The Signal is a fairly new part of my Substack where I share the early-stage companies, technologies, and movements shaping the future of health, detoxification, longevity, regeneration, and human potential — through my lens as a practitioner, health and detox expert, and active angel investor.
The future of health is for everyone.
I was at the Function Health investor event (beautifully named The Function Function) several weeks ago, and the momentum is absolutely undeniable.
50 million+ lab tests completed across members
$298M Series B at a $2.5B valuation
New pricing: $365/year — literally $1 per day (down from $499)
Function AI now live on web + app (I’ve tried it, and it’s so epic!)
Launch of the Medical Intelligence Lab — a doctor-trained generative AI model built to deliver personalized, actionable health insights
One thing the team emphasized really stuck with me:
We’re living in a world where people generate more health data than ever, like labs, wearables, scans, doctor’s notes…
yet most of it sits unused or disconnected.
Function Health is fixing that.
As TechCrunch put it, “the amount of health information people generate is accelerating rapidly… yet many struggle to connect this trove of data in a meaningful way.”
Function Health‘s answer is to consolidate it, interpret it, and make it usable through AI that’s built and trained by doctors.
Here’s my take:
This is the direction healthcare has to go — away from reactive sick care and toward proactive, preventive, personalized care powered by data, intelligent interpretation, and real behavior change.
Data alone isn’t the solution, but it’s the roadmap.
And, when people understand their biology, they can finally take targeted action, whether through detoxification, nutrition, or lifestyle.
And, this part matters:
Function Health’s Medical Intelligence Lab is being led by Dr. Dan Sodickson (chief medical scientist) and Dr. Mark Hyman, MD (co-founder & chief medical officer), alongside a full team of doctors, researchers, and engineers, ensuring the model is both medically rigorous and clinically relevant.
This is what it looks like when a mission-driven company scales with integrity — not just tracking data, but transforming it into real healthcare decisions members can act on.
And this is exactly why I invested.
My thesis is simple: the future of health lives at the intersection of diagnostics, prevention, and doctor-trained AI, giving people the clarity they need to take meaningful action through nutrition, detoxification, and lifestyle. Function is leading that shift with purpose, clarity, and conviction.
This raise is also a massive signal for founders:
Prevention isn’t fringe.
Integrated data isn’t optional.
AI-driven interpretation is becoming the new standard.
Huge congratulations to Jonathan Swerdlin, Mark Hyman, MD, Pranitha Patil, and the rest of the Function Health team for building one of the most important companies in diagnostics, prevention, longevity, and human potential.
This raise is a testament to the category they’re leading.
I’m genuinely proud to be an angel investor and early believer.
I’ll continue to break down more of these macro shifts inside The Signal, my Substack series on the future of health, wellness, and human potential. Make sure you’re subscribed to my Substack below for more.
Give The Gift Of Function
Every holiday season, especially after being inundated with endless Black Friday sales, we gift people things they don’t need:
sweaters and scarves that sit in closets, gadgets that get used once and thrown away, candles that disappear in a week.
But, this is a gift that actually matters.
A year of deep clarity.
A year of data.
A year of understanding your biology instead of guessing.
A year of empowering someone you love to take their health into their own hands.
Function Health is, genuinely, the most meaningful gift you can give another person.
For $1/day, you can give someone insight into their hormones, metabolism, cardiovascular markers, inflammation, toxic load, nutrient status, immune function — all the things that actually shape how they feel, age, heal, and live.
If Function Health has impacted you (or someone you love), this is the moment to share it.
I’m gifting it to people I love this year, too.
You may even want to gift it to yourself ;)
If you’re building the next generation of health, wellness, longevity, or human potential companies, send your deck through the deal flow form. I’m always looking for founders re-writing the future of human health.

Ready to finally resolve the root cause of your stubborn health issues when every other protocol has failed?
I’ll be teaching this work in a free 60-minute live masterclass on Friday, January 9, 2026, exploring what it actually means to heal from within and how deep, full-spectrum detoxification creates lasting change.
Take my free Detox Phase Quiz to uncover your physical symptoms you’re currently experiencing and to find out where to start your cleansing journey based on your body’s current needs.
Then, explore The Cleanses — a series of powerful digital cleanses that will guide you through a transformative detox journey towards optimal health and vitality, step by step. Whether you’re a total beginner or feel ready for deeper cleansing, these programs are designed to help you feel like your radiant, vibrant self again. We’ll be embarking on another collective journey in January 2026.
If you’re ready for a deeply personalized, high-touch experience, I currently have spots open for new VIP coaching clients in January 2026. This is a highly personalized, deeply supportive, full-spectrum transformative container for high-performing leaders, founders, CEOs, and entrepreneurs ready to reset their gut, balance their hormones, repair their metabolism, clear their skin, and reclaim their energy and vitality from the inside out through deep cellular cleansing and detoxification.
Want to know what it’s like to work with me? Read 50+ client testimonials and see for yourself. I’d love to connect with you.
Lastly, I’ll be opening up a 3-Month VIP Detox Mentorship in late January 2026 — a 12-week, small-group, strategic detox journey designed to reset your gut, rebalance your hormones, calm your inflammation, clear your skin, stabilize your blood sugar, and restore your natural energy and vitality so that you can reclaim your most radiant, vibrant self.
This will be a high-touch, high-support group container for deeper colon, liver, lymphatic, and deep cellular cleansing and detoxification with personalized protocols, bi-weekly (live and recorded) coaching sessions, and daily support and accountability, all in an intimate group setting with aligned individuals moving through the work together.
If this resonates and you’d like to stay in the loop as I share more in early January, you can quietly raise your hand here. Alternatively, reply to this email or comment below to share your thoughts.
Really fascinated by the business and your take on it. Thanks for sharing! And curious if you can explain more about scaling with integrity and what that means to you.
This is so exciting!! I work in integrative medicine in complex chronic disease and all of our patients went to multiple multiple specialists before receiving any diagnosis. This is going to completely change not only for prevention, but also for complex cases!
