The Seattle startup using technology to make sure that coffee lovers never run out of the stuff they love has raised $1.9 million, according to a recent . The company declined to reveal investors. RELATED: Michael Mayer, the entrepreneur who co-founded Bottomless alongside his wife Liana Herrera, had been bootstrapping the 3-year-old company prior to raising $245,000 last summer. Bottomless combines original hardware, an online marketplace, machine learning and more to determine when customers need a shipment of fresh beans. The solution, in part, is a rechargeable scale on which users set a bag of fresh beans that they’re using to make their daily coffee. The scale is connected to WiFi (and to Bottomless) and as the bag becomes lighter, it triggers the order for more beans. Users select from numerous Seattle-area roasters — Caffe Vita, Ladro Roasting and more — who are partnering with Bottomless. Mayer, a “self-taught developer/technologist,” said his machine learning algorithms have already matured and that the plan with the new capital is to “add a few team members to continue investing in our algorithms and tech.” He also wants to scale up in the fresh coffee market with eyes on expansion, and they just added roasters in the San Francisco Bay Area and San Diego.
