Multi-tenant that scales without rewrites.
We build SaaS platforms from scratch — the kind of project where first-month decisions define the next five years. If that sounds familiar, this is the right page.
The decisions that separate a viable platform from one you'll throw away.
Multi-tenant isolation
Decide upfront whether you go shared schema, schema per tenant, or database per tenant. Each has serious trade-offs. The common path is to choose wrong and pay for it at 18 months.
Robust auth
Enterprise SSO, MFA, granular role and permission management. Auth0, Clerk, or WorkOS depending on the case. Sometimes self-hosted with Better Auth.
Billing
Stripe for most cases, Paddle when the client sells internationally and doesn't want to deal with per-country tax.
Audit log
Who did what, when, from where. Critical for enterprise and for SOC 2.
Metrics and dashboards
Your platform isn't just what clients see — it's also what you see about your clients. Stripe + PostHog + custom in-product dashboards.
Onboarding
The most underrated product moment. A well-built onboarding increases retention more than any flashy feature.
Public API
If your platform will live 5+ years, it'll need a public API. Designing it from the start is cheap. Rewriting it later is expensive.
What you'll likely wear.
Next.js 15 (App Router), Tailwind, shadcn/ui.
NestJS on Postgres with schema-level multi-tenancy (default), or row-level security with Postgres RLS policies when isolation can be logical.
Clerk for fast start, WorkOS when there are enterprise requirements (SSO, SCIM), Better Auth when zero lock-in is desired.
Stripe Connect or Stripe Billing depending on the model.
Cloudflare for frontend and edge functions, AWS for critical stateful services.
Starting a platform or rewriting one?
Both cases are ours. The first call focuses on understanding where you are — a new MVP and a 3-year platform in technical debt are very different problems.
