Place a bid

Put your product in the stack

The top product in Harness is what free compute plugs. Your position follows your bid.

Tracking query strings are stripped.
The first bid in a category is $100. Move into #1 for $100. Existing sponsors pay only the difference when they raise their bid.

A completed Stripe payment is what claims the rank. Payments are not refundable. Each bid also stitches Jensen a new leather jacket.
