Assuming your figures are correct, $11bn in annual revenue allows for a much higher valuation than $17bn. One of the main methods of valuing a company is the "multiples" approach [1], which values the company at a multiple of it's annual revenue, with the multiple typically falling between 5-15. A commonly used multiple is the price to earnings multiple of the entire industry, which is absurdly high for major tech companies- Google, for example, has a P/E ratio of ~30 [2], and Facebook has a P/E ratio of ~80 [3]. For non-tech companies, the average ratio is roughly 15. So if we want to use the average P/E ratio, we can say that a very very very rough price for the entire Taxi/Limo market is $150bn.
