I am a representative of Yandex.Money(YM) and YM is the top1 payment service in CIS region.
As I have noticed, almost 5% of your audience that was identified by the SimilarWeb, comes from Russia. I assume, there are even more users from the CIS region. Right now, over 40 M people use Yandex.Money for covering payments in all kinds of services: e-commerce, online games... We have also started cooperation with Streaming srvices and that is why I am writing you the letter: to talk through the oportunities of cooperation for using YM as a payment method.
We work with http://www.donationalerts.ru/; BIGO and KWAI.
