Eight Sleep is the first sleep fitness company. At Eight Sleep we design products at the forefront of sleep innovation. Our mission is to fuel human potential through optimal sleep.

Backed by leading Silicon Valley investors including Founders Fund, Khosla Ventures and Y Combinator, we’ve raised 68 million to date. We were recognized as one of Fast Company’s Most Innovative Companies in Consumer Electronics in 2018.
Our temperature-regulated smart bed, the Pod is an absolute game changer, improving people's health and happiness by changing the way they sleep. It was named one of Time Magazine’s Best Inventions of 2019. We’re excited by the recognition and still have a long way to go toward achieving our mission.

An Insider's view of Eight Sleep

What's something quirky about your company?

Well we have actual beds in the office. Not nap pods, not lounge chairs, but actual bonafide beds. Getting pulled into "testing" in the middle of the work day really helps when the after-lunch slowdown hits. Even though it's a bit unusual to catch up with your CEO about the product while laying in bed, it can be surprisingly productive!

Andriy

Product Manager

What's the biggest problem your team is solving?

On the software team, we've recently been working on a "solo sleeper" mode. This mode allows the dual-zone temperature control and biometric sensing to be used across the full length of the bed. "Solo sleeper" mode is our most-requested feature, so it's been exciting to work on a problem that will solve our biggest user need.

Mercer

Software Engineer

What are some things you learned at the company?

Eight Sleep is my first startup experience. In the past I've worked in large companies where processes are regimented and systems are in order. I have learned not to take those things for granted while discovering the true meaning of rolling my sleeves up and getting my hands dirty. It’s enriching. It’s empowering.

Irish

Director of Accounting & Finance

How do your team's ideas influence the company's direction?

Every one of our team members uses our products and we encourage sharing feedback. We have a daily stand up that is open to the whole team. There we give a rating to features in beta, we share feature ideas, and we talk about issues being flagged by our members. We've had great ideas emerge from this meeting that are now part of our products.

Alexandra

Co-Founder, VP Marketing & Branding

What is your vision for the company?

We are using innovation and technology to make the world sleep fit. In ten years from now, most people will be sleeping in smart beds like the Pod, giving them a full night of recovery, ensuring they can be their best during their waking hours.

Co-Founder, CEO
