Why we are rebuilding tiptilldone for WC26.

Four events, 119 players, 76% activation. What we learned in 2014-2016 — and why the next version has to look different.

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.
