Financial products carry a lower tolerance for downtime, ambiguity, or data errors than almost any other category of software.

Typical companies
Mid-size to large enterprises · Regulated industries (finance, healthcare, logistics) · Companies with decade-old core systems

Multi-tenant architecture that isolates customer data without a rewrite
Typical companies
Early-revenue SaaS startups · Teams outgrowing a single-tenant MVP · Product teams adding a paid tier to an existing tool
