Overview

Intersoftware is a Dutch software company that develops financial advisory and intermediary software for the insurance and financial services markets. Founded in 1995, the company has built a dominant position in the Dutch financial advisory ecosystem with its flagship Adviesbox platform, which serves over 3,000 users across independent advisors, advisory chains, banks, and insurance companies. Acquired by DIAS Group in December 2022 from ING Bank, Intersoftware is transitioning to cloud-native architecture while maintaining market leadership.

The company operates on an API-first platform model that enables third parties to build branded advisory applications. Its core technology delivers product information feeds, mortgage and tax calculation engines, customer data management, and document storage capabilities. Intersoftware's success is evidenced by independent market research showing Adviesbox has won the best advisory software award seven times, and by its use as the foundation for platforms deployed by other fintech companies such as Knab and Fiew.

As a PE-backed technology company with a 30-year track record, established product-market fit, and expanding cloud capabilities, Intersoftware represents the infrastructure layer of the Dutch financial advisory market.
