A month ago, I shared how @GetTinyHealth started in my garage, with my mom hand-packing every kit.

Today, the next chapter: we’ve raised a $33M Series B led by @BCapitalGroup, bringing our total funding to $46M.

From newborns to centenarians, we’re building Tiny Health for you. ❤️

Gut health is so important! And that's what makes companies like this one so interesting...

Cheryl Sew Hoy (@cherylyeoh) started looking into the gut microbiome when her daughter developed eczema, allergies and food sensitivities. In 2020, she turned that curiosity into Tiny Health (@GetTinyHealth).

The Austin startup has raised a $33 million Series B round led by B Capital. What began with a test for babies has grown into a business serving adults, clinicians and other health companies. Tiny Health says it has collected nearly 200,000 microbiome samples, and its longer-term goal is to see whether that data can help identify health risks earlier.

I spoke with Sew Hoy about the company’s growth, its research plans and what the new funding will support.

Super interesting company and topic!

𝐖𝐞'𝐫𝐞 𝐥𝐚𝐮𝐧𝐜𝐡𝐢𝐧𝐠 @GetTinyHealth 𝐨𝐧 𝐓𝐨𝐮𝐫 - Gut Microbiome: The Next Frontier of Medicine.

Next Wednesday, our first stop is San Francisco.

A series of intimate gatherings, one city at a time, bringing together the researchers, clinicians, founders shaping the future of gut health.

At our inaugural SF event, Dr. @ElisaSongMD and I will be sharing something publicly for the very first time: 𝐎𝐮𝐫 𝐧𝐞𝐰 𝐢𝐧𝐟𝐥𝐚𝐦𝐦𝐚𝐠𝐢𝐧𝐠 𝐚𝐧𝐝 𝐠𝐮𝐭 𝐫𝐞𝐬𝐢𝐥𝐢𝐞𝐧𝐜𝐞 𝐦𝐚𝐫𝐤𝐞𝐫𝐬.

New science on the chronic, low-grade inflammation that quietly drives aging and disease, and what the gut microbiome has to do with it.

Speaking at the event with me:

• Dr. @EmeranMayerMD — UCLA professor, gut-brain researcher, bestselling author
• Dr. @DrRosenIBD — Director, Stanford Medicine's Pediatric IBD and Celiac Program
• @maxmarchione — Founder and CEO of @superpower
• Dr. Melina Jampolis MD — Physician Nutrition Specialist, 5x author
• ​Dr. @ElisaSongMD — CMO of Tiny Health and best-selling author

The evening will feature an expert panel discussing how microbiome testing is being integrated into clinical practice, biomarker applications, and emerging insights shaping the future of personalized care.

​This is an opportunity to exchange ideas, ask questions, and connect with peers who are passionate about advancing microbiome medicine. The room itself will be worth staying for. Professors from UCSF, executives from @midihealth, @thornehealth, @BuckInstitute, VCs in the longevity space, and a few others who don't need an introduction. More being added by the day.

A huge thank you to Max Marchione and the Superpower team for hosting us and helping bring this first City Tour event to life.

Looking forward to seeing familiar faces, meeting new ones, and kicking off what I hope becomes a special tradition for the Tiny Health community.

Space is limited and registration is by approval, so RSVP soon if you'd like to be considered. Link in the first comment.

𝘊𝘢𝘯𝘥𝘪𝘥𝘢 has a reputation problem.

64% of healthy people have it in their gut. It's causing no harm or reason to sound an alarm.

But the myths spread faster than the science. Bloating, brain fog, fatigue often get blamed on 𝘊𝘢𝘯𝘥𝘪𝘥𝘢, when the truth is almost everyone has some, and small amounts are normal. The real problem is what happens when the broader ecosystem loses its resilience.

𝘊𝘢𝘯𝘥𝘪𝘥𝘢 lives in the small intestine, but stool tests measure the large intestine. So a trace result on a PCR test isn't necessarily a sign of overgrowth, yet it's often enough to send people into harsh cleanses and antifungal protocols that can disrupt the very ecosystem meant to keep it in check.

But none of this is to say overgrowth isn't real. For some people, it may be a root cause behind exhausting chronic symptoms that haven't resolved any other way.

The good news is that healing doesn't have to mean isolating and attacking one organism. It can mean rebalancing the entire ecosystem so your body can naturally keep it in check again, helping resolve your symptoms now and support longevity down the line.

At @GetTinyHealth, we interpret 𝘊𝘢𝘯𝘥𝘪𝘥𝘢 in the context of the full gut ecosystem. Our stool test detects 𝘊𝘢𝘯𝘥𝘪𝘥𝘢 DNA alongside microbial diversity, beneficial bacteria, and inflammatory patterns. If you want an exact quantified level, our practitioners offer a qPCR add-on that measures it with high sensitivity. Either way, you're never looking at one organism in isolation.

We put together a full guide debunking the biggest 𝘊𝘢𝘯𝘥𝘪𝘥𝘢 myths, how to test for overgrowth at home, and ways to support gut balance naturally. Link in the first comment.

Have you ever done an aggressive gut protocol based on a single test result? What happened? Share it below.

@theA4LI

[Cheryl (Yeoh) Sew Hoy @cherylyeoh]

Kimberley Sukhum and I spent this week in DC, first at the H-SPAN summit, then on Capitol Hill as part of @theA4LI. The whole experience left me energized about where healthspan science and longevity policy are headed.

At the summit, one topic kept coming up: 𝐦𝐮𝐥𝐭𝐢-𝐨𝐦𝐢𝐜𝐬.

Instead of chasing a single biomarker, the future of healthspan lies in understanding how multiple biological systems drive the aging process.

It was great to hear how often the gut microbiome came up as a critical piece of that puzzle.

We were proud to represent @GetTinyHealth at the summit, where I joined a panel on measurable biomarkers and preventative health throughout the lifespan.

We heard presentations from leaders like Dr. @ISBLeeHood, inventor, and pioneer of systems biology and CIO of the Buck Institute, Dr. @DrOz, 17th Administrator of the Centers for Medicare & Medicaid Services, and Felipe Sierra, who led the NIH Division of Aging Biology for 14 years and popularized the concept of healthspan and geroscience.

One policy I came home focused on: 𝐑𝐢𝐠𝐡𝐭 𝐭𝐨 𝐓𝐫𝐲. Montana's SB 535 lets licensed clinics sell therapies that have only cleared Phase 1 safety trials. Patients opt in at their own risk, and doctors are shielded from liability. Huge credit to @dullunlivin and the team at A4LI for drafting the bill, and to @NiklasAnzinger and Stephen Martin for their work getting it passed.

It's the kind of framework more states should study closely, and Texas is well positioned to be a strong partner. Our healthcare systems, specialty-care tourism, and top-tier biotech ecosystem in Austin give us real advantages.

We're hopeful we can bring this model to Texas, learning from what Montana has already built.

From there, we headed to Capitol Hill, where the conversation shifted from scientific breakthroughs to the policies needed to accelerate them.

Staffers want to hear directly from the people doing the work. We talked about increasing NIH and federal funding toward longevity research, and shared how Tiny Health is innovating in gut microbiome health as part of the broader healthspan picture, and what policies could help accelerate that work.

A few years ago, this conversation would have been on the sidelines, but this week it was front and center. Now the opportunity is making sure our research priorities and regulatory frameworks evolve just as quickly as the science.

That means hearing from more than just the people in the room.

Next week, I'm bringing the gut microbiome to Washington, D.C.

I'm speaking at the H-SPAN Summit at Georgetown University on June 29th, hosted by @theA4LI – thank you to @dullunlivin for the invitation and for including me on this panel.

Longevity science, biotech leaders, policymakers, and advocates all in one room, pushing for legislation that supports a longer, healthier human lifespan.

I'll be representing @GetTinyHealth on the gut microbiome side, sharing the stage with @SlowMyAge, founder and CEO of @NovosLabs, and Jose Luis R. Andrade, co-founder of Deleon. Moderated by Gayland Hethcoat of @ArentFoxSchiff.

Dr. Kim Sukham and I will be at the VIP dinner Tuesday with fellow speakers like @alinaruisu of @GenerationLab_, Bobby Brooke of Intervene Immune, Reena Bhargava of BiotraxAI and more.

And on Wednesday we'll be meeting with federal and state reps on the Hill to discuss longevity policy.

A packed couple of days on the hilltop, and I couldn't be more proud to represent Tiny Health and gut health on the Capitol.

If you're working in longevity, policy, or preventive health, what questions or topics would you want me to bring into these conversations? Drop them below. 👇

3 weeks in Japan with 3 kids, including a 15-month-old, and a work schedule synced to US hours from the opposite time zone. 😅

My Oura sleep and stress scores are wrecked. I'm working until midnight most nights just to keep up, and the 15-month old is waking me every few hours on top of that.

Don’t get me wrong. The food is incredible, the culture is amazing, and our kids are having a ton of fun.

But I'll be honest, this trip has not given my body or my mind a break. It's made me rethink whether weeks-long international travel with a baby under 3 yrs is actually worth it. The jury's still out.

What I'm proud of is that despite the stress and change, none of us have gotten sick. I attribute that entirely to being deliberate about supplements.

What's kept me healthy:

𝗗𝗮𝗶𝗹𝘆 𝘀𝘂𝗽𝗽𝗼𝗿𝘁:

• Vitamin D
• Zinc
• Beekeepers Naturals immune support throat spray
• @morningwtr: creatine + electrolytes mix (code CHERYL for 10% off.)

𝗔𝘁 𝘁𝗵𝗲 𝗳𝗶𝗿𝘀𝘁 𝘀𝗶𝗴𝗻 𝗼𝗳 𝗮𝗻𝘆𝘁𝗵𝗶𝗻𝗴 (𝘀𝗼𝗿𝗲 𝘁𝗵𝗿𝗼𝗮𝘁, 𝗳𝗲𝘃𝗲𝗿𝗶𝘀𝗵, 𝗿𝘂𝗻𝗱𝗼𝘄𝗻):

• Lyposheric Vitamin C
• NAC
• Boiron Oscillococcinum or Cold Calm

𝗙𝗼𝗿 𝘁𝗵𝗲 𝗸𝗶𝗱𝘀:

• HerbPharm Kids Immune Avenger
• Beekeepers Naturals lollipops for the kids
• Mommy Bliss Sleep & Immunity Blend (for my baby)
• 5mg melatonin on the flights to help them sleep and adjust to the new timezone faster

One underrated addition: 𝗮 𝗳𝗶𝗯𝗲𝗿 𝘀𝘂𝗽𝗽𝗹𝗲𝗺𝗲𝗻𝘁. Every meal is eaten out, which means way less fiber than usual. Travel quietly wrecks digestion for most people, and this is the easiest fix.

My soul has been inspired and my body is running on fumes. Watching my kids light up in a country so different from home makes it hard to say it wasn't worth it, even when every data point says otherwise. That tension is the whole thing about being a parent.

Traveling with or without kids -- what do you lean on to stay healthy? Supplements, routines, sleep hacks, real strategies. Drop it below. 👇
