Warum wir tiptilldone für die WM26 neu bauen.

Vier Events, 119 Spieler, 76% Activation. Was wir 2014-2016 gelernt haben — und warum die nächste Version anders ausschauen muss.

Four events, one lesson

We built tiptilldone the first time in 2014, for the Brazil World Cup. Four tournaments, 119 tippers, 76% returned for the second event. "Push notification" was still a prediction back then.

What changed since

Polymarket exists. AI models that judge football better than 90% of tippers. Telegram bots are grown up. WhatsApp is the comms layer.

What tiptilldone 2026 does differently

  • AI Picks with reasoning for every one of the 104 matches
  • Polymarket live data right next to your tip input
  • Telegram bot so the round lives in your group chat
  • Soulbound NFT trophies — earned, not tradeable
  • Build-in-public on GitHub

When does it kick off

June 11, 2026, opener in Mexico City. Until then we build in front of you — every commit, every decision documented.
