can persist for years without obvious symptoms and is linked to obesity and other chronic diseases. The is being studied for its role in inflammatory and metabolic signalling, including how engineered probiotics could influence these pathways.

1stBiome engineers beneficial gut microbes to reduce low-grade inflammation in the colon. It is developing oral nutritional products for metabolic health, weight management and healthy ageing, with a partner-led route to market through established consumer health and nutrition brands.

Key Investor Signals

Repeat-founder exit and scale-up experience

Co-founder Morten Sommer previously co-founded Microlytic, acquired by Anatrace in 2015. CEO Ejner Bech Jensen previously co-founded Agrobiomics and led it through a EUR 4M seed round.

Secured EUR 500,000 in BII Venture Lab financing

1stBiome joined ’s 12-month Venture Lab in March 2026, receiving EUR 500,000 in financing to advance the company.

Preclinical evidence supports metabolic effects

A 2026 reports that the lead reduced food intake, limited weight gain, increased energy expenditure and lowered inflammatory signalling in a mouse obesity model.

Product

1stBiome is developing engineered probiotic microbes for oral nutritional products aimed at metabolic health, weight management and healthy ageing. Its lead work uses Saccharomyces boulardii and is designed for commercialisation through established consumer-health and nutrition brands.

Engineered probiotic platform

Uses Saccharomyces boulardii, a probiotic yeast with established gastrointestinal use, as an engineering base for adding new functions in the gut. This gives 1stBiome a familiar biological starting point for developing differentiated products.

Targets multiple gut metabolic pathways

The platform is designed to reduce inflammation-related compounds in the colon while influencing microbial activity, appetite control and metabolic signalling, giving the company several biological routes through which to address metabolic health.

Partner-led commercial model

1stBiome plans to commercialise oral nutritional products through consumer-health and nutrition partners, using established brands, distribution and customer reach rather than building a standalone consumer channel.

Market Overview

Low-grade inflammation is associated with obesity and other chronic diseases, making metabolic health a major target area. estimates that 890 million adults lived with obesity in 2022, while a global modelling study estimated 1.54 billion adults with in 2023.

The commercial category is already substantial, with dietary supplements among the fastest-growing probiotic product segments and yeast among the fastest-growing ingredients. The market includes large potential partners such as Novonesis, IFF, Kerry, ADM, Danone, Nestle, Yakult and BioGaia, which fits 1stBiome's stated partner-led route to market.
