Test your million-dollar idea.
Learn how a business really starts, then build yours one step at a time. SparkTower teaches young students and new entrepreneurs how to enter a market and grow a business.
Turn your idea into a business with AI guidance, a plan that adapts to you, a startup simulator to test it in, and people to build alongside.
Write down the idea and Nova, SparkTower's AI, turns it into a path: the next step, what to make, who to talk to. Run the business in a startup simulator against rivals before you spend real money. Post your progress, find a cofounder, and follow what other founders are building.
