At Flux, we’re rethinking what payroll infrastructure should look like for the global economy. In markets like Mexico, Brazil, and Germany, small businesses and global payroll companies still rely on spreadsheets, consultants, and manual processes to pay their teams. These markets lack the modern payroll APIs and tax automation that companies in the U.S. take for granted. Flux is changing that: we’re building foundational infrastructure—secure APIs for payroll calculations, tax filings, and compliance updates—so that payroll & HR software companies, banks, and accountants can launch local payroll products in weeks, not years.
If you’re running a payroll or HR tech company, Flux enables you to expand into new markets without building country-specific infrastructure from scratch. Our APIs help you automate tax calculations, file payments with local authorities, and stay on top of changing regulations. With Flux, you’ll reduce manual effort, avoid costly compliance mistakes, and deliver a better payroll experience to your customers and teams worldwide.
We're assembling a team of builders, fintech engineers, and operations leaders to tackle this global problem. Our founders have scaled payroll products at Deel, Rippling, and Sphere, and we’re applying that hard-won experience to solve payroll’s global infrastructure gap. If you are interested in partnering with us, we’d love to talk. Join us in building the future of global payroll together.
