📸 Why this exists

A spare Wimbledon
ticket. An app.

Jan had a spare ticket. John was a friend of her nephew. By the time Djokovic lifted the trophy they'd discovered a shared obsession — and a 25-year age gap that turned out to be entirely irrelevant when it came to reading a draw.

The bet over lunch followed. The spreadsheet followed that. And then, eventually, this.

2018
A spare ticket to Wimbledon
Jan had a spare. John took it. By the time Djokovic lifted the trophy they'd discovered a shared obsession — and a 25-year age gap that was entirely irrelevant when it came to reading a draw.

2019
The lunch bet
Australian Open. Both convinced they'd read the draw better. Stakes: whoever picked fewer correct quarterfinalists bought lunch. Jan won. John paid. The bet became an annual ritual.
📊
2020–2023
The spreadsheet years
Four years. Multiple Grand Slams. One increasingly elaborate Google Sheet — wildcards, multipliers, tiebreakers, penalty clauses for late picks. It worked. It was also deeply unglamorous.
💻
2024
The app begins
John started building. First: a Flask app to replace the spreadsheet. Then leagues, then teams, then an AI news pipeline, then AI players named Martina and Roger who pick every tournament and publish their reasoning.
