SaaS Development & AI Fixes

Turn a tool into a business. We take AI-generated prototypes and engineer the complex infrastructure required to sell software subscriptions: secure payments, team management, and scalable data isolation.

The “Prototype” vs. “SaaS” Gap

AI is excellent at writing code that solves a specific problem for one user. It is terrible at building the infrastructure to sell that solution to thousands of users.

A true SaaS platform requires:

  • Multi-Tenancy: Ensuring User A never sees User B’s data.
  • Recurring Billing: Handling upgrades, downgrades, and failed payments automatically.
  • Team Workspaces: Allowing users to invite colleagues and manage permissions.
  • Onboarding Flows: Automated emails and tours to reduce churn.

If you have a cool tool but no way to charge for it securely, we bridge that gap.

Where AI Code Breaks in SaaS

1. The “Data Leak” Risk

The Issue: AI often writes database queries like SELECT * FROM projects. The Reality: In a SaaS, this exposes everyone’s data to everyone. Our Fix: We implement “Row Level Security” (RLS) and strict tenant isolation middleware. Every query is scoped to the specific user’s Organization ID.

2. The Billing Nightmare

The Issue: AI can generate a Stripe button, but it fails to handle webhooks (e.g., what happens when a credit card expires?). The Reality: Users get locked out or get free access forever because the state isn’t synced. Our Fix: We build robust webhook listeners that sync Stripe status with your database in real-time. We handle trials, pro-rating, and cancellations gracefully.

3. Hardcoded Limits

The Issue: AI code often isn’t built to scale. It might store files locally or hardcode configuration. The Reality: Your app crashes the moment a second user logs in. Our Fix: We implement scalable cloud storage (AWS S3/R2), environment variables, and stateless architecture perfect for auto-scaling.

Our SaaS Architecture Stack

We use modern, type-safe stacks designed for speed and reliability.

The Core

  • Framework: Next.js (React) or Remix
  • Language: TypeScript (for bug-free code)
  • Styling: Tailwind CSS

The Infrastructure

  • Auth: Clerk, NextAuth, or Supabase Auth (Social login + MFA)
  • Database: PostgreSQL with Prisma or Drizzle ORM
  • Payments: Stripe or Lemon Squeezy
  • Email: Resend or SendGrid (Transactional emails)

Development Packages

1. The SaaS Starter (MVP)

Timeline: 3-5 Weeks Best For: Validating a product idea quickly.

We take your core feature and wrap it in a sellable package:

  • User Authentication (Google/Email)
  • Basic Subscription Plans (Monthly/Yearly)
  • User Dashboard
  • Landing Page Integration
  • Result: A product you can actually charge for.

2. The Scale-Up (Pro)

Timeline: 6-10 Weeks Best For: Growing businesses needing robust features.

Everything in MVP, plus:

  • Team/Organization Management (Invite members)
  • Role-Based Access Control (Admin vs. Member)
  • Usage-Based Billing (e.g., “Charge per seat” or “per GB”)
  • Admin Admin Panel (Manage your users)
  • Advanced Analytics & Reporting

3. The AI Code Rescue

Timeline: 2-3 Weeks Best For: Fixing a broken prototype.

You have a codebase from ChatGPT/Claude that works locally but fails in production.

  • Code refactoring & cleanup
  • Security patching
  • Database optimization
  • Deployment setup (Vercel/Railway/AWS)

Success Stories

The “Free Tool” to “Paid Product”

Challenge: A client built a great AI writing tool using ChatGPT code, but it was just a local script. Solution: We wrapped the script in a Next.js app, added Clerk for auth, and integrated Stripe. Result: Launched in 4 weeks, reached $2k MRR in the first month.

The Multi-Tenant Fix

Challenge: A CRM prototype showed every client’s data to every logged-in user due to bad AI logic. Solution: We rewrote the database schema to support Organizations and implemented Row Level Security. Result: 100% data isolation, achieved SOC2 compliance readiness.

FAQ

Do you take equity? No. We are a development agency. You own 100% of the code and the business.

Can you use a boilerplate? Yes! If you want to save money, we can start with popular boilerplates (like ShipFast or others) to jumpstart development, then customize the core features.

What happens if I stop paying? Nothing breaks. We hand over the keys. Since we build on standard platforms (Stripe, Vercel, Supabase), your app keeps running as long as you pay those providers directly.
