el que cuida tu negocio
The AI that runs your business while you sleep.
Don Sereno builds and runs your local business — bilingual, on the rails Puerto Rico runs on. You rest; the watchman doesn't.
Every barrio had a sereno — the night watchman who walked the street, called the hour, and kept the shops safe while everyone slept.
Don Sereno is that, as software.
- Builds your site.
- Takes the orders.
- Answers in two languages.
- Runs the menu, the hours, the payments.
- Watches the shop 24/7 — so you can rest.
