CartaSin
Digital restaurant menus with built-in allergen information, multi-tenant so it could serve several businesses from one platform. Built in my low-code era and eventually sold.

- Problem
- Restaurants needed to show their menus with allergen information clearly, across many venues, without rebuilding it each time.
- Role
- Founder and builder. Sold.
- Stack
- Low-code, multi-tenant.
The story
CartaSin digitized restaurant menus with allergen information built in, in a multi-tenant format to serve several businesses from a single platform. I built it in my low-code era and ended up selling it.
Why it matters
It's part of the period where I learned to build a multi-tenant product and actually sell it, not just build it. The distinction between "making a website" and "running a product with paying customers" was forged here.
Let's talk
I work where product, technology and business meet, and I like talking to people building real things there. Whether it is to compare notes, a problem worth solving, a project, or a role, my inbox is open.
