Not entirely true. They used to sit in Saint Petersburg AFAIK, and it used to be all-Russian team at the beginning. The Czech address had been (not sure about now) just a virtual HQ.
It doesn't offer discounts, it sells experiences. It's like a special promo, maybe with a little discount, but more importantly there's something special about it - something bundled, a gift, a theme, a story, maybe you meet someone unusual who teaches you or shows you something, or it's regarded as high-class...
The goal is not to get repeat customers going to your shop, but to sell more on Slevomat. People use the vouchers as gifts for their close friends and family. If they liked the experience, they will reuse the idea as their own gifts.
Cloud gives you very good price for what they offer - excellent reliability, hyper-scalability. Most people don't need either and use it as a glorified VPS host.
Let me provide some context - in the Czech Republic the local alternative Slevomat is hugely successful and the businesses do like using it, because it actually does bring them repeating customers.
Slevomat is actually larger by capitalization than Groupon.
Practically everyone is talking about and using ChatGPT. I can't visit a bar without hearing almost everyone talking about it. It's everywhere in public transport. People are talking about it in dance clubs. People are talking about it at the post office. Grandmas at the convenience store are talking about it.
It's "the few" who are not taking advantage of it.
Nobody is shutting it down, this is just EU/Italy self-sabotaging :) the rest of the world will carry on at incredible pace they won't ever be able to match - or catch up.
