Cumulative. Community. Commerce.
The price starts at a dollar so almost anyone can take part, and it climbs a little with each sale. Your community becomes the major backer, and you earn predictably as word spreads. It works for online courses, fundraisers, bundle promotions, livestream tickets, and crowdfunding projects.
Built for independent artists and creators, and anyone with a project and an audience.
If you have something to sell and people who care about it, Bumpsale turns that community into momentum. Artists, course creators, nonprofits, bootstrappers, and small businesses use it to fund their work without gatekeepers taking a cut of everything.

Every purchase raises the price by one cent. That's the whole idea.
“…I'll start something at $1 and then I'll make the increments one dollar. So the first person buys it for $1, the second person for $2, the third for $3 and so on and so forth. And doing that I have made thousands and thousands of dollars at a time.”
“Bumpsale is a genuine game changer, hands down best engagement we've seen on an offer. We did a month's worth of revenue in 20 hours using Bumpsale! It just works for activating an audience and inciting action.”
“Bumpsale is a perfect storm for urgency pricing with digital products: I made $40,860 using it this year!”
