Production from day one

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.

Dónde fallan los proyectos

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.

Cumplimiento

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.

Qué construimos

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

Nuestro proceso

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.

Preguntas frecuentes

¿Qué significa 'graduarse' de Lovable o Bolt.new?

Los generadores de código AI como Lovable, Bolt.new y v0 son genuinamente impresionantes produciendo prototipos funcionales rápido. Pero consistentemente saltan los essentials de producción: row-level security, flujos de autenticación adecuados, manejo de webhooks de pago, arquitectura que no colapsa con 1,000 usuarios. Graduarse significa que tomamos tu prototipo, extraemos los patrones UX que realmente funcionan, y reconstruimos en un stack — Next.js, Supabase, Clerk, Stripe — que no necesitará una reescritura completa en seis meses.

¿Por qué Next.js y Supabase en lugar de un backend personalizado?

Next.js te da React renderizado en servidor con funciones edge, ISR y rutas API en un framework. Supabase proporciona Postgres con suscripciones en tiempo real, row-level security y funciones edge, lo que significa que no necesitas un servicio backend separado. Juntos, son el camino más rápido a un SaaS de producción que cualquier desarrollador React senior puede mantener. Eres dueño del código y la base de datos. Sin lock-in.

¿Puedo usar Paddle en lugar de Stripe para pagos?

Sí. Paddle actúa como merchant of record, manejando IVA de la UE, impuestos sobre ventas e invoicing — así no tienes que registrarte para IVA en múltiples países tú mismo. Generalmente recomendamos Paddle para SaaS B2B vendiendo a Europa y Stripe para modelos US-first o basados en uso. Ambos se integran con Clerk para gating de entitlements. Te daremos una recomendación clara durante la fase de auditoría basada en dónde tus clientes realmente están.

¿Qué ocurre después de que termina el soporte de 30 días post-lanzamiento?

Obtienes código fuente completo, configuración de deployment y documentación. El codebase corre en Next.js y Supabase estándar — cualquier desarrollador React competente puede mantenerlo. Si quieres desarrollo continuo después del lanzamiento, ofrecemos paquetes de retainer. Pero el objetivo es un handoff limpio a tu equipo o tu próxima contratación, no mantenerte dependiente de nosotros.

¿Cómo funciona el pricing de precio fijo con cambios de scope?

Definimos scope en la auditoría de la Semana 1: features específicas, modelos de datos, integraciones. El precio fijo cubre ese scope. Si quieres agregar algo durante la construcción, lo scopeamos y lo preciamos por separado antes de cualquier trabajo. Sin facturas sorpresa, sin billing por horas donde "tomó más tiempo de lo esperado" de repente se convierte en tu problema. Conoces el costo por adelantado.

¿Trabajan con founders no técnicos?

La mayoría de nuestros clientes de MVP son founders no técnicos o semi-técnicos. Ese es genuinamente el punto — te enfocas en validación, clientes y fundraising mientras nosotros manejamos las decisiones de arquitectura. Nos comunicamos en inglés simple con demos semanales, no tickets Jira. Entenderás exactamente qué se está construyendo y por qué, sin necesidad de revisar pull requests.
