michelle G digital marketing specialist at G&M Orient
5.0★
UI/UX Design Review from michelle G
The quality has been excellent. Working with Nurency has been really good. We come to them with ideas and they work through the processes. After some back and forth, they improve upon what we gave them. We dont have any quantitative data because we havent fully deployed the solution. The project management has been great as well. The person we dealt with was on top of everything. They kept up to date with timeline and budget concerns. We used some tools during the design process, but nothing was set.
Rohan S US IT Recruiter at USM Business Systems
5.0★
UI/UX Design Review from Rohan S
We provided Nurency with our idea and vision of what we wanted to accomplish, who the users of our platform would be, what value we wanted to provide to each user, and what features we wanted to implement. After that, nurency held a series of workshops, where we put together a list of features, inputs, and outputs. Based on that, they were able to give us the flow and options for the UX, as well as what the screens would look like. Their team also engaged with our potential customers; they had interviews with them to validate our business plan, including the features and functions. They gave us feedback on the value that our customers were looking for as well. They were able to map everything out in the UI/UX using Figma.
Andreas Birnik Co-founder at evroc
5.0★
UI/UX Design Review from Andreas Birnik
Nurency is providing us with UI/UX design services. They're optimizing our existing solution and all its underlying constraints. The team has worked with our technical and engineering teams to ensure they understand the challenges of our backend and then interpreted what we needed for the frontend design. We started with a UX research phase where we did outreach to existing customers, and they worked to go through our existing UX to map out all the essential features that needed to be deployed.

Dementia Sings Out Choir Admin's Review Sourced from Google
I cannot thank Olly and SEO Moves for everything they have done for our Charity. They have guided, advised and steered us into developing a website that we are all absolutely delighted with. They have allowed us to develop our own ideas and then implemented them in a professional and easy to navigate way. Olly always responds promptly and with professionalism and no question is too trivial. The trustees of Dementia Sings Out have no hesitation in recommending SEO Moves for any of your website or marketing needs.

Jason and the team have been fantastic with us. Their SEO work has significantly helped us become more prominent in Google. We're not experts, but they are, their patience and support has been great, taking time to explain what they're doing and most importantly why. The whole experience has been a pleasure, we wouldn't go anywhere else.

David Harris's Review Sourced from Google
I have been scammed by a copycat Scammer pretending to be this company in a work from home scam. I spoke with Paul the CEO who gave me chapter and verse on who these scammers are and what he has had to do about. I am more than happy to place on record that my problems have nothing to do with Paul's company and he has been more than helpful in providing information that will help me recover my lost funds.
