Software Development Review from Michael S.
We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.
UI/UX Design Review from Anonymous
Azumo helped us migrate our existing UIs into a new framework, creating reusable components and the infrastructure needed for future development. The developer they assigned became a seamless part of our team, always punctual, responsive, and a great fit overall.

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)

Software Development Review from Claus-Peter Mueller
We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork.The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages. At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.
Web Design Review from Anonymous
Thanks to Infinum's website refresh, the client has seen an almost 100% improvement in their website's conversion rates. The team excels at project management, using the client's own proprietary tool and also Figma very well. Their proficiency in design, delivery, and client relations stands out.

Software Development Review from Anonymous
We had created a conceptual framework to authenticate and verify the provenance, transaction history, and authorship of blockchain-based NFTs. Talentica was brought on board to test and refine the concept from both functional and engineering perspectives, and later to build a Minimum Viable Product (MVP) aligned with the agreed specifications and constraints.
Software Development Review from Anonymous
For several years, the team was composed entirely of Talentica contractors. Since January 2022, I have been directly managing them. The Talentica team handled the admin tooling backend, which included multiple Python Flask services with Postgres and Elasticsearch. These services operated in a service-oriented architecture deployed on Kubernetes, using Istio for service mesh and Spinnaker for deployments.

Bryan Pratt's Review Sourced from Google
Mystic Media has been excellent to work with, offered great value, and their expertise and project management has been evident throughout the development process. We hired Mystic to take an idea and concept drawings through UI/UX and graphic design, programming and development, all the way to the market. They have met or exceeded all milestones, even with significant additions to scope along the way. We're currently in beta testing before release, and we are very satisfied with the entire experience. Mystic has earned my unqualified endorsement for anyone looking to develop their first app with them, as we have done.
