I've always had the impression that Ukraine's tech sector is primarily focused on outsourcing or outstaffing for Western companies, so they typically don't own what they build (and it's very custom, boring enterprise stuff anyway).
Russia, on the other hand, has traditionally focused more on building its own products and brands, both for its domestic market (Yandex, VK) and the global market (Karsperky, ABBYY, JetBrains). When a technology they create for themselves turns out to be pretty good, it often spills over to the West and gains global popularity - examples being ClickHouse (originally to support metrics collection at Yandex), nginx (originally a reverse proxy at Rambler), etc. I have a hard time remembering something similar coming out of Ukraine?..
I may be wrong, it's just my impression of it (reading Ukrainian/Russian job postings etc.)
