AI SaaS & MVP Development
Amex Technology takes SaaS and AI product ideas from prototype to a launch-ready MVP: sign-up and login, Stripe subscriptions, multi-tenant data protected by row-level security, AI features with cost controls, and analytics.
Already built a first version in Lovable, Bolt or Replit? We review it, fix the security and data problems AI builders commonly leave behind, and get it ready for real users and real traffic.
What we build
Launch-ready MVP
The one core workflow your users pay for, with authentication, onboarding, email and Stripe billing.
Multi-tenant security
Each customer's data separated by row-level security policies in the database, not just in the front end.
AI features with limits
AI generation, summaries or agents inside the product, with per-plan usage limits and cost tracking.
Prototype-to-production hardening
Code export, security review, fixed RLS policies, environment variables, error monitoring and proper hosting for apps started in AI builders.
Who it's for
- Founders who need a working MVP to show customers or investors
- Non-technical founders with an AI-built prototype that's hitting its limits
- Businesses turning an internal tool into a product they can sell
- Products adding AI features without runaway API bills
How we work
- Step 1
Define the core workflow
We cut the idea down to what version one must do to be worth paying for.
- Step 2
Architecture
Data model, tenancy and billing designed up front, because they're expensive to change later.
- Step 3
Build and demo weekly
Short cycles with a preview link, so you can test with early users as we go.
- Step 4
Launch and iterate
Production hosting, monitoring and analytics, then improvements based on real usage.
Our development team is in India and our founder, Abhi Patel, is based in the Los Angeles area, so US clients get working hours that overlap with theirs. Working with Los Angeles businesses.

Questions
How much does a SaaS MVP cost?
A SaaS platform typically starts from $5,000, and the final figure depends on the number of user roles, integrations and AI features. After a discovery call we send a fixed, itemised quote for version one.
Can you finish an app I started in Lovable, Bolt or Replit?
Yes. We export the code to your own GitHub, review the database and security rules, and fix or finish it. In most cases that's cheaper than starting over, and we'll tell you honestly when it isn't. Our free App Checker gives a quick first look.
What stack do you use for SaaS?
Usually Next.js and TypeScript on Vercel, Supabase for the database, auth and storage, Stripe for billing, and OpenAI or Claude for AI features. We adapt to an existing stack when you already have one.
How do you keep AI costs under control?
We set usage limits per plan, cache repeat requests, choose the cheapest model that does the job well, and track AI spend per customer so pricing covers it.
