About Yseop

Yseop is a health AI company specializing in regulatory-grade artificial intelligence for the life sciences industry. The company's flagship product, Yseop Copilot, automates the creation of regulatory documents and medical writing content with a focus on accuracy, traceability, and compliance required for pharmaceutical submissions. Unlike general-purpose AI tools, Yseop's platform is purpose-built to pass strict regulatory review and audit requirements. The company employs a composite AI strategy that combines symbolic AI with large language models (LLMs) to deliver deterministic, traceable outputs. This neuro-symbolic approach ensures every sentence is linked to its source data with a full audit trail, addressing the critical need for accountability in regulated content generation. Yseop's technology automates core regulatory documents across the CTD pyramid, including clinical study reports (CSRs), patient narratives, and other submission materials. Yseop serves major pharmaceutical companies including Eli Lilly, GSK, and Sanofi, helping them accelerate drug submission timelines while maintaining regulatory compliance. The platform integrates directly with Microsoft Word and Veeva Vault, fitting seamlessly into existing document workflows. With validated outputs requiring less than 7% re-authoring in production use, Yseop has demonstrated significant time and cost savings—reducing patient narrative generation from 4 hours to 4 seconds per document. The company was recognized as one of TIME's Best Inventions of 2025 in the Medical & Healthcare category, acknowledging its impact on transforming regulatory workflows in the pharmaceutical industry.
