How a Used-Car Dealer Built an AI SaaS in 5 Days — With No Code

🚗 Introduction: When Manual Tasks Stall Growth

Leo, a seasoned used-car entrepreneur, had a vision. After 14 years of sourcing, importing, and selling vehicles, he was buried under browser tabs, spreadsheets, and tedious admin work. Every car listing he reviewed had to be copied, cleaned, and emailed manually.

He didn’t know how to code — but he knew something had to change. So he explored no-code tools.

After hitting roadblocks with Adalo and Softr (slow performance, poor backend support, no paywall integration), Leo nearly gave up.

Then he found Momen.

🔧 From Hustle to Builder: What Was the Problem?

In the used & repairable car business, most vehicle info comes from sites like Copart, IAAI, or AutoTrader. But these sites are inconsistent — many don’t have APIs. Critical details are buried in cluttered layouts.

Leo’s vision: build a custom system to scrape vehicle data, clean it with AI, and manage it all in a dashboard.

No-code tools weren’t up to the task. Adalo lagged with real data. Softr required complex Airtable setups and had no scraping support.

He needed something better. A real system. A SaaS.

⚙️ The Build: An AI SaaS in Under a Week

Leo used Momen to build a full SaaS, in 3 parts:

1. Chrome Extension (Built in Cursor)

  • Handles user auth and permission checks via Momen APIs.

  • Scrapes vehicle info and location data from listing pages.

  • Sends raw text to Momen backend for processing.

2. Momen Backend

  • Actionflow kicks off when new data arrives.

  • AI Agent structures data (VIN, damage status, pricing).

  • Stores clean records in a structured, queryable database.

3. Momen Frontend (Management Dashboard)

  • Staff can view/edit vehicle listings.

  • Set prices and trigger automated emails.

  • Built-in Stripe paywall for subscription-based access.

All of this was built in less than 5 days for under $100.

💡 Why Momen Made the Difference

  • AI Where It Matters: Instead of spamming ChatGPT prompts, Leo’s agent cleaned the messiest data with structured outputs.

  • Bridge to the Web: No APIs? No problem. The extension + Momen turned any site into a structured data source.

  • No Glue Code: No Airtable juggling, no Zapier madness. One platform for backend, frontend, AI, and auth.

⏱️ Time + 💸 Money Saved

Traditional dev: ~$20K+ in engineers & infra.

With Momen: <$100 in tools + one week.

Leo saved 95% in startup cost and now processes car data in minutes, not hours.

✅ Final Thoughts

Momen didn’t just help Leo automate — it helped him build a sellable SaaS product, without writing a line of code.

This is what’s possible when non-technical founders combine domain expertise with the right no-code + AI platform.
