    "D4D helped us with implementing a new application, and I was happily surprised with how quickly we gained extra functionality from the Finance Module. I had expected that the work for our colleagues might be a bit simplified in a year from now but now getting a financial report was already very easy! I definitely saw the Finance Manager smiling broadly as a result of the work done so far."

    "Data4Development helped us to properly structure our IATI publications and set us on the right path for growth with our Regional Offices publishing independently."

    "D4D helped us out in a good and professional way when we were looking for an efficient solution to making our Caritas Europa mapping system IATI compatible earlier this year. With their vast IATI experience and understanding of the international NGO sector, D4D immediately understood what our needs were as a European -, and global NGO network. It has been a really smooth cooperation process and I highly recommend D4D!"
    Miriam Pikaar
    Programme Manager - Caritas Europa
    “Without doubt the team from Data4Development enabled Concern Worldwide to achieve data transparency on all DFID grants. Until we brought Maaike and the team on-board, we struggled to understand the data structures required to upload data to the IATI Registry. The whole project took a huge leap forwards towards completion with their help.”
    Bernard Gaughan
    Head of Information Systems - Concern Worldwide
    "The collaboration with Data4Development went very well. They definitely had a custom approach which adjusted to the needs of our alliance and responded quickly to our questions. It was difficult at first to navigate through our extensive data, but in the end we were happily surprised that the job was done relatively quickly!"
    Odilia van Manen
    Programme Manager - Her Choice
