Mobile App Development Review from Julia Platova

We partnered with Diffco for a comprehensive software development project aimed at delivering a mobile application and backend system for our client. The goal was to create a seamless, secure, and scalable solution within a 4-month timeline and $50k-$200k budget. Diffcos team was highly professional from start to finish. They handled everything: UI/UX design, backend architecture, API integration, and deployment. After the launch, they continued to support us with maintenance and performance optimization. The application received positive feedback and has proven stable and scalable. Were highly satisfied with Diffcos expertise, commitment, and ability to deliver real results.

UI/UX Design Review from Wladimir Wolinski

Communication was smooth either through our teams communication channel or with the project manager via email. We were in daily contact with the UX/UI designer in form of dailies or when we had to clarify some questions. With the project manager, we had a short conversation every 2 weeks to clarify all possible questions. We personally love to work in a very process-oriented way. Because when we understand how to do something, we usually know how the end result can look like. With Digis, we also had the feeling that they knew what they were doing and how to do it. Every next step was planned from the beginning. If something didn't work in line with our processes, we could readjust it. We were basically satisfied with everything.

Mobile App Development Review from Gina Levy

Both the developer and tester have exceeded expectations. Their performance is excellent. Together they eliminated bugs, introduced new features, and ensured that the app is working without problems. Previously, we had many complaints in the app store. Since working with this developer and tester, these complaints about the app functioning and bugs have disappeared. The time zone different is sometimes challenging, since we are in California and they are in Europe.

Software Development Review from Dominique Dujardin

The product was developed successfully and has been undergoing pilot usage. Hexagon IT Solutions managed the engagement effectively, delegating tasks and assignments between us and the team. They met timelines and communicated efficiently through Slack. Their resources also resolved bugs quickly. Hexagon makes it easy for people trying to develop software. Ultimately, Hexagon was and has been on the same page with us from the beginning. They knew exactly what we were looking for, and what we didn't want. Other software development firms jumped at us with marketing proposals, designers, and irrelevant business consulting. Hexagon IT Solutions took the time to understand who we are and offer us their services accordingly.

Web Development Review from AJ Canty

We’ve been working with Vention for quite some time and consider them an extension of our team, rather than an offshore vendor. We needed solid mobile developers to work with our in-house engineers to build our Primer SDKs on both mobile platforms. This was not a trivial thing as it required a lot of cross-functional communication, but the Vention team was up to the challenge. They quickly adopted the best practices we follow at Primer and proved to be effective and proactive.

Web Design Review from Christopher Calarco, D.C.

Our company had an excellent experience partnering with Jeremy and the 97 Switch team on our website and SEO. The initial build was on a tight timeline that was kept, and after the sites completion we saw a significant increase in new business coming our way. More medical professionals learned about us and wanted to join our network, which was an amazing bonus of working with 97 Switch. We've committed to work with 97 Switch for the next several years given they have been crucial in guiding our plan for growth.

Web Design Review from Justyna Chrupek

We hired them to build a new website. The website was quickly completed in just a couple months, and weve seen markedly positive results from 97 Switchs efforts. It's a new marketing feature that we use on a daily basis. The improved quality has facilitated our communication and made things much easier. Weve received great feedback from our vendors, investors, and customers who want to view our properties. Internally, our staff is excited to see what's going on in our company. We are definitely proud of our new platform. Our executive team is excited to be featured on the new website; previously, they didn't even want their picture shown. Before this redesign, we were almost embarrassed to send out the link. Now, we can comfortably share it with our investors, potential investors, and landlords so they keep track of our updates on a monthly basis. We love how this site presents the face of our company.

Web Design Review from Adam Greenberg

We've seen tremendous growth and exposure. The website has generated a number of new leads and weve received tons of cold calls from potential clients. This is thanks to 97 Switchs efforts to increase our digital exposure. We communicate primarily via phone and email and theyre highly responsive. I receive a response to emails within minutes and they get back to me within half an hour if I request a phone call. They're able to conduct face-to-face interactions in order to truly understand the goals and business culture of their clients. This allowed them to create a design that accurately represented our brand. I've had nothing but positive experiences with 97 Switch and Id recommend them to anyone.
