Keith Krach is worth at least $1.8B.
Not certain how much of his DocuSign stock he retained when he took on the Undersecretary of State role. I recall reading his own comments during the fantastic rise in DOCU stock last spring and summer that gave the impression that he had liquidated his holdings in order to avoid real and perceived conflicts of interest with his admirable public service role [in which, in my judgment, he was extremely effective!].
That said, Keith is, as the saying goes, fabulously wealthy, as are many other alumni, many of whom who fly under the radar as was previously noted. Holding wealth via corporations to conceal the ownership's identity is quite common.
I have a friend whose name should appear on the Forbes 400 list of wealthiest Americans -- certainly in the top 100 and probably in the top 50. His holdings are mostly in private companies, so he is somewhat invisible to the media and others who track such things.
It very well could be that there are a number of Purdue alumni who are generally unknown to the public whose wealth far outstrips some of the folks mentioned in this thread.
This is a fun topic for me as it is one category of success for Purdue alumni along with accomplished alumni in their respective fields where dollars are not the unit of measure that makes me so proud to be a Boilermaker!
Ever Grateful, Ever True!
