Our mission
Banking belongs in business software
Many software companies already serve small businesses incredibly well : helping them send invoices, run payroll, manage inventory, and more. They’re on a mission to become the central hub for managing every aspect of business life.
But when it comes to financial workflows, there’s still a gap. Too many critical tasks like managing cash flow, tracking payments, or reconciling accounts happen outside the software, across spreadsheets, email threads, banking portals.
It’s a missed opportunity. Business software shouldn’t just record financial activity — it should run it.
