Building strong partnerships with…

Increasing aid transparency is the mission of The Open Data Company as Data4Development (D4D) & Zimmerman (Z) are now joining forces. The Open Data Company provides online data services to enable international development organizations to become more data-driven.


Zimmerman is specialized in providing data services and building data visualization platforms using open data standards like the International Aid Transparency Initiative (IATI) standard. 

Data4Development is working with clients to support them in their aid data publication process using IATI. 

Together we believe in the potential of high-quality data for increased aid effectiveness. With our Aid Information Data Analytics platform (AIDA), we enable NGOs and other parties that receive aid related funding to explore, produce and use their data in order for the organizations to back up their results with solid data.

Toladata is a cloud-based monitoring and evaluation platform (based in Berlin) that supports monitoring and data management with tools for planning, tracking, aggregating and reporting results in real-time. 


TolaData has been built for monitoring development projects and provides robust end-to-end indicator management.

Toladata combined with our Spreadsheets2IATI services delivers seamless International Aid Transparency Initiative (IATI) compliant reporting. It is now possible to export all indicator results across all projects in line with the IATI reporting requirements. 

Joining our forces can help our mutual clients with a powerful and easy to use solution for project data management as well as their IATI reporting.
