Job DescriptionAbout Us
We are are building an agentic AI & intelligence platform for sustainability action and decision-making.
Organisations today are drowning in fragmented environmental data - carbon, biodiversity, water, policy, supply chains & more - but still struggle to answer the most important questions:
What should we do next?
What s the impact if we do?
What s the return on action - financially and environmentally?
Our startup exists to close that gap.
We are building a workflow and decision making layer on top of sustainability data: AI agents that ingest messy real-world inputs, reason over them, run scenarios, recommend actions, and learn from outcomes over time. All while building up a knowledge and context graph to build the single best view of how the organisation works today.
This is from a team who has worked in the sustainability space for years and have successfully exited a prior business to one of the largest businesses in the world. We re now taking that learning and building the AI- version of sustainability consulting.

Ingest and structure unstructured sustainability data
