What our clients say

I was very impressed by the project management acumen on this eCommerce project. On every meeting I had with you, it was evident to me that you were in complete control of your domain – great job!

Charles Nartey Project Manager
Working with Zoonou has been a dream - they have felt like an extension of our team. They understand what we are trying to achieve and the business goals for our clients.

Andy Eva-Dale Technical Director
I've been doing this PM thing for sometime and have to say that your team have been the best I've dealt with.

Eugene Dunkley Senior Project Manager
From the very first meeting, you were professional and knowledgeable and had the right people on the call to be able to answer our questions. You made it really clear as to what the services included and had a very straightforward plan.

Rob Barton Head of Product
When it came to QA we needed the experience and resources of a large team without needing to recruit and build that team in-house. Zoonou had a wealth of experience and enabled us to set up a well rounded testing regime within days of their introduction to the team.

Mark Ward Chief Technology Officer
The project went really smoothly thanks to excellent communication on Zoonou's side. The final reports were clear and well presented. Overall we were extremely happy with how everything went. Big thank you to the team!

Danny Currie Technical Lead
I’ve worked with many other external QA companies, but they only do as they’ve been asked. Zoonou go way beyond that – they are proactive with suggestions and ideas on how to improve processes. That’s what makes this such a great partnership.

I'm a huge fan of Zoonou. QA is thorough, tickets are very clear, communication is always clear and timely, and initial engagement is always smooth, and there's flexibility when we need it.

Our overall experience with Zoonou was excellent and I would highly recommend them to other small public-sector bodies working towards compliance with the Accessibility Regulations.
