Seres Therapeutics vs AbCellera
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.
Vancouver-based antibody discovery platform with 104+ partner programs; $75M FY2025 revenue. Expanding into wholly owned assets with ABCL635 in Phase 1 for vasomotor symptoms.
About
AbCellera Biologics was founded in 2012 in Vancouver, Canada by Carl Hansen, growing out of research at the University of British Columbia. The company built a high-throughput antibody discovery platform integrating microfluidics, genomics, single-cell sequencing, and AI/ML to rapidly identify therapeutic antibody candidates from natural immune responses. AbCellera played a prominent role in the COVID-19 pandemic by discovering bamlanivimab for Eli Lilly in under 90 days.\n\nAbCellera's partnership model operates on a discovery fee plus downstream milestone and royalty structure, having started over 104 partner-initiated programs with downstream participation as of December 2025. Partners include major pharmaceutical companies and biotechs; the company expanded its collaboration with AbbVie in 2025 to develop T-cell engagers for oncology. Total FY2025 revenue was $75 million ($47M from royalties/licensing, $27M from partnered program work), compared to $29 million in 2024—a dramatic increase driven by royalty flows from approved medicines.\n\nIn 2025 AbCellera began transitioning from pure partnership model toward wholly owned therapeutic assets, with ABCL635 (a GnRH receptor antibody for vasomotor symptoms) entering Phase 1. The company maintains approximately $700 million in liquidity, providing a long runway. AbCellera is considered a foundational infrastructure provider for the antibody-based drug discovery ecosystem.
