We partnered with Diffco for a comprehensive software development project aimed at delivering a mobile application and backend system for our client.

Mobile App Development Review from Angie Tromley-Morales, PMP

We hired Empat to design and build the MVP of House Caddy, a household management app that keeps receipts, warranties, manuals, and repair history in one place, with reminders for expiring warranties and maintenance. The product also helps homeowners prepare a full digital home history for future property transfers. Empat delivered end-to-end work: discovery, UX/UI design, Flutter mobile development, and a Python backend. They implemented a clear flow where users first create home appliances/systems and then attach documents and repairs to each item. A major highlight was Empats AI expertise. AI features simplify the entire user journey by auto-filling appliance details from photos/docs/links, assisting with utility provider setup, and importing contacts to speed up adding contractors. This reduced manual input and made onboarding fast and intuitive. Communication was excellent, with proactive brainstorming, clear sprint updates, and on-time delivery. The MVP is market-ready, early feedback is very positive, and Empat proved to be a reliable, product-driven partner with strong mobile, backend, and AI capabilities.

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.

In addition to building out a native remote inspection app for iPads, Zco concurrently ported the software to a Xamarin platform for Windows users.

Web Development Review from James Leonard Ehrlich, DVM

I wanted to outsource front end development while maintaining back end services myself. They started with existing React SPAs, cleaned them up, found and removed bugs, improved user interaction, made clear requests for new endpoints which I implemented and they tested and used. The time difference between my office in eastern USA and theirs in Moravia worked well, as we could meet at their afternoon/my morning and I had the rest of the day to deal with back end or questions they might have. Their professionalism and competency were impressive. I will continue working with them, for years, I hope, in maintenance mode or when we need to expand features.
