@anothercohen Greetings from Eight Sleep R&D! If you are willing, we'd be happy to hear your feedback on the sleep score and sleep metrics. My DM is open. Thanks!
Today we are launching Autopilot 4.0, a new generation of Autopilot that acts as a sleep agent.
Autopilot 4.0 uses data from your day and night to predict how you’re likely to sleep, automatically adjust your sleep environment through the Pod, and explain what happened by morning in plain language.
This is the next step in what makes Eight Sleep different.
We do not just surface data or generate sleep insights. We use that data to actively respond through the sleep environment itself.
Members can connect Apple Health or Health Connect, or tag events directly in the app, giving the sleep agent more context from workouts, activity, stress, alcohol, meals, and other daily inputs. That context helps it predict what may happen during the night and make the right adjustments before and throughout sleep.
Autopilot 4.0 is built on more than one billion hours of sleep data and is now available in the Eight Sleep app.
We've been named one of @FastCompany's Most Innovative Companies of 2026. This is our fourth year on the list.
When we founded the company, no one believed your time in bed could meaningfully change your health. The night was the most underutilized lever in human performance — and we set out to change that.
Ten years later, the Pod doesn't just track your sleep. It reads what's coming and adjusts before disruption hits, reducing menopausal hot flashes, helping you fall deeper into sleep, and cutting the time you spend lying awake. Built on over a billion hours of real sleep data across 34 countries. A dataset no other company has.
This year: a $1.5B valuation, peer-reviewed research proving we restore the body's natural circadian rhythm during sleep, and an FDA filing for sleep apnea detection.
We are not building a better sleep tracker. We are building the defining health technology company of this generation.
This recognition belongs to everyone who bet on sleep before it was obvious — our team, our athletes, our members.
The future of health starts tonight.
A month of engineering work compressed into 2 days. That's what we shipped for World Sleep Day.
We curated a team of 21 agents covering data engineering, biostatistics, public health, visual design, and even data governance and ethics in the context of GDPR. With a structured generative process, every single insight is grounded in real-world data and fact-checked against the query and statistical tests. A style-guided generative layer renders the final output in the @eightsleep design language.
A project like this used to mean a month of engineering and months of timeline. We shipped it in 2 days with 6 major version changes, and cross-functional feedback turned around in minutes.

World Sleep Day. We're marking it the best way we know how: with data.
We just released https://t.co/wj0FotCsjN. 10.2 million nights from 23 countries. One year of continuous measurement.
Some findings confirmed what we expected. Others didn't.
- REM sleep peaks in your 40s then drops sharply
- Men lose 0.71% of deep sleep every decade. Women stay flat
- HRV drops 43% from your 20s to your 60s
- Super Bowl night HRV dropped 4.8%. Bedtimes barely moved. It wasn't the late night. It was the alcohol.
Today, I’m excited to announce our partnership with @AstonMartinF1. Growing up as a motorsport fan and a racing car driver myself, I’ve always admired the precision and dedication that goes into every race.
When I first connected with the Aston Martin team, it was clear they shared our vision at @eightsleep.
This isn’t just a logo partnership. @AstonMartinF1 is now an investor in Eight Sleep, because they want to integrate our technology directly into their performance strategy.
Aston Martin has been quietly building toward something. So have we.
We’ve built something new, internally called FirstLight.
It uses state-of-the-art deep learning trained on million+ nights of high-fidelity sleep and health data, combined with ambient context, to predict the most comfortable temperature profile for new members from their very first nights.
Think of it as a head start for Autopilot. Truly personalized recommendations from day one.
It’s live to all new members.
This one is for couples who’ve been entangled in blanket wars for years. For women whose bodies spike and shift with cycles, pregnancy, and menopause.
This one’s about so much more than the science, the metrics, and the engineering.
This one’s about waking up and loving how you feel.
So tell us, how do you love it?
Guess the NFL team heading to the AFC Championship, using the Pod to power their performance.
Last weekend, our team installed 50+ Pods in their hotel in under 24 hours.
We're ready to support them all the way to winning the Super Bowl!
San Francisco for a day. Beautiful and soooo interesting visiting my friends at Eight Sleep and visiting Apple for the first time.
Now, time for Vegassssss @vistajet ❤️
90+ hours. 4 intense days. One mission: Go beyond 99% accuracy.
Our clinical team just wrapped a deep round of human testing, validating new sensing algorithms and improvements, ensuring all of our biometric data meets our high accuracy standards.
Every signal we ship is tested for precision, reliability, and real-world performance.
That’s how @eightsleep builds and validates.
I’ve long believed sleep should be more than rest.
We are developing new sensing technology to continuously assess arterial stiffness while you sleep, no wearables required.
Your bed won’t just restore your body. It will monitor your long-term cardiovascular health and alert you of abnormal conditions.
We are A/B testing the world’s first foundation model on bed sensing that will drive the next phase of our ML models.
Instead of using multiple models, this SINGLE machine learning model unleashes embeddings of heartbeats, breathing, movements, and even things we haven’t thought of.
Why it matters:
1️⃣ Higher-resolution health insights
2️⃣ Better biometric accuracy
3️⃣ A system that learns and improves with new user data
This will further elevate the accuracy and sophistication of our products.
