A startup simulator built from your own business
Run the company before you start it. SparkTower turns your idea into a market of its own — the customers, what they pay, and the rivals already in it — and lets you run it month by month.
Your market, not a template
Nova, SparkTower's AI, writes the simulation from your project: who buys, what they pay, what it costs to serve them and who you are up against. Or play one of the ready-made markets.
Every decision a founder makes
Price, marketing, product, hiring, capacity, borrowing and raising money. Each period resolves against rivals and the economy, and the forecast shows what your plan does before you file it.
Alone or as a team
Run every desk yourself, or seat a team of five — chief executive, marketing, product, operations and finance — and argue it out.
Play other founders' simulations
The simulations marketplace has markets other founders built from their own businesses, with what companies typically end up with shown before you play.
