Polisense.AI is tackling one of the most critical barriers in energy transition: the planning bottleneck that prevents projects from ever being implemented!

Today:
– Nearly half of energy projects never get executed
– 760 million people still lack access to electricity
Polisense.AI is an co-pilot for government energy planning — helping cities move from fragmented data and slow processes to fast and informed decisions. In short: they accelerate the energy transition by eliminating the planning bottleneck!

With Polisense, governments can:
• Ask complex planning questions in natural language
• Prioritize energy sites based on impact and feasibility
• Integrate fragmented datasets into one unified system
• Generate regulatory-compliant reports in minutes instead of months

The result?
⚡ Up to 85% faster decision-making
⚡ Up to 80% reduction in project delays

Already live with municipalities across the world,
founders Bruno Galdos and José Pastor are showing how AI can unlock ex*****on in climate action.
