What You Actually Get When Your Prototype Graduates to Production

Your buyer signs up. Clerk authenticates them, Supabase enforces row-level permissions, Stripe captures their card, PostHog logs the activation event — and nothing breaks. A SaaS MVP launch takes your Lovable, Bolt.new, v0, or Claude Code output and rebuilds it on a named stack: Next.js for the frontend, Supabase for multi-tenant data, Clerk for auth, Stripe for billing, PostHog for analytics. Every integration is wired correctly from day one. No placeholder logic. No 'we'll add payments later' technical debt. You ship a real business — authentication that handles team workspaces, subscription billing with upgrade flows, feature flags for controlled rollouts, and deployment pipelines that don't require your intervention. Your prototype proved demand. This delivers the architecture that demand requires.

Onde os projetos falham

Your Lovable or Bolt prototype looks great in a screen recording Then real users show up and it falls apart. Early adopters churn before you've got enough traction to show investors anything meaningful.

AI-generated code skips the hard stuff — no auth, no row-level security, no payment integration Those gaps aren't just technical annoyances. They're trust killers, and they tend to surface at the worst possible moment.

Traditional agencies will quote you 6 months and $150K for a v1 Meanwhile, the market window you're trying to hit doesn't care about their timeline.

You've hired a few freelancers, each with their own preferred stack and patterns A year later, you're staring at a full rewrite. This is more common than anyone admits.

You launch with no analytics, no behavioral tracking, nothing No data on where users drop off, what features they actually use, or whether anyone's coming back.

Payment integration always gets pushed to the end Then it breaks. You can't charge customers, you can't validate willingness to pay, and closing your round gets a lot harder.

Conformidade

Clerk Authentication

Multi-tenant auth with SSO, MFA, and role-based access from Sprint Zero. We don't roll our own auth — Clerk handles session management, user metadata, and organization switching out of the box, so we're not reinventing something that's already solved.

Supabase Row-Level Security

Every database query is enforced by Postgres RLS policies. Users only see their own data. Your API surface stays protected even if client-side code gets compromised.

Stripe & Paddle Payments

Stripe handles core subscriptions and usage-based billing. If you're selling into Europe, Paddle's available for EU VAT compliance and merchant-of-record simplicity. Both wire into your auth layer for gated access.

PostHog Behavioral Analytics

Event tracking, session replay, feature flags, and A/B testing from day one. You'll know exactly where users drop off and which features are actually driving retention — not guessing after the fact.

Production Architecture

Next.js App Router with server components, edge functions, and ISR. Built for Vercel deployment with proper caching, error boundaries, and monitoring wired in from week one.

SEO & Performance Baseline

Server-rendered pages, structured data, and Core Web Vitals optimization aren't an afterthought — they're baked into the build. Your SaaS ranks and loads fast from the first deploy.

O que construímos

Graduate AI-generated prototypes into named-stack architecture that survives contact with production traffic

Your early adopters sign up, invite teammates, and stay — because authentication, permissions, and data isolation actually work

Rebuild Lovable, Bolt.new, v0, or Claude Code outputs on Next.js, Supabase, Clerk, Stripe, and PostHog

You collect real payment data from day one instead of pushing billing integration to 'phase two' and losing validation momentum

Implement multi-tenant data models with Supabase RLS so team permissions work correctly from launch

Your stack uses production-proven tools that any senior engineer can maintain — no bespoke frameworks only one person understands

Wire Stripe subscription billing and Clerk entitlements into a clean upgrade pipeline that charges customers reliably

You ship feature rollouts to 10% of users, measure impact, and expand — without coordinating deploys or breaking existing workflows

Deploy feature flag infrastructure with PostHog for percentage rollouts and dark launches without redeploying

Your behavioral analytics capture where users drop off, which features drive retention, and whether anyone's coming back for a second session

Configure Vercel preview environments, error tracking, and uptime monitoring before handoff

You hand investors a deployed product with real usage data, not a screen recording of a demo that breaks under load

Nosso processo

Audit & Architecture

We review your existing prototype, validate your data model, map your auth and billing requirements, and produce a technical spec with the exact stack configuration. No ambiguity. You know what you're getting before we write a line of code.

Week 1

Sprint Zero — Foundation

Supabase schema with RLS policies, Clerk integration, Stripe or Paddle billing skeleton, PostHog instrumentation, and a CI/CD pipeline. The unglamorous infrastructure work that makes everything else possible.

Weeks 2-3

Core Feature Sprints

One-week sprints building your core product workflows. Daily async updates, weekly demos. Each sprint ships a deployable increment to your preview environment — you're never waiting weeks to see progress.

Weeks 4-7

Launch Hardening

Performance optimization, security audit, error handling, edge cases, load testing. We're targeting 95+ Lighthouse scores and sub-200ms API responses. This is the week where we stop adding and start hardening.

Weeks 8-9

Ship & Support

Production deploy to Vercel, DNS cutover, monitoring verification, and 30 days of post-launch support. You get full source code, documentation, and a clean handoff to your team.

Perguntas frequentes

O que significa 'graduar' do Lovable ou Bolt.new?

Geradores de código IA como Lovable, Bolt.new e v0 são genuinamente impressionantes na produção de protótipos funcionais rápidos. Mas consistentemente pulam os essenciais de produção: segurança em nível de linha, fluxos de autenticação adequados, manipulação de webhooks de pagamento, arquitetura que não colapsa com 1.000 usuários. Graduação significa que pegamos seu protótipo, extraímos os padrões de UX que realmente funcionam, e reconstruímos em uma stack — Next.js, Supabase, Clerk, Stripe — que não precisará de uma reescrita completa em seis meses.

Por que Next.js e Supabase em vez de um backend customizado?

Next.js oferece React renderizado no servidor com funções edge, ISR e rotas de API em um único framework. Supabase fornece Postgres com subscrições em tempo real, segurança em nível de linha e funções edge, o que significa que você não precisa de um serviço de backend separado. Juntos, são o caminho mais rápido para um SaaS de produção que qualquer desenvolvedor React sênior consegue manter. Você possui o código e o banco de dados. Sem lock-in.

Posso usar Paddle em vez de Stripe para pagamentos?

Sim. Paddle atua como merchant of record, tratando VAT da UE, impostos sobre vendas e faturamento — então você não precisa se registrar para VAT em vários países. Geralmente recomendamos Paddle para SaaS B2B vendendo para a Europa e Stripe para modelos com foco nos EUA ou faturamento baseado em uso. Ambos se integram com Clerk para bloqueio de direitos. Daremos uma recomendação clara durante a fase de auditoria com base em onde seus clientes realmente estão.

O que acontece após o suporte de 30 dias após o lançamento?

Você recebe o código-fonte completo, configuração de implantação e documentação. O código roda em Next.js e Supabase padrão — qualquer desenvolvedor React competente consegue mantê-lo. Se você quiser desenvolvimento contínuo após o lançamento, oferecemos pacotes de retenção. Mas o objetivo é uma transição limpa para seu time ou sua próxima contratação, não mantê-lo dependente de nós.

Como funciona o preço de taxa fixa com mudanças de escopo?

Definimos o escopo na auditoria da Semana 1: recursos específicos, modelos de dados, integrações. A taxa fixa cobre esse escopo. Se você quiser adicionar algo durante a construção, definimos o escopo e o preço separadamente antes de qualquer trabalho começar. Sem faturas surpresa, sem faturamento por hora onde "demorou mais do que o esperado" de repente se torna seu problema. Você sabe o custo antecipadamente.

Você trabalha com fundadores não técnicos?

A maioria de nossos clientes de MVP são fundadores não técnicos ou semi-técnicos. Esse é genuinamente o ponto — você se concentra em validação, clientes e arrecadação de fundos enquanto lidamos com as decisões de arquitetura. Nos comunicamos em português claro com demos semanais, não tickets Jira. Você entenderá exatamente o que está sendo construído e por quê, sem precisar revisar pull requests.
