Let's build a list of tech influencers in different cities/countries

Hello hackers, I was planning an event in Copenhagen recently and thought to connect with local tech influencers to promote it.

I was looking for people/organizations who have the attention of Founders, CEO, CTO, Product managers, Engineering managers - those who manage remote developers.

The search wasn't successful. Maybe there is a service for this problem?

Let's build a list here, it could be useful for the entire community.

Please, mention accounts and their location here.
