01
We ship, not pitch.
Decks are for people who can't build. We give you working software in days and let it argue for itself.
The studio
Small studio. Real work.
Brighton, UK. Founded by Sam Erpik. We make Luna, an AI receptionist on WhatsApp for appointment businesses, and you can phone us up if something goes wrong.
The story
Founder-built
Purple Luna is a small AI studio in Brighton. Founded by Sam Erpik, who builds AI products for a living. We make Luna, an AI receptionist on WhatsApp.
We started because too many small businesses were being sold AI by people who'd never shipped a working product. We build AI that actually works, and we sweat the details most agencies skip.
Luna runs today for a barber in Brighton, an aesthetics clinic in London and a dental clinic. She's £99 a month + VAT, with 14 days free once she's live.
How we work
Three rules we don't break.
02
Plain English, always.
We don't write the buzzwords and we don't pad emails. We write the way you'd talk in your shop. Short sentences. Real answers.
03
Your data is yours.
We don't lock you in. If you linked your own WhatsApp number, it stays in your own Meta account. Ask within 30 days of leaving and we'll send you your chats and booking data.
