At HAYA Therapeutics, we are pioneering a new class of programmable RNA-guided therapeutics that target the regulatory genome to reprogram disease-driving cell states. By decoding the causal biology of pathological cell states and the long-noncoding RNAs (lncRNAs) that regulate them, HAYA translates these insights into tractable therapeutic candidates designed to address disease at its source and restore cellular health. HAYA is advancing a broad pipeline of RNA-guided medicines for chronic, age-related diseases.

Recognized globally for our scientific innovation, HAYA has been named a 2025 Technology Pioneer by the World Economic Forum (WEF), selected for BioSpace's NextGen Bio Class of 2026, recognized as a 2026 Disruptive Pioneer by IDEA Pharma, and celebrated as one of the Top Innovative Companies in Switzerland for 2025. As a fast-growing biotech, we offer an entrepreneurial, science-driven environment where you’ll have a direct impact on shaping our pipeline and advancing RNA medicine
