Soylent? No normal person I have ever met in my life has ever heard of the stuff. Slim Fast — everyone has heard of that, but Soylent? That’s an ultra niche product with little mass market appeal. Is it successful? Sure, but about as successful as a company that produces kits for growing orchids. The whole concept of Soylent is essentually Ensure for Hipsters. Even the name sounds like some kind of cyberpunk cliché.
