For nonprofits
Serious about your mission
Real money is at stake, so trust comes first. The whimsy is in the experience — never in how we handle your fundraiser.
Raise more per prize
Round-by-round play keeps every bidder contributing, not just the top bid. Each round a bidder stays is a real gift to your cause — paid win or lose — so engagement turns directly into dollars.
Trust comes first
Clear invoices, transparent per-round fees, and a verifiable winner for every prize. Real money, handled carefully.
Easy to run
Set up prizes in minutes and run the whole event from a browser. No special equipment, no training day.
Engaging for bidders
It feels like a game, not a form, so your supporters stay involved while the room energy climbs.
Built around your event
Donors, prize details, redemption instructions, and results all live in one place.
Results, automatically
When the auction ends, winners and invoices are summarized for you and emailed to participants.
Organizer tools
Built for the team running the fundraiser
CapyBidder is not a bidder landing page with an admin panel bolted on. The organizer workflow is the core product: set up the event, run the room, and close out results.
Prepare prizes
Capture donor names, fair market value, photos, restrictions, redemption details, and the fee per round.
Start with control
Open prizes automatically, manually, or after a delay so the auction rhythm matches your event program.
Monitor live state
See which prizes are live, whose turn it is, how many bidders remain, and what each participant has contributed.
Close the loop
When prizes finish, review winners, invoice totals, donor credits, and redemption instructions from the results screen.
What you need to run one
Almost nothing. If you can fill out a form, you can run a CapyBidder auction.
- A few prizes and their donors
- A computer with a browser to run the event
- Bidders with phones to play along
