Why we built Rulebooks?
We love structure. And we believe transparency shouldn’t be a struggle. In every company, entity charts, compliance files, and ownership data tend to live in scattered spreadsheets, outdated slides, or email threads. We saw how much time that costs — and how easy it is for mistakes to creep in. So we built Rulebooks to bring clarity, structure, and confidence to legal operations.
A single platform where teams can see the full picture, trust their data, and focus on what really matters: good governance and smart decisions.
Because when structure is clear, transparency follows naturally.
Rulebooks is a Dutch legal tech startup founded by Harm Bavinck and Michiel Mosterd. After selling the enterprise legal management platform Effacts to Wolters Kluwer, we joined forces again to build a new Legal Ops platform.
We found a few external investors willing to provide initial capital to accelerate the development of the Rulebooks platform. By the end of the year, the first release of the platform was put into use by a number of customers.
Based on the feedback from the first customers, we are working with a team of software developers to further develop the platform. In the Fall of 2025, we launched the Rulebooks Org Chart creator.
Take care of your legal matters smarter, faster, and more fun
For Rulebooks, it doesn't matter if the legal work is done by a corporate lawyer or an external legal service provider. The Rulebooks platform ensures that legal matters are arranged as quickly and properly as possible.
