How to build a SaaS product from scratch is a product company problem dressed as engineering. Sequence discovery, tenancy, billing and distribution or you will rebuild expensive foundations later.
Phase 0 — problem and ICP
- Painful workflow you can charge for
- Buyer vs user identified
- Willingness-to-pay signal (even if qualitative)
- Competitive wedge written in one paragraph
Phase 1 — thin multi-tenant MVP
Auth, tenant isolation, core workflow, basic admin. Defer marketplace and AI until the core loop works. Our SaaS development builds follow this cut. Deep dive: SaaS MVP guide.
Phase 2 — monetisation and ops
- Plans, trials and invoices
- Support tooling for your team
- Observability and backups
- Onboarding that does not require a CSM for every account
Build vs partner decisions
Compare in-house, a SaaS partner, or a dedicated team. Match the model to fundraising and hiring reality. Review portfolio for B2B patterns.
