Selleo Reviews
Submit a review- Redesign WidgetProject Type: eCommerce DevelopmentReview Date: 9 January, 2023We 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.Rating:
