DRY RUN
90 days in 90 seconds

Run your business before you spend a cent.

Dry Run builds a crowd of synthetic customers around your idea and lets you live 90 days of it. Rain, rivals, viral posts, empty Tuesdays. Then it tells you what to test for real.

        The grand mission

        Nobody risks their savings blind again.

        Most small businesses that fail were never tested. Their owners learned the numbers with their rent money. Dry Run wants every first-time founder, from a juice cart in Kisumu to a nail studio in Warsaw, to see the crash before it happens.

        Year 1
        A simulator for 40 common small-business types in 30 cities. Every real 7-day test that users log makes the synthetic crowds sharper.
        Year 2
        Calibrated by thousands of real test weeks. Microlenders and savings groups accept a Dry Run report as part of a loan application.
        Year 3
        The world's open dataset of how small businesses actually behave, street by street. Run any idea anywhere and see the honest odds in 90 seconds.

        The founder counter

        If 1 in 4 ideas that fail on Dry Run never get funded with savings, and the average first business loses the equivalent of 5 months' income, every 10,000 runs protects roughly 2,500 households from that loss.
