Would a dedicated database per company change how much you trust a task manager?

Launching QuickTaskManager on Product Hunt soon. Unlike most task managers (Asana, Monday, ClickUp...), which put every customer in one shared database, each company here gets its own physically separate database and its own link (yourcompany.sepirox.com).

Curious: does real data isolation actually matter to you when picking a work tool, or is it just an engineering detail? Ever had a bad experience with a shared multi-tenant system?

Happy to answer anything about how it's built.
