    Founder at Zetya Pty

    Redesign Widget
    Project Type: eCommerce Development
    Review Date: 9 January, 2023
    We hired Selleo to do a redesign of our app. Poor communication, repeated missed timelines and a very poor quality of the small items that were delivered. Anna (Head of Business Development) ironically kept asking us if the "project was on track" and if we were "happy" with the project and despite our negative feedback did nothing to get the project back on track. We eventually fired Selleo after wasting $20k on this project. I would not recommend using Selleo.

    The client couldn't be happier with the services that Selleo's provides. The team takes full ownership of their work and they continue to pursue the best tools available to maintain the platform's security and scalability. The communication is transparent throughout the development.
