Built for how clubs already talk

Your club's AI agent, right inside WhatsApp.

No app for members to install. Your branded AI agent works across the WhatsApp your members already use: it broadcasts open courts, matches and tournaments to your community, then takes each booking and payment into a private 1:1 chat, one tap away. Money and personal details never go public, and managers run ops and reports from the same private chat.

  • No app to install: it works in the WhatsApp groups your members already use
  • Books, cancels and takes payment in a private 1:1 chat: money and personal details never go public
  • Broadcasts open courts, matches and tournaments to your community, and pulls players in with one tap
  • Works while you sleep: reminders, waitlist fill, no-show nudges and win-backs fire on their own
  • Yours, in every language: branded as your club for padel, pickleball and tennis
A WhatsApp demo: the club's AI assistant broadcasts a freed-up court to the Matches channel with a tap-to-book link, the chat moves to a private one-to-one with the assistant, the member confirms, and the assistant locks the booking with a secure payment button.
