There are rare moments in tech when you use a product for the first time and it feels like magic.
- Tap a button. A cab shows up.
- Type an address. A blue line takes you there.
- Tap your phone. Payment is complete.
- Put an earbud on. The audio connects and follows you.
This reminds me of one of those moments. Tap. Whisper a thought. It's saved, even actioned on.
Temple is an ambitious project. The team is delusional enough to think we can build this. And we will.
Here's what we are building. Join the ride.

Critics risk very little compared to those who put their work out into the world.
If every breakthrough needed the approval of the loudest critics…humans would never make progress.
Just keep building 🚀
Dear Concerned Indian Doctors,
I see your rage against Temple on X. I have a few points
to make:
1. First and foremost, a business lesson: if Temple were a scam, and any of what we said weren't true, people would know it in just a few days of using Temple. We have 14-day, no-questions-asked returns (which even Apple doesn't offer in India). If the product doesn't work, it fails out of the gate and the company dies before recovering a tenth of its R&D.
2. We have already spent $30m building Temple, $20m out of which is my own money. Selling a few thousand devices recovers a small fraction of this investment. A scam that pays nothing is not a scam anyone would run.
3. I left the Eternal CEO role to chase purpose with Temple. This is not about money. I have enough of it to last for generations. My incentives are fully aligned with getting the science right. I am not staking a reputation earned over 20 years on making a quick buck.
4. Our employees bought into our round a few months ago. The round we're raising now is mostly our customers. Scams don't build that cap table.
5. Most wearable companies start with internal studies. Whoop shipped its band in 2015, and the first published validation followed a few years later. We hold ourselves to a higher standard; pre-prints are a step prior to peer reviewed publications, and they are coming up.
6. At some point you have to stick your neck out and say: we believe in our science, and the product is now valuable enough for people to pay for and use. We believe we are there. More validation continues in public.
7. We are confident that we are building something that the world is going to be positively astonished with. We stand by our science and our methods. Each of our claims is easily verifiable by individuals and institutions alike, and you will see a lot of independent studies come up on their own when the device becomes available to use.
Last but not the least, the most ground breaking features in Temple are not even public yet. And some of them, thankfully, have nothing to do with doctors 🤭
Hope this addresses some or all of your concerns. If not, keep raging 😘🤗

How do you tell the difference between a cramp and something your body is trying to tell you?
If your legs feel restless, not painful, not cramping, but an urge to move that eases the second you get up, especially at night, that’s not random.
It’s a recognized pattern.

Struggling to feel rested? A sleep study can uncover the reason and the treatment path. Don’t sleep on it. Most people who need a sleep study never get one.

A rough week of stress-related sleep is common and usually resolves on its own. But there's a point where self-managing stops being the right move.
If you think you have insomnia, speak to your doctor or physician.

If there's one sleep biohack actually worth the label, it's not a supplement or a device.
It's your circadian rhythm.

The world's most effective peptide costs $0.
Sleep is when your body releases most of its growth hormone to repair tissue, consolidates the day's memories, resets your hunger and blood-sugar hormones, and clears metabolic waste from the brain. It is our best tool for health.

Temple's first validation study is out.
Researchers tested Temple's Brain Flow index head-to-head against Transcranial Doppler (TCD), the gold standard for measuring cerebrovascular function. 23 healthy adults, two challenges: cycling and a standing-to-supine postural shift.
The result that stood out most to me: when participants lay down, their heart rate dropped, but their brain blood flow went up. Temple tracked this accurately, right alongside the Doppler. Any device that only measures heart rate would have gotten this completely wrong.
Across both challenges, Temple's Brain Flow tracked Middle Cerebral Artery velocity (MCAv) with within-subject temporal correlation of r≈0.8 (p<0.001), which is very high even for medical devices.
The paper is posted as a preprint and submitted for peer review. One study, two interventions, healthy adults only, but it's the first step. More validations on Brain Flow, as well as on Entropy with different modalities are underway across the globe. We will keep sharing them as they trickle in.
We encourage researchers to replicate this. We'll happily loan Temples to any qualified researcher who wants to pressure-test any of our metrics independently.

$HIMS
🚨 SLEEP IS A NEAR TRILLION-DOLLAR INDUSTRY, PER HARVARD-TRAINED SLEEP DOCTOR @BREATHENSLEEPMD
"In the United States, there's about 30 million people who have obstructive sleep apnea. Globally, there's about a billion people who have sleep apnea."
"If you look at CPAP [sleep apnea] as a market, with people who have been diagnosed, it's about a $6 billion market today. It can maybe grow to maybe $30-40 billion over time."
"But if you look at sleep as the ENTIRE market, it's probably hundreds of billions, maybe close to a TRILLION dollar market."
"Sleep apnea / CPAP dispensing is like the smallest sliver of a very big market. It's the smallest business of a very big business that can be built."
@schopsss: "Right now, sleep sort of sits as its own specialty and its own category. But really, sleep should be sitting across the whole ecosystem of medical care."
"Sleep should be a part of every clinical workflow that exists. It should be in every primary care office, it should be in every cardiologist office, every psychiatrist office should be somehow approaching sleep."
🚨 AI-POWERED SLEEP CARE COULD BE A MASSIVE OPPORTUNITY FOR $HIMS
Today I'm joined by Sagar & Sahil Chopra --- founders of Empower Sleep, one of the leading telehealth sleep platforms in the world. @schopsss @BreatheNSleepMD
We discuss why traditional sleep care is broken, why single-night studies miss so much, how Empower combines medical-grade sensors with Oura / Whoop data, the economics of the industry, and how $HIMS could enter and succeed.
Huge thanks to Sagar & Sahil for joining the show!

Sleep is not sleep apnea.
Sleep apnea is not just CPAP.
CPAP is not the sleep market.
Sized correctly, sleep is one of the largest opportunities in healthcare nobody's pricing in.
It's not a separate "category." It's a horizontal layer that amplifies every other category if implemented correctly.
Grateful to the @himshouse community for the conversation. Huge thanks to @AndySalamon for the plug!

Sleep is massive. A few things are happening:
- aging customer segment into osa that’s cognizant of sleep health
- more screening via better sensors and wearables (this is huge)
- alternative therapies, other than cpap
The challenge with most sleep companies in the past is that they’ve indexed on cpap as the endpoint. The key is that cpap is just one of many therapies, and often not the one that works. Also, humans always need long-term monitoring and care (because so much of sleep is behavioral and physiology always evolves)
This is 100% correct. The right customer segment just needs to age into the OSA disease category, and we’re getting pretty close. 3-5 years this will explode.
@BreatheNSleepMD @schopsss are building that size company is my bet.
@AndrewDudum knows all about this area btw🤣
