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.

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.

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.

As a marketing consultant I've worked with a LOT of web agency's over the years. Solve is easily the best. On launch one of our directors said "we've now got the best website in the industry". It's not just that it looks great, it's responsive it's getting us leads AND they are proactive in keeping it up to date, secure and optimised too.(Oh and did I mention they're great guys to work with?)

Literally cannot praise the work and team enough. The amazing and very talented team worked tirelessly with us throughout the entire process and the finished website is beyond our expectations. We are absolutely thrilled with it, we especially loved the process of working with the designer and tech team - who heard our brief and worked with us to tweak it to our needs. It was absolutely a fantastic and speedy process and we cannot wait to see how much this will bring in new customers. Thank you Solve. Literally would recommend to anyone wanting to rebrand!

Barri has a great understanding of marketing strategy and social media. I really valued his insights, particularly around using social platforms to generate leads, which led to more traffic and enquiries through my website. He also helped me set up analytics tools, which have given me a clearer view of what’s working in my marketing. I appreciated how responsive he was whenever I needed to talk something through, and he’s a genuinely nice guy who knows his stuff.

Richard Packman's Review Sourced from Google
Barri is a great guy to work with. He really knows his stuff, and is very friendly and approachable too. Felt more like an extension of my team than a freelancer. We used him for some AdWords and Analytics assiastance, and customer acquisition strategy. He was very quick to respond and deliver, and very transparent and a great communicator throughout the project. I wouldn’t hesitate to call on him again. Thanks again, Barri!
