About SparkTower
SparkTower is a place to start a business and to practice running one. Write down an idea and SparkTower's AI, Nova, turns it into a plan; run the business as a live market simulation before you risk real money; and build it in public with people who want to see it work.
Business simulations anyone can run
Any kind of business — a café, a software startup, a clinic, an online store — becomes a market simulation with real customers, prices and rivals. Play it alone, as a team of five, or as a whole class.
Built for classrooms and companies
Teachers run seasons for a class with a join code and a host console; companies run private training seasons for their staff. The host controls the clock, the events and the players, and exports the results.
A marketplace of simulations
People who build a good simulation can sell it on the SparkTower marketplace to other classes, clubs and founders, and keep most of every sale.
Nova, the AI behind it
Nova writes simulations from a description of a business, plans the next steps for a project, and can play a company's plan for you to show what a careful founder would do.
In over thirty languages
The whole site can be read in more than thirty languages, among them Spanish, Chinese, Hindi, Arabic, French, Swahili, Twi and Hausa, and in Easy English for anyone who reads English slowly.
In ChatGPT too
The SparkTower app in ChatGPT finds simulations, explains their markets and plays them with your own numbers, with no account needed.
Who runs it
SparkTower is made by SparkTower LLC, based in Wisconsin, United States, at sparktower.app.
