You can only apply for a fresh H1B once a year around April. It's a lottery with less than 30% chance of getting it. If a tech company wants to bring a European employee to the US they would have to wait until April, apply and if selected start work in October. It's a lot of time and uncertainty so they don't do it unless you're already working in their EU office and come over on L1 or something. Most H1B sponsorship is done for people already in the US on student visas (F1 OPT) or a transfer of an existing H1B visa that's been already through the lottery. Your best bet would be to try for an O1 visa but they have their own set of odd requirements.
