Our clients

“I have the opportunity to work with some really talented Xenzu’s employees at SugarSync. They have been part of the engineering team for more than 4 years showing commitment in relationship and relentless performance for an off-shore team. We found them technically sound, self-motivated and very good team players. I would recommend them as potential off-shore resources for any suitable team.”

Engineering Manager, Desktop Client and Platform at j2 Global

Subbu Satyanarayana

“Xenzu was able to provide us with an awesome iOS/Android development team. They were diligent, self-directed, smart, knowledgeable and very pleasant to work with, even if remote. Code craftsmanship was also very good, and they served as an excellent platform to also test our ideas with.”

Chief Technology Officer at Thinglink

Janne Jalkanen

“XenZu was instrumental in the success of the Poynt solution. The highest quality software and hardware development services combined with extremely talented employees with a dedication and focus on customer satisfaction. I highly recommend XenZu for the services of sustaining of your legacy software as well as new product development.”

Vice President at Poynt Corporation

Bart McCormick

“I was looking for a team to develop a mobile application that connects to an innovative piece of hardware. Xenzu Technologies came highly recommended by a few companies in my area, and they were right. With minimal explanation, the engineers where able to conceptualize and implement the functionality of the device. They asked all the right questions, and even taught me thing or two about my new device. The coding was impeccable and the application is very stable. This is due to the extreme skill and professionalism of the engineers. The engineers kept me informed with weekly status reports, emails and with real time information (they had no problem chatting with me at 3am). XenZu wrote the application for J2me, but I plan to have them port the app to other platforms.”

CEO at CellAssist

Hendalee Wilson

“We initially contracted XenZu to port our existing BlackBerry message archiving application onto the Symbian S60 platform. They demonstrated a clear understanding of the scope and requirements, based on very limited documentation from us. In addition, they were extremely communicative, both asking relevant & insightful questions, and keeping us informed of their progress throughout the whole process.

XenZu is absolutely unmatched when it comes to quality mobile development per dollar.

We are planning to continue working with them on the S60 platform.”

Director, OEM and New Platorms at Magmic Inc.

Troy Johnson

“XenZu deliver the whole next level of development partnership beyond “outsourcing”. Zvents used XenZu’s team to build mobile applications that we had decided were critical to our future, but not at the top of our priority list for our own software development resources. We were quite an accomplished software development team in our own right, so our standards were extremely high for both process and product; and XenZu team met or exceeded them in all respects. The entire relationship felt far more like a remote employee team than it did any form of “outsourcing”. XenZu works very hard to deliver that level of communication, coordination, and execution, and it works. Highly recommended.”
Top qualities: Great Results, On Time, High Integrity.

CEO at Zvents Inc.

Ethan Stock

“XenZu team impressed us from the start, delivering a realistic project plan and then hitting each of their milestones on-time and on-schedule, working step-wise with our development team. Their expertise on *Nokia Symbian Series 60* development was evident in the final product, which has since gone on to delight our end-customers. I would recommend XenZu to anyone looking to do mobile client development.”
Top qualities: Great Results, Expert, Good Value.

Product Management at CounterPath

John Craig

“We hired XenZu to manage the hiring and operations for our outsourced development team. XenZu did a fantastic job sourcing highly skilled engineers for us very quickly, in any area that we needed (mobile and server-side development). XenZu project manages the team very well and constantly monitors the progress of each engineer, resulting in an on-time delivery of products. XenZu provides very responsive service and handles our concerns in a very timely manner. We have dealt with other outsourcing firms in the past and XenZu has provided the best service and results to date.”
