Nmbrs BV

Nmbrs BV builds the HR and payroll stack that Dutch small businesses and accounting firms actually run on. Founded in 2004 and headquartered in Amsterdam, the company sells a single cloud platform spanning four product organizations - Nmbrs Payroll, Nmbrs Accounting, Nmbrs Invoicing, and Nmbrs Reporting - plus HR automation features like expense declaration processing and digital signing, and compliance management tooling. It serves thousands of entrepreneurs and accounting firms. The data at stake is the unglamorous, high-consequence kind: payroll runs, financial records, and the personal and identity information that moves through digital signing and HR workflows.

Being cloud-based and multi-tenant across payroll and accounting domains means the platform sits at the intersection of financial systems and regulated personal data, with compliance management itself treated as product surface rather than back-office paperwork. Nmbrs operates as part of Visma Group, one of Europe's largest software conglomerates, and runs engineering teams across three offices - Amsterdam, Lisbon, and Stockholm - in the Netherlands, Portugal, and Sweden.

The operating model is unusual enough to matter to anyone evaluating how the security work actually gets done: a permanent four-day workweek as standard for all employees, a flat hierarchy with no traditional managers, and personal coaches in the manager's place. The stated premise is full productivity inside four days, with an emphasis on employee development. Four product organizations share one unified brand and one platform, so cross-cutting concerns - identity, signing, payroll processing, reporting - don't sit neatly inside a single team's walls.
