We tried to hire devs in Switzerland for a very long time. We were lucky to find Mobilunity who recruited and hosts our nearshoring dev team in Kyiv. We are very grateful that we have a partner who meets our tight scaling goals.

Philippe Lautier

I worked with 2 companies: 1 very big one and I worked with Mobilunity. And honestly, I preferred Mobilunity because the go beyond just providing resources. They establish communication and a deep understanding of your own culture.

Eduardo

Our problem was is that we wanted to develop a new application and we didn't have the resources. So we contacted Mobilunity to try to be able to develop this application with external resources.

Mirko Lagattolla

At the very beginning, we were looking for a mobile development firm. We were specifically looking for vendors that we could trust. That's definitely what we found when we were working with Mobilunity.

The dedication of the Klevu Ukraine team to delivering top-notch service has truly set a standard for excellence.
Especially during challenging times like those Ukraine has faced, the commitment and resilience demonstrated by the engineers have been outstanding. Their unwavering dedication has not only contributed to the success of our projects but has also showcased the strength of our partnership during difficult circumstances.

When one of our development team members passed away unexpectedly, and the release timeline was looming,
Mobilunity was able—within days—to provide a full-time resource to pick up the work where it was. The entire process was highly professional and needless to say, the gentleman is still on our team, and we added more resources from Mobilunity to our team. Working with Mobilunity technically and personally has been, and continues to be, a great pleasure.

Mobilunity takes a lot of weight off my shoulders by taking care of such HR things, as employee mental health check, performance appraisal, work anniversary & Birthday reminders and actual goodies delivery.
Those may sound like tiny things, but we all understand their huge value to the employees. It’s reassuring to know that someone close by is attentive to our team.
