Software-as-a-Service is the default delivery model for modern B2B tools, but standing up a multi-tenant platform correctly from day one is harder than it looks. Get the architecture right early to avoid a costly re-platform.
Building in SaaS without the right technical guidance means navigating serious pitfalls with high stakes.

Building a billing system that handles trials, upgrades, downgrades, and proration cleanly
Designing role-based access control that scales across organisations and workspaces
Achieving the observability needed to diagnose issues per-tenant without mixing data
