Wall Street versus Sillicon Valley

Dear all,

I am about to  intern with a financial analyst, though I really do not have any knowledge on finance but I really think I do have passion for this and it's something I can fall in love with.

Now here is my problem, my tutor just gave me a question which I am really confused about and would really appreciate everyone input on this.

"The idea here is about entrants into the Wall Street space need to mirror the market leaders. Wall Street doesn't "let" Silicon Valley companies come and play, and there is a reason. They try to be too disruptive (who moved my cheese). Therefore, there is a strategy being used by larger tech companies to mirror the org of their Wall Street brethren. Wall Street will know tech companies are either too risky, full of shit, or too disruptive to the fabric of the establishment if they dont have an org that looks and feels like Wall Street orgs.
- Define the organization structure with titles and names, reporting structure (if available)
for the following:
** Goldman Sachs, Blackrock, Blackstone, Apollo, Citadel Securities, JP Morgan,
TPG, KKR
** CAIS, iCapital

Highlight what you believe to be the most critical roles and what a WS company from a hedge fund, bank, to PE would be looking for in a company to enter their market."

Would really appreciate everyone input
