Financial literacy kids actually want to play.
Stock Battle: the stock-card game — built together with my 8-year-old daughter and AI, live on the App Store & Google Play.

Problem
Financial literacy barely appears at school — and where it does, it's dry. Kids have little playful access to stock markets, companies and money decisions.
The idea came from an analog stock-card game and playing it with my daughter. From there — completely inexperienced, with the help of AI — we built Stock Battle: bull versus bear, real companies as cards.
Hypotheses
- Kids learn finance best by playing, in the familiar card-game format.
- Two audiences — kids and parents — need different goals within the same game.
- Real metrics on the cards make abstract terms tangible.
- Themed stacks by region & sector keep motivation and convey breadth.
- Collecting and reward mechanics (golden cards) carry extra knowledge.
Target metrics
- Rounds played and return rate
- Concepts understood (market cap, dividend, margin, valuation)
- Shared parent-child play time
- Downloads & ratings on the App Store / Google Play
KPIs
- 24 themed stacks of 32 cards each — e.g. S&P 500 Heavyweights, Asia Large Caps, German Engineering (DAX), Pharma Big Caps
- Playable metrics per card: market cap, dividend yield, margin, daily performance
- Round duel: compare a metric, bull versus bear — win or lose
- One golden knowledge card per round (milestones, innovations and flops)
Outcome
Kids get a feel for companies, markets and decisions in minutes — and parents play along.
A project that shows how far you can get with AI even without prior experience: from first prototype to live in the app stores.
