Inflation adjustments gets pretty fuzzy even in the same nation across a few decades, let alone between different nations across centuries.
The article equates the 1637 peak valuation of 78 million guilders with current day 7,900,000 million dollars (not the 79,000 million according to the bad math in the article!). Now consider that the initial capital raised for the company was 6.4 million guilders in 1602. That would be around 600 billion USD. (I'm neglecting inflation between 1602 and 1637 here, that doesn't change my point.) This was raised around 1800 families, with share varying from 50 to 85,000 guilders, which according to the implied inflation/currency conversion is between 5 million and 8.6 billion USD. How credible is is this conversion factor?
Consider as another reference that the nominal value increased 12 fold over 35 years. Todays elite PE/VC/incubators would probably scoff at such low ambitions. (Though the East India Co was pretty profitable and paid handsome dividends, so the returns are higher than capital gains.)
