Products I co-founded that businesses run on every day, and platforms I built for clients.
The operating system for padel and tennis clubs.
Bookings, school, tournaments, matchmaking, invoicing, WhatsApp/email, analytics and shop in one panel. Pilot club Padelko (10 courts, Bizkaia) went from three people and a spreadsheet to one system – website included.
From brief to finished treatment, in one place.
AI workspace for commercial directors, treatment designers and producers. Save references with a Chrome extension, get AI first drafts from the brief, edit together in real time and share live links with agency and client.
Bookkeeping on autopilot for hospitality and retail.
AI reads invoices from a photo, email or Telegram, reconciles the bank account, flags supplier price rises and bundles the monthly package for the accountant. In use at Padelko and Vene's Burguer.
