“Can a lightweight, ZZP-first Dutch bookkeeping brand grow into a financial OS for Dutch freelancers under Visma, with an embedded Swan payment account at its center?”
Rompslomp was founded in 2015 as a ZZP-focused Dutch bookkeeping SaaS, built around a 'Getting Things Done' philosophy (invoices, shoebox receipts, VAT returns, one click). It was acquired by Visma in 2022 and remains a standalone brand within Visma Group. Since the acquisition, its stack has been Visma-ified (open banking via Visma, shared infra) and it has moved into embedded finance via a Swan-powered business payment account launched as 'Rompslomp Betaalrekening'.
Rompslomp discloses Swan as its banking provider, according to the Embedded Finance Index 2026.
Rompslomp does not disclose a bank charter of its own; its banking services are provided through Swan.
Rompslomp connects to bank accounts through Visma.
The Embedded Finance Index 2026 maps 2 layers in Rompslomp's stack: Banking / BaaS (Swan); Open banking (Visma).
Rompslomp was founded by Jaap van der Meer and Niels Koning and is founded in 2015, headquartered in Den Haag, Netherlands.
