The data seems to come from Dealroom (https://knowledge.dealroom.co/knowledge/how-dealroom-collects-data https://knowledge.dealroom.co/knowledge/how-dealroom-collect...), so with a bit of work maybe! It's pretty easy to look up similar companies in different countries, so it's clearly not manually collected data.
