AI might ship your PRs but it won’t pedal your bicycle (yet). But why would you let it? ! Top-o-Tam is stunning…

I spent $1,000+ testing 5 blood biomarker services from @function @superpower @ouraring @UltrahumanHQ, and @WHOOP
Then I asked all 5 the same question: "My ApoB is elevated. What should I do about it?"
The results were revealing…

A few years ago, calling yourself a consumer health company in front of VCs was a virtual death sentence... but now, not only is consumer health being taken seriously, there are also some very serious consumer health businesses being built in the wild. This, plus other hot takes from @hollsmaloney, @ryu_alison, @KGSeidensticker and I at the inaugural Stanford Consumer Health Summit:
⚡ It's certainly possible now to build a large business purely based on cash pay + DTC acquisition. But playing nice with "The System" (e.g. B2B2C distribution, referrals from trad providers, taking reimbursement risk) still has its merits in helping one achieve even more durable scale and unit economics.
⚡ Sequencing of GTM motions matters: if you go "B2C first", you have the gifts of being able to fully control your product roadmap and swiftly acquire users - but it will be more expensive and potentially take longer to acquire them on your own. Going "B2B2C first" means you'll get access to large chunks of users in one fell swoop, but you'll have to pay a "product tax" to appease your B2B partner's requirements, not to mention needing to survive through long enterprise sales cycles. This sequencing choice informs your capital raising strategy in the early days.
⚡ A year ago, everyone was scared to say "AI Doctor", and now everyone is claiming to be building an "AI Doctor"!
⚡ To that end, will healthcare be dominated by an AI Doctor SuperApp as the front door, or will we continue to have fragmentation of apps by use case / condition / demographic? A large portion of consumers who don't have a PCP will find one in the form of an AI Doctor, and the best AI Doctors WILL be SuperApps that connect into a network of specialists and IRL clinical services through a single front door.
⚡ This necessitates a SuperData layer that allows for context sharing across all apps - and not just trad EHR data, but also wearables, genomics, non-traditional biomarker tests, information gleaned through ongoing engagement with AIs, patient-reported outcomes, health plan benefit design data info, etc.
The buzz in the room felt a lot like the early versions of the Health 2.0 conference in the late 2000's, BUT with companies that are really working and scaling this time around. Congrats to @ZHTeiger and his organizing team for bringing this community together - it's time to build in consumer health!

After taking a small break from Fitbit and Google, I’m starting something new and very personal.
As a co-founder of Fitbit, I thought I understood health tech. Caring for my parents from afar changed that perception.Trying to help manage their care was frustrating. Their data was all across portals, apps attachments, texts, and paper. I was constantly surprised at changes in their condition, unexpected dr visits, or other events. I looked for tools to help.
And I realized health tech for the family has a long way to go. This experience is a big reason that I, along with my Fitbit co-founder, Eric, are announcing Luffu (“loo-foo”) @weluffu
We’re building something I want for my family and your family. Software now and hardware in the future, weaved together in an intelligent family care system that gives families peace of mind. Join our waitlist: luffu.com

Claude Cowork just KILLED manual outreach.
I used to grind for hours on LinkedIn.
Now? My AI stack does it better.
- No "Hey {{first_name}}" spam
- Natural, multi-step conversations
- 12+ hours saved this week
The result: 500+ conversations with human-level reply rates.
I packaged the entire system (prompts + workflow) into a FREE doc.
Want it?

This is what building companies is all about. Well said @hnshah

Most people have no idea what it actually takes to be a founder. They talk about vision, grit, or passion. Those words are props. What you really sign up for is a life where every decision feels like it costs something real. You will spend years being misunderstood. By your team, your family, even the people you hire to help you. You will fail in public and still need to keep the energy up in private. Every founder lives with the weight of knowing that you can do everything right and still get crushed by luck, timing, or somebody else’s mistake. Founders aren’t braver than anyone else. They just get used to uncertainty, then stop waiting for clarity. Most of your wins won’t feel like wins at all. The first revenue will be too small. The first team will outgrow you or leave. The first product that feels right will barely matter to the market. You will doubt yourself in private, sometimes every week. The founders who last figure out how to keep moving while the ground shifts underneath them. Most outsiders want the founder badge but none of the scars. They want the upside, not the drag. The hardest part is sticking around after every plan gets blown up and you have to rebuild with less optimism and more scar tissue. What makes it work isn’t relentless hustle or some mythical trait. It’s learning to make peace with constant discomfort, and then making decisions anyway. If you need constant reassurance, you’ll give up before the real work begins. If you want everyone to like you, you’ll never make the calls that matter. If you can’t handle months where nothing feels certain, this life will eat you alive. But if you can hold your own in chaos, get better at being wrong, and still want to show up and try again, you just might have a shot at building something that matters. That’s what it actually takes. And nobody cares until you make it work.

Big Pharma makes billions selling statins & BP drugs to women.
But they don’t tell you that these drugs deplete a vital molecule your body needs—for energy, heart health & fertility.
It’s Coenzyme Q10 (CoQ10). Here's what they aren't revealing:

LAUNCHING TODAY: WHOOP ADVANCED LABS
Many people only get bloodwork once a year. You receive a sheet of numbers, maybe a “you’re normal,” and that’s it. No context. No coaching. No understanding of how to move from acceptable to truly optimal.
With WHOOP Advanced Labs, we’re changing that. Starting today, members can unlock two powerful ways to bring their blood biomarkers into the WHOOP experience:
1) Upload past bloodwork. Centralize your results from any lab, connect them with your 24/7 WHOOP data, and track long-term trends over time. This is included in all membership tiers for all WHOOP members and it will meaningfully improve the insights you get from all your data.
2) Book comprehensive testing. Through WHOOP, our U.S. members can now schedule curated blood panels that test 65 of the most impactful biomarkers, reviewed by a licensed clinician and seamlessly integrated into your app
From there, WHOOP goes beyond a static PDF:
-Context, not just numbers: With WHOOP, your bloodwork is no longer isolated. It’s integrated directly alongside your daily behaviors like sleep, recovery, training, and lifestyle choices.
-From acceptable to optimal: Every result comes with clinician-reviewed insights that explain where you stand today and how you can actively improve each metric over time. When you fall out of range on a metric, we will coach you to not just get back in range but actually reach an optimal level for your gender and age.
-AI-powered coaching: Our platform continuously analyzes your data and delivers personalized guidance, turning snapshots of lab results into a living feedback loop that makes your health dynamic rather than episodic. We’ve made significant investments in our A.I. infrastructure in the last six months, and you’ll see the benefits as your data comes together. Tell WHOOP what supplements you take, upload your blood tests, and await as the feedback gets much more useful.
WHOOP Advanced Labs is more than a new feature. It’s a building block of a new Health Operating System that we’re building at WHOOP: a future where your body is continuously monitored across hundreds of dimensions, where feedback loops between biology and behavior are surfaced in real time, and where AI helps you take proactive steps to live longer, healthier lives.
Already, more than 350,000 members joined the waitlist for WHOOP Advanced Labs. Today, the first members are gaining access in the U.S., with a global rollout to follow. Enjoy!

@drink_AG1 launched their long-awaited AGZ Sleep product.
I was thrilled to learn AG1 opted for a similar formulation as @elo_health Sleep Gummies. The two major differences are
1️⃣ AGZ's lack of Melatonin
2️⃣ AGZ's $30/mo higher price
