Seres Therapeutics vs Microbiotica
Side-by-side comparison of AI visibility scores, market position, and capabilities
Seres Therapeutics develops microbiome therapeutics, including Vowst, the first FDA-approved oral microbiome medicine for preventing recurrent C. difficile infection.
About
Seres Therapeutics is a publicly traded clinical-stage biopharmaceutical company founded in 2012 that pioneered the development of microbiome therapeutics, medicines derived from human gut microbiota. The company's lead product Vowst received FDA approval in 2023 as the first oral microbiome therapeutic, consisting of purified fecal microbiota spores administered as capsules to prevent recurrent Clostridioides difficile infection after antibiotic treatment. C. difficile infects hundreds of thousands of Americans annually and has high recurrence rates that existing antibiotics cannot fully prevent. Vowst works by restoring a diverse, healthy gut microbiome that can resist C. difficile colonization. Seres has partnered with Nestlé Health Science for US commercialization and is developing pipeline programs for inflammatory bowel disease, oncology supportive care, and other conditions where the gut microbiome plays a pathological role. The company's success with Vowst validated the regulatory pathway for microbiome therapeutics and established Seres as the pioneer of an emerging therapeutic class with broad potential across gastrointestinal and systemic diseases.
Microbiotica raised $105M Series C in 2025 for its gut microbiome platform linking bacterial strains to disease, enabling live biotherapeutic products for cancer immunotherapy and IBD.
About
Microbiotica applies genomics and machine learning to map the gut microbiome's causal role in disease, then develops live biotherapeutic products (LBPs) targeting the specific bacterial strains responsible. The company's Reference Microbiome database — built from thousands of patient samples — is the world's most comprehensive catalog of gut bacteria linked to disease outcomes, providing a systematic foundation for microbiome drug discovery.
