Zco Corporation Reviews & Testimonials
Mark Gratiot Director of R&D at Streamline Automation
5.0★
Cross-Platform Review from Mark Gratiot
In addition to building out a native remote inspection app for iPads, Zco concurrently ported the software to a Xamarin platform for Windows users. Zco has released nine major iterations of the iPad app, each available in the App Store, as well as the initial version of the cross-platform Xamarin build. Their nimble team boasts a wide breadth of skills to match any given situation. Having clear documentation upfront has reduced onboarding time.
Katie Matter Project Manager at Southwestern Advantage
5.0★
Mobile App Development Review from Katie Matter
Zco Corporation provided full-stack mobile app development to an educational resource retail organization. They worked in Unity to build a cross-platform resource for users to advance through various curricula. The app has successfully been moved into preproduction and the second phase of development, completely satisfying project stakeholders with the quality of both its designs and functionality. The Zco Corporation team is highly creative and collaborative throughout their work.
J. Michael Webb CEO at CheckMySpot
5.0★
Startup Review from J. Michael Webb
J. Michael Webb from CheckMySpot chose Zco Corporation for app development due to its expertise. Zco adeptly developed a hybrid mobile teledermatology platform and an admin website, demonstrating excellent communication, responsiveness, and innovation. Despite the project's evolving and innovative nature, Zco seamlessly integrated Webb's intent and met all challenges, leaving him with no suggestions for improvement. (Verified via email/call)

The Utah Tech Lab organization has been much more than a contractor to us. They’ve been our partner in developing a secure and technologically sound application. Their insights have been more than valuable. I recommend them to anyone.

Emily E's Review Sourced from Google
If I could give Utah Tech Labs zero stars, I would.Let’s start with Russ—“the state’s top guy in AI.” At least, that’s what they tell you. But you’ll never meet Russ. He’s just the closer, the guy who sells you the dream. Once you sign on, Russ vanishes, and you’re left dealing with a team that simply cannot deliver.Over 12 months, they failed at every aspect of the project. Not one promise kept, not one deadline met, and not a single budget adhered to. They took over $70,000 of my money, and after a full year, I have nothing to show for it. Not even a keyboard. Not even an app. They literally could not build a keyboard—one of the most basic tools in tech.After being charged over 20K in two weeks and complaining that not one thing had advanced on the app, none of my concerns were addressed. However, a month later, their overseas "tech team" was fired for not doing any work when they billed. However nothing was reimbursed.The sheer incompetence is staggering. If you enjoy missed deadlines, vague excuses, and a complete lack of accountability, Utah Tech Labs is the place for you. If you actually want results? Run the other way. Fast.
