Jack's backstory


Jack was initially conceived as a payment solution for companies that preferred to pay by purchase order (PO) but had suppliers who wanted to be paid by card. The co-founders, Nicolai and Tosin, met at an accelerator in London. However, transactional accounting teams considered this a nice-to-have feature rather than a necessity. When the co-founders inquired about the most tedious and time-consuming tasks in accounting, there was a unanimous agreement: retrieving invoices from clients, manually reconciling half of the invoice, and chasing clients to pay their bills. This revelation led to a pivot in Jack's focus. Now, Jack is designed to be readily available wherever your clients are already working and communicating – be it email, WhatsApp, Slack, or Teams. This integration makes it incredibly simple for clients to snap a picture of a receipt or invoice and send it in, streamlining the invoice submission and reconciliation process.
