Startup Eight sleep, a company that develops sleep-improving products, announced it has raised $50 million to expand its operations.
The largest part of investments belongs to Tether Investments, which has currently reached a total of $250 million.
Founded in 2014, Eight Sleep aims to “deliver deeper sleep and better health.”
The line began with the Pod, a smart mattress with built-in sensors for collecting data and studying people’s sleep patterns. In 2018, the startup launched an AI-powered sleep consultant program that tracks sleep duration and categorizes sleep phases. Based on these statistics, the AI provides recommendations for when to fall asleep and wake up.
2025 was a landmark year for the organization, as Eight Sleep achieved positive free cash flow and launched three new products: the Pod 5, a Pod pillow case, and a thermal blanket.
«Sleep was just the beginning,» noted Eight Sleep co-founder and CEO Matteo Franceschetti. «We’ve built the world’s most advanced AI-powered health monitoring system that learns more about your body every night and acts on that knowledge.»
The investments we receive give us the resources to take our intellect beyond the bedroom and into all aspects of our personal health…
Last October, Eight Sleep experienced a rather unfortunate situation when its mattress accessories stopped working due to an AWS cloud platform outage and an inability to connect to the servers. This resulted in the beds overheating, forcing the company to add a «kill switch» feature to its products to address similar situations.
