Very strange and arbitrary selection of cities for Europe, it seems. How were the 29 selected? What often happens for these kind of lists is people assume those reviewed are somehow better than those left out. Hope this will clarified once the report gets published, that many top location were just left out.
So I'll just say quickly:
1. Tallinn and #estonianmafia (3 500Startups investments, 6 Seedcamp investments)
2. Helsinki and the world's leading gaming scene.
Also: if you want to make the review serious, decide on the cities based on statistics. As Seedcamp for Europe, which are their top cities for their investment winners. Don't shoot from the hip.
