Our Story

First launched as a multi-channel publishing platform in 2004, Tangelo evolved into a powerful annual reporting solution by 2011. It was around that time that co-founder Erwin Groenendal crystallized the company’s mission: to make life easier with a better way to produce corporate reports in-house.

Since then, Tangelo has rapidly expanded from a solution for leading Dutch companies to a platform for enterprises and organizations across the world. With operations in The Netherlands, New York, and Sydney, Tangelo serves clients in Western Europe, North America, and Asia-Pacific.

Today, Erwin is a recognized thought leader in the investor relations (IR) space—frequently presenting and sharing original research on digital IR practices at conferences and events across the globe.
