"When Spiegel travels between his company's scattered outposts, he normally has a Range Rover with a private driver transport him from building to building. The former employee described it like the president arriving: a black car would pull up and Spiegel would hurriedly pop out with his security detail."
Johnny Depp spends "Over $150,000/month on full-time security for his children" according to current revelations. So $900K/year for someone who's not very famous isn't unreasonable I suppose.
It's easy to work out the cost of full time security. Lets say you need 2 people on rotation, they do 12 hours per day each (doable because they get to relax while client is at home etc.) then multiply by a reasonable salary for skilled labor like 70k then you get to 140k per year per person easily.
Lots of Venice Beach locals are not happy that Snap is buying up prime property / increasing rents / bringing in yuppies etc. I wouldn't be surprised if he's received threats and is most focused on security while in and around the office.
If Snap Inc. IPOs at their expected 25B value, Spiegel will be valued at nearly 5 billion (21% ownership), so ~1 million in security per year is not too far-fetched.
