About Payflows
Software that helps large companies manage and automate their payment workflows
At Payflows, we build software that helps large companies manage and automate their payment workflows: invoices, approvals, payments, and controls. We're building toward an agent-driven finance platform, where intelligent agents handle the repetitive tasks, and users stay in control. We started in 2022 and work with major companies across France, the UK, and the US while choosing to keep our team small and human-sized.
Mission
We believe the future of finance operations is not faster clicking: it's no clicking at all. Software should do the operational work, and humans should focus on reviewing, approving, and making the decisions that matter.
