It would be great to use Wikidata for that. It's already possible to add a list of investors (https://www.wikidata.org/wiki/Property:P1951 https://www.wikidata.org/wiki/Property:P1951) to companies (like Uber: https://www.wikidata.org/wiki/Q780442 https://www.wikidata.org/wiki/Q780442). And then map all these startups using https://query.wikidata.org https://query.wikidata.org (it would be pretty easy to highlight the % of shares by countries / regimes, etc and point out the financial vehicles / intermediaries used for that).
