Tu prototipo SaaS funciona. Tu arquitectura de producción, no.

Si eres un fundador que ya quemó $40K en un MVP de Bubble que no escala más allá de 500 usuarios, aprendiste la lección a las malas: los marketplaces necesitan código real.

What Actually Ships in a Production SaaS Platform — And What Doesn't

Your SaaS platform goes live the moment a second paying customer logs in and can't see the first customer's data. That's multi-tenant architecture — row-level security, isolated workspaces, real separation. Not just authentication. Not just separate accounts. True data isolation where your infrastructure serves hundreds of tenants without a single security boundary crossing. Marketplaces compound that. Now your platform connects buyers to sellers, handles escrow through Stripe Connect, calculates commissions across disputed transactions, and processes refunds when a buyer ghosts mid-order. One misconfigured payout flow destroys seller trust permanently. In marketplaces, sellers leaving is extinction. Under the hood: subscription billing wired through Stripe (failed charges, proration, disputes), dashboards that surface business-critical metrics, admin controls so you can actually run the operation, and your core differentiation logic — the matching algorithm, the commission structure, the access rules that make your platform worth building. That last part is the real engineering. We've built authentication and tenant isolation so many times it's reflex. But your specific business logic? That's what we architect together in week one.

Dónde fallan los proyectos

A traditional agency quoted you $300K and 9 months for your SaaS MVP Nine months. Think about what the competitive landscape looks like in nine months. By the time you're cutting a launch ribbon, someone else has already onboarded their first 200 paying users.
AI builders like Lovable or Bolt gave you a slick demo in 30 minutes -- and honestly, it looked pretty good But here's the thing: it falls apart the moment real data shows up. No multi-tenant isolation means customer A can literally see customer B's data. That's not a bug you patch. That's a rebuild.
Your co-founder shipped a prototype fast, which is great But it can't handle real payments, and Stripe isn't forgiving about edge cases. Failed charges, proration when someone upgrades mid-cycle, refund workflows, disputed transactions -- any one of these will break a billing system that wasn't architected to handle them.
You know you need Stripe Connect for marketplace payouts, but the documentation runs 500 pages and the edge cases are brutal One misconfigured payout flow and you've permanently damaged trust with your sellers. In a marketplace, sellers leaving is an extinction-level event.
Your MVP got you to early users -- good But it was built on Airtable, and you're already feeling the ceiling. There's a performance cliff coming, there's no real data isolation, and you're locked into a vendor that was never designed for what you're trying to build.
You've got paying users, which means you've validated something real But the codebase is held together with duct tape, and every new feature breaks two existing ones. The foundation was never properly architected -- and at some point, that debt comes due hard.

Cumplimiento

Multi-Tenant SaaS

Each customer gets their own isolated workspace using Supabase row-level security -- so there's no scenario where tenant data bleeds across accounts. Stripe subscriptions handle monthly and annual plans, feature flags control what each tier can access, and the whole thing provisions automatically the moment someone signs up. Pretty straightforward to use, genuinely complex to build correctly.

Two-Sided Marketplace

Buyers and sellers each get their own dashboards built around what they actually need. Stripe Connect handles escrow payments, commission calculations, and payout scheduling. Search runs through Algolia. And review systems -- with all the moderation headaches that come with them -- are built into the core workflow, not bolted on later.

Subscription Content Platform

Content gets gated behind subscription tiers, with usage-based billing, free trials, and upgrade flows that don't feel clunky. Video, articles, courses, downloads -- all of it is access-controlled per plan level. The real kicker is making those upgrade prompts convert without annoying your users.

Booking & Scheduling Platform

Multi-provider availability management, calendar integrations, automated reminders -- plus payment collection at booking and the cancellation and rescheduling workflows that every booking platform eventually needs. Because users will reschedule at 11pm on a Sunday, and the system has to handle it.

Admin & Analytics Dashboard

Platform-wide metrics, user management, content moderation, financial reporting, and the operational tools you need to actually run the business day-to-day. Real-time data, not yesterday's CSV exports sitting in someone's email.

API & Webhook Infrastructure

A public API lets other tools plug into your platform -- and that's when your product starts becoming infrastructure for someone else's workflow. Webhook system for real-time events, rate limiting, API key management, developer documentation. Suddenly you're not just a SaaS; you're a platform.

Nuestro proceso

01

Product Discovery

We define your core user journey, data model, and monetization strategy together. Then we identify the 20% of features that'll deliver 80% of the value for your MVP -- because scope creep is how timelines and budgets die. You walk away with a product spec and a fixed-price quote.
Week 1-2
02

Architecture & Design

Multi-tenant database schema, API design, Stripe integration plan, UI wireframes -- the full technical blueprint. You approve everything before a single line of production code gets written. No surprises three months in.
Week 3-4
03

Core Platform Build

Authentication, user onboarding, subscription billing, and the primary user dashboard -- deployed to staging with real Stripe test mode so you can actually run payment scenarios from day one. Not mock data. Real flows.
Week 5-8
04

Features & Polish

Core differentiating features, admin dashboard, email notifications, search and filtering. Each sprint ends with a demo of working software you can test against real scenarios -- not a slide deck about what we're planning to build.
Week 9-11
05

Launch + Growth

Production deployment, monitoring, analytics, team training, and 30 days of free support after launch. Then ongoing development at $5--15K per month to iterate based on what real users actually do -- which is almost never exactly what you planned.

Preguntas frecuentes

¿Cuánto cuesta construir un MVP de SaaS?

Un MVP de SaaS con calidad de producción cuesta entre $50,000 y $100,000 y toma entre 8 y 12 semanas. No es un prototipo desechable: es una base real con arquitectura multi-tenant, suscripciones con Stripe y la lógica principal que hace que tu plataforma valga la pena usar. La iteración post-MVP tiene un costo de $5,000 a $15,000 por mes. Y para el proyecto adecuado, la participación en equity está sobre la mesa.

¿Cuál es la diferencia entre un prototipo y un MVP de producción?

Un prototipo en Lovable o Bolt se ve muy bien en una demo, en serio. Pero no puede manejar usuarios reales, pagos reales ni aislamiento real de datos. Un MVP de producción tiene arquitectura multi-tenant adecuada donde los datos de cada cliente están verdaderamente aislados, una integración con Stripe que maneja suscripciones y casos borde de facturación sin romperse, e infraestructura que no requiere una reconstrucción completa en el momento en que empiezas a tener tracción. Eso es lo que estás pagando.

¿Pueden construir un marketplace de dos lados?

Sí. Hemos construido marketplaces con compradores y vendedores, pagos en custodia vía Stripe Connect, búsqueda y filtros, sistemas de reseñas y controles de administración. Gestión de catálogos multi-vendedor, cálculo de comisiones, programación de pagos, resolución de disputas: hemos trabajado todo eso. NAS gestiona 137K listings y sigue rindiendo.

¿Qué hay de la facturación por suscripción y los niveles de precios?

Integramos Stripe Billing para la gestión de suscripciones: planes mensuales y anuales, múltiples niveles de precios, facturación por uso, pruebas gratuitas, códigos de cupón, y flujos de actualización y degradación de plan. Construimos un sistema de suscripción de 4 niveles con más de 30 feature flags controlados por nivel de plan. Así que cuando dices "los usuarios premium deben ver X pero los básicos no", sabemos exactamente cómo arquitecturar eso.

¿Construyen apps móviles o solo plataformas web?

Construimos plataformas web-first que son completamente responsivas y funcionan muy bien en navegadores móviles. Para apps móviles nativas, podemos construir con React Native o conectar tu plataforma a un frontend móvil separado. Siendo honestos, la mayoría de los productos SaaS y marketplaces funcionan mejor como progressive web apps que como apps nativas, especialmente en la etapa de MVP. No agregues esa complejidad hasta que hayas validado el producto principal.

¿Qué pasa si mi idea necesita pivotar después del lanzamiento?

La arquitectura es modular a propósito. Podemos intercambiar funcionalidades, agregar nuevos roles de usuario, cambiar el modelo de facturación o pivotar la propuesta de valor principal sin reconstruir desde cero. La mayoría de nuestros clientes de SaaS iteran significativamente en los primeros 6 meses, porque los usuarios reales siempre tienen opiniones que tu especificación no anticipó. Está bien. Construimos pensando en eso.
