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
