Simplify's Take
What believers are saying

What critics are saying
- Public-contract dependence exposes revenues to municipal budget delays and procurement cycles.
- OpenProcurements shows only narrow recent wins, including Valenciennes and Saint-Nazaire bids.
- Energy-transition consulting faces commoditization if larger integrators bundle design, works, and financing.
What makes ALTEREA unique
- ALTEREA won Nord GTB engineering work worth €567,861 in April 2026.

- Nine agencies across France and 400-plus employees support national public-sector delivery.
