Mary Wells

VP Marketing, ASG Technologies

The Sigma team was amazing to work with. They were very patient and accommodating with me due to my lack of programming knowledge and time zone difference. I could tell their goal was to make me happy and deliver me the site I have always wanted.

Gary Greaser

Owner, Buried Treasure Fossils

Our webshop has been live for a while. Congratulations on the completion of the building of the TFL Web Order. I know how much time and efforts you all put into the designing of the solution, and I really appreciate the advice and attention you brought to the project. Thank you so much to the Sigma team for all the support and hard work. धन्यवाद!

Bahlinger Audrey

Global SAP Service Manager, TFL Group

It's been a pleasure working with the Sigma team. I've been impressed with the work and discipline the team has shown. Sigma has made a huge difference to NPP and has really been a stabilizing force. While it was a very difficult decision to move on - it was a little easier for me to do so by knowing that the company is in good hands with the outsourced partners NPP does business with, Sigma being chief among them.

Kamran Jafri

Chief Operating Officer & CIO, NPP

Hiring Sigma was a gamechanger for our company. Our efficiency and productivity increased dramatically. Sigma has great communication and performs work that meets the standard we are looking for.
Highly recommended!

Wesley Coleman

Executive Vice President, Excel Health

Sigma is the only team I would recommend to anyone looking to move [or improve] their ecommerce website. Their flexibility made our custom development requests pain-free and easy! Sigma was able to re-platform our website in a timely fashion and turn the ecommerce channel of our business into a meaningful, revenue-producing machine. I wouldn’t even want to imagine working with any other agency.

Connor Vogt

E-Commerce Manager, KELLY & HAYES

Our experience working with Sigma Infotech has been overwhelmingly successful and we are impressed by the technical knowledge of their developers. The expertise in improving our Magento website and solving complexities has allowed us to grow considerably as an organization. We wish them success in their future endeavors.
