"I'm actually 130% satisfied, so you won't get any suggestions for improvement from me."

Elli Holappa
CEO at Jungle Juice Bar
"We have been very satisfied with the collaboration. Milla, who joined us as Financial Controller, quickly settled into the responsibilities, routines and monthly processes of the role. She also played a key role when Certego was separated from its parent company in connection with the acquisition and we launched a completely new reporting model for the Certego Group."

Akseli Alinikula
CFO at Certego
"We can highly recommend the services NIS offers, and if necessary, we will definitely use them again. We also gained a happy and pleasant colleague to our top team!"
