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.

Wo Projekte scheitern

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.

Compliance

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.

Was wir bauen

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

Unser Prozess

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.

Häufige Fragen

Was bedeutet es, von Lovable oder Bolt.new zu "graduieren"?

AI-Code-Generatoren wie Lovable, Bolt.new und v0 sind beeindruckend beim schnellen Erstellen funktionsfähiger Prototypen. Aber sie überspringen konsequent die Produktions-Essentials: Row-Level Security, korrekte Auth-Flows, Payment-Webhook-Handling, eine Architektur, die nicht bei 1.000 Nutzern zusammenbricht. Graduation bedeutet: Wir nehmen deinen Prototype, extrahieren die UX-Muster, die tatsächlich funktionieren, und bauen auf einem Stack auf — Next.js, Supabase, Clerk, Stripe — der in sechs Monaten nicht komplett neu geschrieben werden muss.

Warum Next.js und Supabase statt eines Custom Backend?

Next.js gibt dir Server-rendered React mit Edge Functions, ISR und API Routes in einem Framework. Supabase stellt Postgres mit Real-Time-Subscriptions, Row-Level Security und Edge Functions zur Verfügung, was bedeutet, dass du keinen separaten Backend-Service brauchst. Zusammen sind sie der schnellste Weg zu einer produktiven SaaS, die jeder Senior React Developer pflegen kann. Du besitzt den Code und die Datenbank. Kein Lock-in.

Kann ich Paddle statt Stripe für Zahlungen verwenden?

Ja. Paddle fungiert als Merchant of Record und kümmert sich um EU-VAT, Sales Tax und Invoicing — du musst dich nicht selbst für VAT in mehreren Ländern registrieren. Wir empfehlen generell Paddle für B2B SaaS, die in Europa verkauft, und Stripe für US-first oder Usage-based Billing Modelle. Beide integrieren sich mit Clerk für Entitlement Gating. Wir geben dir eine klare Empfehlung während der Audit-Phase basierend darauf, wo deine Kunden tatsächlich sind.

Was passiert nach der 30-tägigen Post-Launch-Unterstützung?

Du erhältst den vollständigen Source Code, Deployment-Konfiguration und Dokumentation. Die Codebase läuft auf Standard Next.js und Supabase — jeder kompetente React Developer kann sie pflegen. Wenn du nach dem Launch weitere Entwicklung möchtest, bieten wir Retainer-Pakete an. Aber das Ziel ist ein sauberer Handoff zu deinem Team oder deinem nächsten Hire, nicht dass du von uns abhängig bleibst.

Wie funktioniert die Festpreis-Preisgestaltung bei Scope-Änderungen?

Wir definieren den Scope in der Week-1-Audit: spezifische Features, Data Models, Integrationen. Die Festgebühr deckt diesen Scope ab. Wenn du mid-build etwas hinzufügen möchtest, scopen und preisen wir es separat, bevor irgendwelche Arbeiten beginnen. Keine Überraschungsrechnungen, kein Stundenhonorar, bei dem "es hat länger gedauert als erwartet" plötzlich dein Problem wird. Du kennst die Kosten von Anfang an.

Arbeitet ihr mit non-technical Foundern zusammen?

Die meisten unserer MVP-Clients sind non-technical oder semi-technical Founder. Das ist genau der Punkt — du konzentrierst dich auf Validierung, Kunden und Fundraising, während wir die Architektur-Entscheidungen treffen. Wir kommunizieren in klarer Sprache mit wöchentlichen Demos, nicht Jira-Tickets. Du verstehst genau, was gebaut wird und warum, ohne Pull Requests reviewen zu müssen.
