Software Development Review from Michael Meyer

We were so positively surpised and happy about Sigmas services - as usual I might add. It is a pleasure working with their software engineers. After we provided a briefing, the effort estimation came right away. Shortly after the project started we could see first tangible results. The code quality was excellent and comprehensive. Minor feedback was implemented right away. What can I say more: 10 out of 10 points!

As a RingCentral partner, Unity Communications provides one of the best sales support teams for technology for companies. The client's projects involved handling different customers types from large enterprises to small businesses, implementation, and customer service. The Unity team did a very thorough job handling intricate technical demands that involved research, spreadsheet details, proposals, and immediate response when required. Very detailed.
