About Promti
Promti is made and run by one person, Eric Rodríguez Rosselló, in Barcelona, Spain. His legal name, tax number and address are on the legal page.
What it sells
Four immersive website kits, Product, Forest, App and Studio, each a finished one-page site for one kind of business. Every kit costs €500, paid once, and the buyer owns the files: they download their site and host it wherever they like, with no monthly fee to Promti.
Every kit comes with step-by-step guides and a 30-minute call with Eric.
Before September 2026
Until 25 September 2026, Promti sold “AI build kits” of templates and prompts at €49; the site has since been rebuilt around immersive website kits, and those earlier kits and their prices no longer exist.
