Welcome to the 217th episode of the Inc. Uncensored podcast, hosted by Inc.'s editor in chief, James Ledbetter.

First, I break down the eye-catching news from Uber's long-anticipated IPO registration: According to its S-1 filing, the company may never be profitable. Plenty of money-losing companies succeed on the public market by showing investors viable paths to long-term profitability. But a business that readily admits it may never make money? We discuss the factors behind Uber's bold strategy.

Next, editor-at-large Burt Helm conducts a deep dive into his May cover story on Sweetgreen, the cult salad brand that's reinventing itself as a tech company. Sweetgreen has spent the past year hiring high-profile data scientists and other digital experts to develop "a quick-service restaurant reimagined in the spirit of an Apple store"--and raised $200 million to make it happen. It's an instructive tale for all entrepreneurs.

Finally, senior writer Christine Lagorio-Chafkin discusses the strange case of how Warby Parker touts its social mission. When the eyeglasses company first launched, it gained attention for its "buy a pair, give a pair" strategy. While Warby's core goals never changed, over the years that messaging disappeared from its marketing. As it turns out, there's a specific reason why.
