Company · Rectangle
The team behind LeCloud.
Rectangle has spent years building and operating the most regulated workloads in Europe. LeCloud is the productization of that practice — a sovereign, AI-ready PaaS layer above SecNumCloud IaaS.
Why we built LeCloud
Sovereign teams deserve a real platform. Not a stack of VMs and a slide deck.
We delivered regulated e-invoicing on Outscale SecNumCloud infrastructure for a French banking e-invoicing operator and migrated 100+ TB of probative archives off AWS for a leading European digital trust provider. Both projects ended the same way: the missing piece was a productized sovereign platform layer. So we built it.
What LeCloud is not
- Not a consulting engagement — LeCloud is a product
- Not a hyperscaler skin — sovereign by construction
- Not playful — built for regulators, auditors and CISOs
