Designli Reviews & Testimonials
Mobile App Development Review from John Laporte
Designli helped us define the requirements, features, and user experience for an app for our motorcycle organization. They produced technical documentation and a clickable prototype covering navigation, member tools, and safety features. They were responsive, delivered on time every time, and turned our broad concepts into something people could actually click through. The prototype got our stakeholders aligned, earned internal approval, and set us up for engineering, and working out design questions early should save us rework later.
Mobile App Development Review from Brandi Heffner
Designli built our SaaS product from scratch, using AI to speed up development, with AWS and Cloudflare in the stack, and they also handle our hosting and maintenance. We had a working MVP in just 30 days and have kept adding features since. In the first 60 days they went beyond what we expected, largely because they took the time to really learn our business and our market. Coordination through Basecamp and Google Meet has kept everything organized.
Mobile App Development Review from Thomas Simmons
Designli took over app development and marketing for our driving school, with the goal of building a product we could eventually offer to other schools. Within two and a half months, the app was up and running in our own school. Their project management is excellent, and they push back constructively, thinking through what we actually need instead of building every request as-is.

ELEKS Reviews & Testimonials
Software Development Review from John Armstrong
ELEKS was able to take our vision and help us deliver an app that empowers retail shareholders to make their voices heard. They’ve brought a depth and breadth of technical expertise and user experience design to challenge us on our assumptions on how people would want to interact with the app. From a mobile development perspective, we wanted to go to market with both an Android and an iPhone simultaneously.
Software Development Review from Mark Battcock
We are very happy with our ELEKS partnership; the dedication of the team is exceptional. We would certainly recommend ELEKS and would be happy to work with them again. In fact, they continue to be our partner for the 2nd phase of the CDX project to add even more customer services to the website.
Software Development Review from Huntly Christie
What impressed me about ELEKS is the culture. There is a very strong culture of discipline and performance, and software is a profession where discipline is very important. Good software development can only happen with a strong work ethic, and I think the ELEKS team really understands that.

Takeaway Reality developed our custom software exactly according to the specifications we provided. We shared images and videos with them, and they transformed that into a VR platform where people can view their apartment or house. Users are able to explore the property through a fully virtual walk-through.
Mobile App Development Review from Marie-Laure De Veyt
We set out to build awareness around a new cyber safety product. After reviewing several agencies through an RFP, we chose TAR because they fully understood our objectives and had a clear plan to achieve them. From brainstorming to final execution, we collaborated closely and collected feedback in an organized way. Working with TAR has truly been an outstanding experience.
VR/AR Review from Erik Matosevic
We were informed about every major step in the process and it really made everything much easier. Takeaway Reality’s work delighted the client. Their dedication to the project accentuated their deep and relevant knowledge of VR and AR. Their communicative and transparent approach resulted in methodical project management. They went above and beyond to optimize the solution.

Monica's Review Sourced from Google
Amazing and talented people. I’ve worked for both client and agency side and can can say their partnership is amazing. They truly care about ongoing operations and not just ending it at a project level. Highly recommend! Message me if you want specifics.
John Andesilich's Review Sourced from Google
I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.
