Most skincare gets tested on skin. Very little gets tested on what lives on it.
Elsa Jungman built HelloBiome to change that, and some of the biggest names in beauty and wellness now design products around her data.
Elsa is the founder and CEO of HelloBiome, a San Francisco microbiome intelligence company. It combines sequencing, its own clinical studies, and machine learning to find the biological patterns behind skin, scalp, and hair, then predicts how people will respond to an ingredient or formula before it ships.
Her argument is that microbiome science shouldn't be a box you check on a finished product. It should be where formulation starts.
In 2027 she joins us on the SynBioBeta stage.
What HelloBiome has built:
- A partnership with Cosmax, one of the world's largest cosmetics manufacturers, built on microbiome data from 900 consumers. The work identified microbial markers tied to sensitivity and barrier disruption, then guided which postbiotic actives went into the formula
- A scalp microbiome research program with K18, studying how hair treatments interact with the bacteria on the scalp
- Work with more than 30 clients internationally, including Nutrafol, True Botanicals, OneSkin, and ingredient makers like Takasago
- Research studies, claim studies, formulation development, and white-label microbiome testing kits for skin, scalp, and v***a
- PredictaBiome, its next step from measuring the microbiome to predicting outcomes
- Revenue that nearly tripled in 2024, with the company profitable
"We rely on clinical data that we have collected ourselves," she says. That dataset is the asset.
Her path to HelloBiome:
- PhD in skin barrier science
- L'Oréal, in product development
- AOBiome, early in the live-bacteria skincare field
- Founder of Dr. Elsa Jungman, a skincare line built for sensitive skin
- HelloBiome, Founder and CEO
She's been named to Inc.'s Female Founders 500 and the Longevity 100 in Beauty & Wellness.
Her focus now sits where microbiome science, AI, personalized health, and longevity meet, moving biological data past measurement and into prediction and precision interventions.
If you're building in beauty, personal care, microbiome diagnostics, or anywhere biological data should shape a product before it launches, Elsa is the person to find.
Come find her in San Jose, May 3-6th.
