$4.5B Valuation for an SaaS business that doesn't charge for it's service and makes money from commissions? Did they invent something no one else can do? Why would insurance companies not just scrap the middle man and build their own thing?
In fairness, this is also a rough description of the business model of ebay (current market cap: 70.2B). Like Zenefits probably eventually will, ebay has added various bolt-on services, but its core business has always been, as far as I can tell, making commissions on transactions between others. See also: AirBnB.

It's not so much that the underlying technology is that mind blowing (it isn't, or at least, historically hasn't been). Indeed, I'm hoping they invest some reasonable chunk of this cash in improving ui/ux. But execution matters, and the mere fact that, like facebook, they didn't really "invent something no one else can do", doesn't mean they aren't creating a hell of a lot of value.
I don't know Zenefits' market or business well enough to have any idea whether $4.5B is reasonable at their current stage, but it's not beyond the realm of possibility.
