Crowdz is an invoice exchange that allows companies to auction and sell their unpaid invoices to investors in order to accelerate cash flow. It operates an auction and exchange platform that connects companies, banks, hedge funds, and other investors. The invoice market is estimated to be worth $9 trillion, but companies currently have to wait 30-120 days to receive payment, straining their cash flow. Crowdz aims to reduce this time by allowing invoices to be sold for earlier payment.
