      I’m always impressed by the technical depth & breadth of SiliconMint’s engineering team and the passion they bring to our projects. We’ve worked with them on distributed systems, data science projects, and a predictive maintenance system for the oil and gas sector. Every time, they blew me away with their experience, passion, energy, and the overall dedication for how they approach software engineering and delivery.

      Web Development Review from Will McDonald

      I was able to dictate requirements at a high level without having to deal with the details. The Admios team was able to make technical level decisions on their own. They were a first class partner of the team.

    • Mark Griffin
      Mark Griffin Director of Engineering at Latent AI
      4.8

      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)

    • Matt Attaway
      Matt Attaway VP, Software Engineering at Off the Grid
      4.7

      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)

      Web Development Review from Andrew Burkhart

      I have been working with Emergent Software since January 2019 as our main website development and support service. They are professional, knowledgeable and flexible to our ever-changing needs. Emergent helped us seamlessly transition from our previous service and have been providing top-notch support since. From initial scope feedback and recommendations to collaborative build iterations to thorough QA, Emergent has been a solid partner and one that I recommend.

      Rick Mueller's Review Sourced from Google

      Our partnership with Emergent Software has been nothing short of amazing. Their attention to detail, communication philosphy, and technical expertise are second to none. The projects they have done to date, allow us to better deliver on our mission. We are looking forward to many more engagements to come.

      Steve Molander's Review Sourced from Google

      Oversight of our databases have always been a challenge. Finding the skillset to properly administer the systems is both difficult to find and high priced for a mid-sized organization. We reached out to Emergent to find out more about their virtual dba services. Their services sounded to be exactly what we needed. That was over 4 years ago. Since then we found Emergent to be a key partner in helping us in administration of our databases. Our systems are highly efficient, highly available and we feel secure knowing they are under the oversight of some amazingly skilled engineers.

      I recently had my website and brand rebuilt by Sam and I couldn’t be happier. He was so easy to work with and unbelievably quick. Every question I had was answered with patience and clarity, and he explained everything in a way that actually made sense. The whole process felt seamless and supported. I’m thrilled with the final result and highly recommend working with him.
