Eight Sleep Files for IPO Following $6M Seed Funding and Strong Market Traction in Personalized Sleep Tracking

Eight, a company specializing in sleep tracking services (formerly known as Luna), recently secured $6 million in seed funding. The round was led by Y Combinator, with participation from Yunqi Partners, Azure Capital, Cota Capital, Comcast Ventures, Vast Ventures, Stanford University, Galvanize Ventures, Idea Bulb VC, and Scribd founder Jared Friedman. Part of the funds will be used to fulfill existing pre-orders, while the remainder will support the development of new software features, such as personalized sleep training for users.


“The concept behind founding Eight actually stemmed from my own sleep issues,” said Matteo Franceschetti, Founder and CEO of Eight. “I struggled for years with poor sleep quality, trying various wearable devices and apps designed to track sleep in an effort to identify the causes of my disrupted sleep patterns and poor rest. Although these devices and apps offered a range of features, they failed to deliver any meaningful practical benefits. The problem was that they required being worn on the body, attached to the bed, or placed on the nightstand to function, yet still failed to provide accurate sleep-related data,” Franceschetti explained.

Consequently, he decided to design a device that meets individual sleep needs, providing personalized sleep tracking for each user. Thus, the smart mattress was born; when connected to its companion app, it can track users’ sleep patterns and thereby improve their sleep quality.

The product launched by Eight can track users’ daily bedtime, sleep onset time, wake-up time, and rising time, as well as body movements, heart rate, respiratory rate, and total sleep duration during sleep. It can also detect environmental factors that affect sleep, such as indoor temperature, humidity, light intensity, noise levels, and local weather changes. Notably user-friendly, this smart mattress features more than ten temperature regulation modes. When users share the bed with a partner, they can independently adjust the temperature on either side, allowing each individual to select their preferred sleeping temperature to ensure high-quality sleep.

Once this data is collected, the companion app analyzes it to provide users with a sleep quality score. Additionally, users receive insights into trends of sleep deprivation, their sleep depth, and other tracked time-related sleep metrics.

This smart mattress system, which tracks sleep, is priced between $249 and $289 depending on the mattress size, and can be pre-ordered on Eight’s official website.

Last January, Eight launched a crowdfunding campaign for its product, ultimately raising $1.2 million—far exceeding its initial target of $400,000—and demonstrating the company’s significant potential. Although the campaign concluded as early as March of last year and all orders have been fulfilled, Franceschetti stated that they are fully prepared to continue expanding their product and service offerings this spring.
