MVP through production SaaS — auth, billing, AI native from day one.

Multi-tenant SaaS products built end-to-end. Authentication, billing, role-based access, an AI-native architecture, observability, and a deployment pipeline shipped on the first day, not bolted on after launch. Stack: Next.js, FastAPI, Postgres with pgvector, Redis, Stripe, Cloudflare.

What you get on day one

Most SaaS builds add multi-tenancy, billing, and AI as v2 retrofits. That is the most expensive way to build SaaS. We put them in the day-one foundation so v2 is product features, not architectural rework.
Architecture

Multi-tenant from line one

Row-level tenant isolation in Postgres. Every query scoped by tenant ID. No bolt-on multi-tenancy six months in. Hosted on Cloudflare or your cloud — you choose.

Auth

Real authentication

Email + password, magic link, OAuth (Google, GitHub, Apple), SSO when you need it. Passkeys ready. Built on Stytch or your own NextAuth deployment.

Billing

Stripe billing wired in

Plans, seats, usage-based metering, trials, dunning, customer portal. The whole loop, not just a checkout button.

AI native

AI built into the product

RAG against tenant data, chat surfaces, intelligent search, embeddings indexed per tenant. Not a chat bolt-on — AI as a first-class feature.

Observability

You can see what is happening

Structured logs, traces, metrics, error tracking. Sentry + Logtail + Posthog or your own stack. No flying blind in production.

Deploy

CI/CD and infra-as-code

GitHub Actions deploys on every push to main. Database migrations versioned. Infrastructure described in Terraform or Pulumi. The deploy is not a manual step.
