## About

Based in New York, US, Eight Sleep, Inc. formerly known as Morphy, Inc and Luna Sleep was founded in 2014 by co-founders Matteo Franceschetti, Alexandra Zatarain, and Massimo Andreasi Bassi. The company specializes in developing and manufacturing smart mattresses. Eight Sleep started with a crowdfunding effort that offered sleep monitors to 6,048 clients in over 50 countries. In October 2017, Eight Sleep, Inc. released the Alexa Skill smart mattress, which allows customers to communicate with their mattress and view their sleep data via the Echo and other Amazon devices. In March 2026, Eight Sleep, Inc. raised USD 50 million in series D funding led by Tether Ventures, with participation from Y Combinator, Founders Fund, Valor Equity Partners, and HSG. The company is a developer of an electronic mattress that manages bed temperature and tracks sleeping patterns to improve healthy sleeping habits using active grid technology and a pod thermometer alarm. The company's platform also offers blue wave glasses, ultimate pillow, waterproof protector, and foundation. The firm uses innovation, technology, and personal biometrics to return individuals to their optimum energy levels each morning, allowing consumers to regulate and measure their sleep. The company generates revenue by selling mattress that retails for nearly USD 3,000 for its smallest size, a queen, and a smart cover that starts at USD 1,720. The company plans to use the March 2026 funding to expand from sleep optimization into predictive, AI-driven health by building systems that anticipate recovery disruptions and advancing clinical and regulatory work such as FDA filings.
