About Aeterno

Built for decisions that need evidence

Governed AI agents for asset-heavy organisations — turning connected energy assets into auditable, evidence-backed outcomes.

Who we are

Aeterno builds governed AI agents for asset-heavy organisations. We help OEMs and estate operators turn connected energy assets into evidence-backed decisions — with an auditable trail from assessment through operations. Founded in 2020 and based in Bath, England, we combine deep energy modelling expertise with production-grade software to deliver outcomes you can prove.

Where we come from

Years of real-world energy consultancy gave us a deep understanding of how homes and buildings really behave — and thousands of modelled buildings to learn from.

Milestone

Scale & Expand

Expanded to commercial estates (UBMA). Growing partner ecosystem. Continuous platform evolution.

From consultancy insights to platform innovation

Those lessons shaped everything we build today: agents designed for real-world performance, governed from the start, and grounded in evidence.

What we've proven

Our platform has been in production for multiple years, managing thousands of assets for OEM partners across the home energy sector. Active partnerships drive daily workflows — from standards-aligned design and quotation through to commissioning and performance verification.

We provide detailed evidence packs and references in confidence as part of due diligence.

How we work with customers

We start with a contained proof of value on live data, then expand coverage and automation together.

Once value is proven, we extend along the asset lifecycle — increasing automation only where evidence supports it.
