Every building. Every half hour.
Send us an energy bill and see your own data. Free to start.
The problem
A monthly bill can’t show which building is wasting energy.
Half-hourly data shows which buildings run well and where to look deeper. Optimise then tells you why.
What you see
Every building on one page, worst first.
Energy, cost and carbon for your own buildings, plus live carbon from the grid. Not a sales demo.
