Bottomless closes $4.5M Series A to scale its subscription coffee business Read full article March 3, 2021, 11:10 AM·5 min read As a devoted coffee drinker I was enthused by the idea of Bottomless. The Y Combinator-backed startup sends its users coffee as they run low so that they never run out of the Magic Juice of Life. What could be better? Because life is somewhat funny, after signing up for its service the company reached out to share that it had raised a Series A. So I got on the phone with Liana Herrera, the company's co-founder, to chat about the startup, which is part coffee-sourcing engine, part subscription/e-commerce play and part hardware effort.
