More work, by sector

  1. 01

    Digital health company

    01 AI on your own software
    What was there
    Their data in their backend, and clinical staff who had to open the interface and click through it to look anything up.
    What we did
    A connector on top of their backend with credential-based access: staff ask and get the answer without opening anything.
