Web Design Review from Alyssa Brenke
Specifically, working with Ben was amazing! He was incredibly responsive and answered all my questions throughout the process of updating our website. Our original site was built roughly a decade ago (or longer) so we were in need of some streamlining and modernization. The team did just that and quickly! The first iteration was spot on for what we were looking for. Not to mention, they were able to launch quickly and without any interruption to our daily operations. Would 100% recommend [it]!

Mobile App Development Review from Dr Asa Frey
They worked on our app and continue to work on it to this day. We originally had a bad experience with various developers and ended up with a bunch of code and no functioning app - touchzen took the code and audited it and made it work and it work great now. Can't complain - still going to work with them and I would recommend to anyone who wants it done right.

Software Development Review from Mark Griffin
Due to past experiences, Latent AI is always cautious when hiring external engineering resources for a project. But collaborating with Admios is a breath of fresh air. The agencys account manager is nothing short of professional, attentive, and understanding of client needs. Furthermore, Admios seasoned and self-sufficient engineers fit seamlessly into the Latent AI culture. The team treats and trusts them as one of their own. (Verified via email)

Mobile App Development Review from Matt Attaway
Off the Grid has had a longstanding developer partnership with Admios. Recently, the client trusted Admios with building a complex React Native POS system and a guest order-ahead app. Given the complexities of the project, Off the Grid wouldn't have chosen any other agency to work with. The Admios' developers did an excellent job, the management was proactive, and the software quality is exceptional. Admios is highly recommended. (Verified via email)

IT Outsourcing Review from Wiljen van den Berg
Xduce was very complient at first, but quickly made it nescessary toput in more money, for obviously a bigger reward. When the target was achieved and my funds should be returned including my reward, it became nescessary to deposit mor money to finish my last assignment and free the funds. When i pointed out the system itself notified the i couldnt continue (with screenshots) my "mentor" Kevin 044 7782 608823 (save this number) started to mock me, lie to me and later on threaten for defamation. When i talked to Customerservice they did pretty much the same, until i struck a nerve, after which to mock me they told me "there is no money, you will not get get paid if you complete the task. I have all the screenshots to prove my case. please contact me to settle this at wiljen.vandenberg@wf-ib.de
