Groove Jones Reviews & Testimonials

VR/AR Review from Sam Rogers
The fine folks at Groove Jones really delivered with this project!See for yourself at https://4-h.org/clover/activities/rockets-to-the-moon/Our organization had worked with them before, but this was my first time...and my first time working with an AR project at all. Giving all the stars in all the categories isn't something I do much of, but in every way Groove Jones earned it.From the beginning, they got the intention and guided us through the choices needed to keep us within our fixed budget and immovable timeline. The team consistently delivered what we needed to get approvals from our internal and external stakeholders, and worked with us when we faced unexpected delays and technical surprises. We're just launched and already looking for the next opportunities to work with Groove Jones again! Totally professional, and totally fun :) They really made our team and our brand look good.

VR/AR Review from Amy Chao, CMP
The client had an exceptionally positive experience with Groove Jones. The agency delved into new technology boosting user experience, ensuring it aligned with the existing environment and was multi-channel compatible. Groove Jones in less than 90 days unveiled an interactive platform that was not only visually captivating but also had a striking impact. Throughout the journey, it remained communicative, promptly addressing modifications and infusing their unique insights. (verified via email)

VR/AR Review from Alan Fletcher
The client collaborated with Groove Jones on a challenging initiative, marked by a lofty yet vague objective and a pressing deadline. Discovered through online research and having no prior association, the collaboration swiftly took off. In merely three months, Groove Jones conceptualized and constructed a 20x16x10 Holodeck for the client's participation in the MWC event in Barcelona. (Verified via email)

Apadmi Reviews & Testimonials
Thomas Booth's Review Sourced from Google
I recently had an experience back in 2022 with Apadmi that I feel compelled to share and have debated whether i should post this. As a professional eagerly looking forward to an interview with Apadmi, I was unfortunately met with a series of disappointments.Firstly, the structured process I was initially promised for the interview was not adhered to. This lack of organisation not only threw me off but also made it challenging to present myself effectively and forced to do a presentation in less than 24 hours notice.More concerning, however, was my interaction with the Managing Director, not sure if he is still there. I found his demeanour not just unprofessional but outright rude. This was disheartening, especially coming from a leadership figure in a reputable company. I've actually never been so humiliated in the professional environment.It's important for companies to remember that interviews are a two-way process. They are not just about evaluating candidates, but also about demonstrating the company's values and culture. Unfortunately, my experience with Apadmi fell short of the professional standards one would expect, however i would say Marcus, one of the board members was a delight in my first stage.I hope my feedback is taken constructively, as it is intended to highlight areas where there is significant room for improvement in how Apadmi manages its recruitment process and senior staff interactions.
Steve Jackson's Review Sourced from Google
Fantastic team, you can rely on them always.. Robert a partner of Apadami is an exceptional individual who supported me with my project in a professional manner. With his excellent peoples skills he will look after you. The person you can rely on anything and keep you assured. Will always go back to Apadami.
Manoj Ranaweera's Review Sourced from Google
Apadmi's ability to spin out technology as separate companies is remarkable. A strong supporter of Manchester tech ecosystem, they became unbeatable in mobile category during the first three years of northern tech awards before it adopted a new structure and ownership. Another remarkable achievement is that the four founders have remained together during all these years. I wish them all the best.

Syberry Reviews & Testimonials
Andrew Stanifer's Review Sourced from Google
I cannot say enough good things about Syberry and the experience I had with them! The entire team was extremely customer focused and incredible to work with. They will without out a doubt be our continued partner and go-to for any future software development!
Parker Collins's Review Sourced from Google
Syberry is the best! I can't even find the words to express how happy I am with my experience. This was the first time my company created a customized program, so I was initially very hesitant and apprehensive about the project. Syberry helped us transform a very lengthy and involved Excel sheet containing a large volume of important and sensitive information into a program that streamlined a complex process into a highly efficient system. Rudy was my main point of contact, and he was with me every step of the way. I can't say enough good things about the team we worked with to develop the program. By the end of the project, it was very sad to see them go. We looked forward to our weekly meetings with our dedicated Syberry team. I already have plans to start another project with Syberry and am looking forward to it! Thank you again, Syberry Team! You are all the best!
Jose Basa's Review Sourced from Google
We've done multiple projects with Syberry and found them to be professional and effective. They utilize current development methodologies and have solid project management. They were able to deliver timely work and stay within budget - areas where other offshore firms I've used struggle. I highly recommend them for any of your future technical projects.
