Yep, we've moved the HQ to Cyprus a couple of months ago.
There're quite a few reasons for doing it.
1. Cyprus is in EU and EU privacy laws make us (as an ad blocker) feel much more comfortable than any other place.
2. Currencies conversion. AG is a global product and selling it from Russia leads to losing a lot.
3. Tons of small but annoying limitations and restrictions. For instance, Russian PayPal automatically blocks accounts with more than $10k, you should keep an eye on the balance and withdraw funds to not allow this situation.
4. Relatively (comparing to other EU countries) low taxes for IT companies and IP Box regime.
5. Fewer "KGB" accusations
