Beth Kowitt, reporting for Fortune: Juicero has run out of juice. The San Francisco-based maker of counter-top cold-press juicers said today that it is shutting down operations and suspending the sale of its presses and produce packs immediately. The announcement on the company's website comes after the startup said in July that it was undergoing a "strategic shift" to more quickly lower the cost of its $399 juicers and $5-7 juice packs filled with raw fruits and vegetables. As part of the shift, the company said then that it would lay off about a quarter of its staff. At the time, Juicero CEO Jeff Dunn wrote in a letter to employees obtained by Fortune that the current prices were "not a realistic way for us to fulfill our mission at the scale to which we aspire." But Juicero realized it couldn't bring down the cost of its products as a standalone company. It was too small to achieve the required economies of scale on its own. The company will now focus on finding a buyer, it wrote in Friday's blog post. From an article in April: After the product hit the market, some investors were surprised to discover a much cheaper alternative: You can squeeze the Juicero bags with your bare hands.
