What team size do I need to build a Laravel SaaS?

An MVP can be built by a small team of 2 to 3 engineers plus a part time project manager and QA. A production mid-market SaaS typically needs 4 to 6 engineers, a project manager, a QA engineer, and design support. An enterprise platform may need 8 to 12 people including backend, frontend, DevOps, security, QA, and project management. The right size depends on timeline pressure and scope. Throwing more people at a project does not linearly speed it up, so we scope team size to the work rather than maximising headcount and cost.
