"What we're building doesn't exist yet - a system that understands your body better each night and acts on that knowledge. Our goal is to build the defining health technology company of this generation. The company said that it wants to work on a sleep-focused AI agent that controls the temperature, elevation and firmness of its products proactively and prevents sleep disruption."

"Eight Sleep said it was free-cash-flow positive in 2025, and plans to use the new funding for new products, global expansions, and clinical validation. The company currently ships its products to over 34 countries. The company said it wants to expand beyond selling consumer products, and has sought approval from the U.S. Food and Drug Administration for products that can detect and mitigate sleep apnea."

"Eight Sleep said that its models are trained on proprietary data, and early pilots of its AI-driven guidance have resulted in people changing their habits, such as exercise timing, caffeine intake or sleep schedules, based on the analysis provided by the app."
