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!

Joseph Lopez's Review Sourced from Google
The rep Laurianne Usanase snuck a meeting in my calendar and her team tried to ambush me with a sales presentation. I think they are just randomly inviting people to meetings, hoping they accept and then hoping they can force a sale. I am not sure how they thought that would work but it took 15 minutes of my time to figure out what was going on. This was pretty awful and underhanded.

I bought new computer with windows 11, couldn't get email working, not one three email accounts! I called tech support for my web hosting (Pacific Software Publishing, Inc.) to help with my website based email. I think his name was Joshua, and he got my email accounts up and working with my Outlook email software. He was going so fast i could hardly keep up with the cursor on my monitor. This guy is GOOD!
