Its Jetbrains, and they don't deny having workers there at all (the company itself If I recall correctly is located in the Czech Republic). In fact, they went through great expense to exfiltrate their Ukrainian employees and cut Russia off before everyone else got on the bandwagon (IE, before it was 'cool').

Like wich exactly? Jetbrains is one, but it is from Czechia IIRC. I was asking what tech products has Ukrainian tech sector produced.
