Annwn helps find the data, chase the relevant people, reconcile it, draft the disclosure, and flag where judgement is needed. You just review and refine.
Helping sustainability teams work faster, better, and reach further.

The strategic work you want to do keeps getting relegated and you can't reach the whole organisation.
You deserve better tools. So we're building them.

Annwn helps find the data, chase the relevant people, reconcile it, draft the disclosure, and flag where judgement is needed. You just review and refine.

Your context (e.g. data requests, board notes, plans and performance reports) is combined with our unique corpus of sustainability insight to produce connections and work you couldn't manually.

Sustainability propositions translated into the language of CXOs, boards, and investors. Risk quantified, cost estimated, investment justified.

Patterns across datasets that point to cost reduction, risk exposure, or untapped commercial value. Annwn uncovers the real next win.
Annwn is where sustainability teams think, talk,
and tackle the work together.
We'll start by helping you with work you'll know well, completing it quicker and better. But you'll quickly see your data working for you in ways it never has before.
Doing the jobs you have to do faster and better
Helping with everyday work in sustainability
Performance related sustainability initiatives.

By combining your data with our model, architecture, agents and curated corpus of sustainability knowledge, you can make the connections that allow you to work better and faster, and uncover new value or risk.
Every output connects back to its evidence; the why and how behind each decision, the sources, and the confidence you should place in them. And if anyone leaves, their knowledge and insight stays.
