Some napkin maths:

$3.8M seed round

a properly structured round usually costs (12-17%) so ~15% of the company

that means Dylan raised at a ~$25M valuation

$20B is 800x $25M

So, for every $10k this self-congratulatory cough gave his former intern after their walk, he just made $8M.

Not too shabby, regardless of any emotional context you may project.
