How and why I built QR Jolt as a solo founder

I got tired of seeing small businesses tape a QR code to their window, with no idea whether anyone ever scanned it.

No data. No flexibility. If the link changed, the whole thing was dead, and they were reprinting.

So I built QR Jolt to fix that.

Here is what it does and who it is for.

The problem

Most QR codes are static. Print it once, and it is frozen forever. No scan data, no way to update the link, no way to know if your marketing is actually working.

For a realtor hanging yard signs every weekend, that is a real problem. For a restaurant updating its menu every month, the same thing.

What QR Jolt does

Dynamic QR codes you can update anytime without reprinting. Real-time scan analytics showing who scanned, when, where, and what device. A/B testing to split traffic and see what converts. Artistic QR codes that turn high-contrast photos into something people actually want to scan. A link-in-bio landing page. And Shorti by QR Jolt for short links.

Who it is built for

Realtors are our primary focus. Yard signs, listing flyers, open house codes, business cards. They do physical marketing every single day, and most of them have no idea what is working.

But honestly, any small business doing print marketing gets it immediately. Restaurants, gyms, event companies, you name it.

The tech

Built solo on Next.js. Supabase for the backend, auth, and database. Stripe for payments because it just works. Gemini is powering the customer chatbot.

Still early. Still building. But it is live, it is real, and I am here all day if you have questions or feedback.

Would love to know what you think.
