Reads like a recruitment piece for programmers, or maybe that&#x27;s how I read too many articles being programmer. I was a little confused by this:<p>&gt; For example, Jane Street, which is privately held, has increased its shareholder’s equity, or net worth, to more than $1 billion today from $228 million in 2007.<p>Is this supposed to be an impressive stat? ZocDoc has become about $2 billion company in basically the same time frame, which seems more impressive given that ZocDoc didn&#x27;t start from that $228M handicap. My perception is that it&#x27;s also much more expensive to run a company like Jane Street.
