There are 10 employees with 140k salaries at my company and 5 with 150k but none with 139k or 147.26k. People like round numbers, especially when you consider significant figures and how speculative the valuations are. Airbnb could realistically be with anywhere from 500 million to 30 billion or more. The current valuation is a largely bullshit arbitrary number that VC and founder agreed to for God knows why in their latest negotiations. In these negotions you don't counter for 5 or 10% more. That isn't within the significant range.
