What our clients say

Bit Zesty were excellent at resolving issues that were left unfixed for years before. The sprint work they did, delivered a very complex new piece of search functionality. Bit Zesty really took the time to understand our needs and propose ways of working that fit with our organisation. They didn't hesitate to challenge our thinking, deconstruct ideas, and propose solutions we may have overlooked.
