You are technically correct. Silicon Valley uses P/E when calculating valuation/revenue, because startups are rarely profitable.

They aren't equivalent in the same way that user growth and revenue growth are not equivalent to profit growth. A misinformed statistic for a misinformed view of how to build a successful business.

Valuation/revenue would be price/sales, or P/S if you will. The P/E is a "forward P/E", with P = "today's price" and E = "someone's expectation of next year's earnings".

I agree on what it actually is, mine was a comment on how it is used. I've seen P/E used many times in SV referring to valuation/revenue.
