Software Development Review from Adam Kaufman
The team at Sembit and their work product has been nothing short of stellar. The team is a delight to work with. We have actively looked for more projects for them to work on because their deliverables are timely and of high quality. Sembit started out doing a mobile app project for us, then they grew to doing our Playground project for our effcc Compiler. They have also done a number of backend systems projects as well. The Sembit team are trusted advisors when we need to deploy a new system or work on a new project. Sembit will always be a go-to partner.

Working with Media Components for the Lighting Loft grand opening was a pleasure. From the start, they were attentive, understood the vibe I was going for, and captured every important moment—both in video and photos.

The Renaissance team is awesome! We're an ad agency that partners with them to round out our capabilities, and they've always over-delivered. We've white-labeled, blue-labeled, and co-labeled with them, and they work just as hard and deliver great performance no matter the arrangement. Their buying capabilities are extremely competitive, and their analytics are cutting-edge and comprehensive, so we plan to keep working with them on every project that makes sense. Highly recommend!

Jim G's Review Sourced from Google
As the owner of a commercial construction and maintenance company I have constant communication challenges…getting updates from the field, tracking materials, managing hours. It was eating up way too much time for everyone involved.We brought Epic Apps in to solve that, and they delivered on every front. They built us a custom private tablet app that our field crews use daily to order job materials, log hours, and submit job updates; and an internal website that doubles as an employee feedback hub, which has genuinely improved how we operate as a company.The whole team was professional and responsive from start to finish. If you're in the trades and looking for a development partner who actually gets your industry, Epic Apps is the real deal. I highly recommend them!Jim GagnonOwner – NorCal Construction & Maintenance Inc.
