changes for climate, nature, and communities.

At Annwn, we're building tools to help them do that work better. We use the most current thinking in AI to build reliable, purposeful technology for sustainability professionals — not generic tools repurposed for the job, but systems designed around how this work actually gets done.

The AI landscape moves fast, and knowing what to use, how to trust it, and how to get real value from it beyond a simple chatbot is genuinely hard. We're doing that thinking so sustainability professionals don't have to — giving them intelligent, structured tooling that augments their expertise, keeps them in control, and helps them deliver better outcomes for their clients and organisations.

We're human-centric by design — the professional's judgement, expertise, and relationships remain at the centre of everything. Technology serves the work, not the other way around.

We believe the best outcomes for business and the world come from empowering the people already doing the hard work — not replacing them.

We're hiring a Business Development Lead: a senior, commercially minded leader who will build the relationships, partnerships and revenue that take Annwn early customers to an established presence in corporate sustainability.

You'll be selling into large enterprises, where sustainability sits across several functions and buying decisions involve sustainability leaders, finance, procurement, IT and risk. That demands patience, credibility and a real understanding of the pressures sustainability teams face. You won't be selling software for its own sake. You'll be showing senior professionals how better tooling strengthens their work and their standing inside the business.

You'll also build our partnerships with consultancies, assurance providers, data platforms and industry bodies, which we expect to be as important to our growth as direct sales.

Working closely with the founders, in a tight start-up team, you'll shape our go-to-market strategy, proposition and pricing, and lay the foundations of the commercial function as it grows.

• Build and own a pipeline of enterprise customers, from first conversation through to signed contract
• Lead multi-stakeholder sales cycles, bringing in the wider team where needed
• Develop and manage partnerships across consulting, assurance, data and the wider sustainability ecosystem
• Shape our go-to-market approach, positioning and commercial model with the founders
• Represent Annwn at events, in industry forums and across the sustainability community
• Bring market insight back to product, so that what we build reflects what customers will buy
• Put in place the processes, tools and, in time, the team that a scaling commercial function needs

• Significant senior experience of business development in the sustainability sector at a CSO/ C-suite level
• An established network among corporate sustainability leaders
• A background in leadership in sustainability consulting or in-house sustainability with enough substantive knowledge of the landscape to be credible with both a Head of Sustainability and their peers
• The judgement to build long-term relationships rather than chase short-term numbers
• Strong appetite for early-stage work: comfortable building from scratch, with ambiguity and working at pace
• A genuine commitment to the purpose

• Experience as an early commercial hire in a start-up or scale-up
• A track record of building partnerships
• Experience selling AI or data products, including handling procurement, InfoSec and AI governance scrutiny

• Build Annwn's commercial function from the ground up, with real ownership over strategy
• Work directly with experienced founders who have built and sold a sustainability business
• Be part of a mission-driven team building something genuinely new
• Equity to reflect the importance of the role
