The Opportunity

Problem

Solo SaaS freelancers suffer cash flow shortages from clients delaying payments, preventing them from covering monthly expenses or investing in tools and marketing.

Solution

Post your delayed invoice to the marketplace; get matched with a freelancer who pays you instantly for a small discount (2-5%). They claim your invoice from your client or swap back. Community-powered cash flow without banks.

Target Audience

Solo SaaS freelancers billing clients on delayed payment terms

Differentiator

P2P network effect—freelancers pay each other early, building trust scores over time.
