    • Sam Rogers
      Sam Rogers Project Manager at National 4-H Council
      5.0 ★

      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)

      Alan Fletcher Chief Product Officer at Aurea Software
      5.0 ★

      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)

Sources

DesignRush sustains a directory of over 30,000 agencies categorized by service category, location, expertise, and reviews. We build our database in two ways:

  • Our dedicated team of agency experts actively searches the web for top-performing companies. We then pull information from their websites, online presence, and client testimonials to verify their status and qualifications prior to listing.
  • The agencies listed get notified of their profiles on the website and they can choose to claim it or not, which suggests their availability for more collaborations.

Agencies can also reach out to DesignRush and must go through the verification process prior to being listed.
