Tiny Health at a glance

Tiny Health was founded in 2020 by Cheryl Sew Hoy in Austin, Texas, after her own child developed eczema and food intolerances. Unable to find an infant gut test capable of identifying the root cause, she built one. Today, Tiny Health is the first precision microbiome wellness platform designed to track health across the full family lifespan — from pregnancy and the first 1,000 days of life through adulthood.

Each possible association is then checked against the company's large internal dataset of metagenomic samples. This step confirms it actually holds up before it ever appears in your report. The platform identifies microbes at the species level, and sometimes even at the strain level, using its own bioinformatics pipeline. It doesn't stop at listing which microbes are present — it also looks at what those microbes are capable of doing, like producing short-chain fatty acids (SCFAs), breaking down fiber, and keeping the gut barrier strong. Reference ranges for each metric in the test are calculated individually, so results are benchmarked for where you actually are.

Tiny Health has served more than 150,000 people and works with over 5,000 health practitioners. A published, peer-reviewed randomized controlled trial found that babies who got personalized microbiome support through the Tiny Health program had 83% lower odds of developing eczema [2].

Jona at a glance

Jona is a New York-based health tech company that applies artificial intelligence to gut microbiome sequencing. Founded in 2022 by Leo Grady, PhD, an AI researcher, Jona's core premise is that the hard part of microbiome testing isn't the sequencing. It's the interpretation. Their AI system indexes peer-reviewed papers and maps your microbial results against what the current literature says about conditions, symptoms, and interventions. The result is a personalized report that compares your microbiome's association to dozens of health conditions, along with food, supplement, and lifestyle recommendations pulled directly from the science.

Jona's primary audience is adults who are dealing with undiagnosed or ongoing symptoms and want a research-grounded starting point. The company has also built a version for clinicians who want to use microbiome insights in patient care.

Detailed comparison: Tiny Health vs Jona 

The sections below break down each major decision point in more depth, from what's actually happening in the lab to what you get when your results land in your inbox.

Technology & testing methodology

The sequencing method a company uses shapes everything: what organisms it can detect, the depth of insight it can offer, and whether results might change as science advances. As our guide to shotgun metagenomics vs. PCR, 16S, and RNA-Seq explains, not all microbiome tests look at the same picture.

Both Tiny Health and Jona use shotgun metagenomic sequencing — the gold standard in the field. This approach sequences all the microbial DNA in your stool sample, including from bacteria, fungi, viruses, and parasites. At the level of raw sequencing, the technology both companies use is excellent.

The two companies diverge in how they build on that sequencing data.

At Tiny Health, once your sample is sequenced, the raw sequencing data goes through a custom bioinformatics pipeline that Tiny Health built in-house. This pipeline figures out which microbes and genes are present. Because Tiny Health controls every step of this process, instead of relying on an outside tool, the system is fine-tuned to catch the microbes that matter, without falsely flagging ones that aren't really there.

Beyond just identifying microbes, Tiny Health also looks at what those microbes can do. Knowing a certain microbe is present tells you one thing. Knowing whether it can make butyrate (an SCFA that fuels your gut lining) or break down estrogen tells you something much more useful [3,4]. For a deeper look at how these approaches compare, the blog At-Home Gut Microbiome Testing: What It Measures and How It Works breaks down the science. 

Tiny Health's microbiome scientists use AI to stay current with emerging research and surface new associations.  From there, they validate all associations against an internal dataset of tens of thousands of microbiome samples. This allows Tiny Health to stay on the cutting edge of microbiome science while ensuring every insight and recommendation has been validated by scientists with deep expertise in the field. 

Jona sends sequencing data through a third-party bioinformatics platform, then uses its own AI model to interpret the results. Jona's big selling point is scale: its AI has indexed over 600,000 papers. But a bigger library doesn't always mean a more reliable result. The AI may build associations from papers that used different methods or weaker data. Reports focus on which microbes are present and how they relate to conditions, symptoms, and diet, along with personalized food, supplement, and lifestyle suggestions based on your results. The report does not include gene-level analysis — meaning it doesn't check whether the genes needed for specific jobs, like producing butyrate, are actually present in your sample. Instead, Jona reports on how much of certain microbes are present, based on what they're known to do.

One thing worth noting: Jona's AI draws from research that uses different sequencing methods, including 16S sequencing studies, which identify microbes differently than shotgun metagenomics does. Associations built from these different data types aren't always comparable to each other. And since there's no scientific team checking whether an association is actually meaningful before it reaches your report, the quality of your results depends heavily on the quality and consistency of the studies the AI was trained on. Tiny Health's process works the other way around: nothing reaches your report until it's been checked against real-world data first.

Sample collection and user experience

Getting the sample from your bathroom to the lab is when many people first hesitate about microbiome testing. Both companies try to minimize friction in this process.

Tiny Health uses a validated, dry swab collection method [5] — no liquid buffer, no spill risk. You touch the swab to used toilet paper, so no handling of stool is required. The swab uses a drying agent (called desiccant) to keep microbial material stable at room temperature. This means you can mail the sample whenever it's convenient, ideally within five days of collecting it. Helpful demonstrations are available on the Tiny Health website. Results typically arrive within 2-3 weeks.

Jona ships the next day and describes its collection process as a "mess-free stool sample collection." Based on their product page, everything needed for a clean process is included in the kit. After collection, you ship the sample to their CLIA-certified laboratory. Results arrive within 2-3 weeks.

Personalized recommendations: How actionable are the insights?

Sequencing data is only useful if it tells you what to do. How each platform turns raw results into guidance is where the two approaches diverge most clearly.

Tiny Health's recommendations are built by microbiome scientists, based on published research, and matched to your age and your own test results, not copied from a generic template. Tiny Health doesn't earn commissions from supplements or probiotics, so any product suggestion is based only on your data, not on what earns the company money. 

Every test includes a 30-minute Group Results Review, where you talk with a microbiome specialist, ask questions, and build your action plan together in real time. Tiny+ members also get ongoing one-on-one coaching, and you can bring your own doctor or practitioner into the process through PoweredbyTiny.com. Tiny Health checks its insights against its own research data, and scientists use AI to keep up-to-date with current scientific findings, updating metrics regularly as new evidence comes out. For parents, Tiny Health offers age-specific action plans made for babies, filling a gap that most adult-focused tools can't. Jona doesn't offer anything like this for interpreting a baby's microbiome results.

Jona generates an AI-driven report that maps your microbial profile against published literature to surface associations with conditions, symptoms, and potential food triggers. For each finding, the report indicates strength of evidence and suggests specific foods, probiotics, or lifestyle practices. Jona's digital twin layer simulates how dietary changes might shift your microbial balance before you commit to them. Reports also update automatically as new research is published — you might log in months later and find your associations have changed based on new science. Jona also states they have no supplement affiliate relationships.

Jona's reports don't include gene-level functional data. You'll learn which organisms are present, which functions they're known to perform, and which conditions the literature associates with your profile — but not whether the underlying genes required for those functions are actually present in your sample. The recommendations you do receive are generated entirely by AI, so their reliability is only as good as the research behind them, with no scientific team weighing in on whether a given finding is strong enough to act on.

Verified reviews: What people are saying about Jona and Tiny Health

Tiny Health testimonials

The following reviews appear on Tiny Health's official reviews page:

Brad W.: "I've been getting into gut health over the last couple years and have even taken other test kits. Tiny Health definitely is leading the space with their knowledge and reporting. I haven't even done the consult yet, which I'm looking forward to. Great work!"

Jessica M.: "Initially we were simply interested in the microbiome of our baby, and he turned out to have low levels of bifidobacteria. We found that a few days of a recommended probiotic already solved that problem! Then things got more serious. At 6 months old he was hospitalized with severe pneumonia, and needed the most extreme antibiotics to save his life. It took a while but after months of following Tiny Health's advice, no trace of potentially antibiotic-resistant bacteria are left!"

Mary: "100% Recommended. Results are easy to understand and there is a lot of useful information regarding gut health and overall health as well. Love how results are presented and how easily you can have a consultation call in case you want more information."

Rich Maurer: "My grandson and I both took the same strain of B. infantis and we were the first consumers to have this strain detected in our Tiny Health gut test. No other testing company was able to detect this beneficial strain, which completely turned around my grandson's gut from extremely inflammatory to anti-inflammatory. It also reestablished a healthy amount of bifidobacteria in my gut. Thanks, Tiny Health"

Jona testimonials

The following reviews appear on Jona's product page and Jona’s Facebook page:

Jason: "This is the second biome test I’ve done. One with Jona and one with another brand. Jona was far more expensive (almost double) and I feel like the experience was not worth it."

Michelle: "My Jona report told me that I couldn't digest gluten or lactose and that I had an association to IBS along with lots of advice to help the condition. With the help of the dietitian, I started following the report suggestions and within a few weeks everything changed, I no longer had any problems with constipation."

Jen: “I was excited to do this and I went thru the process which isn’t the most pleasant (not Jona’s issue- just not fun collecting your own sample). Anyway, once I was ready to mail in, you have to register before you do and their site doesn’t work. I tried on all my Mac devices and cleared cache and it just comes up blank. Not cheap and not a good experience.”
