About Cumul.io | Empowering everyone with smart decision-making

We lead organizations to success, one insight at a time

Smart decisions for everyone. Not just the elite few.

As corporate consultants, Karel and Haroen grew frustrated with the complexity, cost, and long cycles of traditional BI projects. Smart insights were a privilege to companies with millions to spend. Fast forward to 2015. Together with Thomas, they launch Cumul.io to empower anyone to make smarter decisions. From the skyscraper office to the restaurant down the block. And the early founders knew exactly how to spread these bite-size insights to millions of people fast… By surfing the booming wave of Software-as-a-Service.
