Business optimization involves more than optimizing resources. It requires awareness: you not only need to identify your weaknesses but also ways to overcome them. With the latter, you might have to face some challenges. But if you find the right partner who is a true expert in their field – progress comes naturally. This is why we entrusted a big part of our business to Mainstream, moving some of our operations into the Mainstream cloud.
