      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 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.

      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.

      After working with Webisoft for a few months, I'm really pleased with the caliber of support and output I've had. I manage a little business, so I'm highly involved. I am aware that I have managed previous marketing companies a little too poorly in the past. However, Webisoft has shown me a great deal of patience and has taken the time to comprehend my unique demands and create a plan to address them.

      Pratiksha Tiwari's Review Sourced from Google

      We needed a custom software solution tailored specifically to our business operations, and finding the right software development partner was a crucial decision. We were initially unsure whether a Noida-based company could fully understand our unique requirements and deliver a scalable solution. From the beginning, the InnovationM team demonstrated a deep understanding of our business challenges. They took the time to analyze our workflows and proposed a solution that was both practical and future-ready. Their structured approach gave us confidence in their capabilities. The final software solution was reliable, efficient, and perfectly aligned with our needs. It helped streamline our operations and improve overall productivity. We are extremely satisfied with the outcome and would highly recommend their services as a trusted IT services and software development company in India.
