What people said about Sidera

We have an excellent working relationship with the Sidera agency. They know how to listen to our wishes and how to guide us when we run out of them. Sidera girls are quick, creative and proactive. They are distinguished by their extreme attention to details. Sometimes, they produce excellent content, really beautiful and meaningful, out of almost nothing. At the same time, they never forget that efficiency is the main measure of success.

Maja Knežević, Regional Marketing Manager for Honor, Huawei Technologies

We carried out two different events with Sidera agency - one was intended for the media and bloggers, the other one was intended for the general public. Both times the organisation was carried out professionally and with a soul. What particularly persuades is an economical attitude of how to do as much as possible with the least resources. Urška also impresses with her enthusiasm and warmth with which she discreetly weaves acquaintances and builds an effective social network that is priceless when it comes to PR. I recommend this company!

We started working with Urška at the beginning of our business journey. With her help we have gained creative power, have found solutions and have built an active collaboration. She is a reliable partner who listens to the demands and desires of her clients.

Branka Cvjetićanin, B.A. in Economics, Director at VivaDerm d.o.o.

From the first moment of our collaboration, Sidera has shown amazing positive energy and attitude towards our brand. Urška is a unique person who always devotes even more energy and effort as expected, and thereby achieves brand exposure in all mainstream media, both in printed and online media. With a great desire to contribute to the changes in the market, with an excellent relationship with the media and with the understanding of the main goals of the brand, Urška always surpasses the outlined plans. Urška’s personal attachment and dedication to her partners and their brands are invaluable.
