Overview

Yseop’s platform supports pharmaceutical companies in producing complex regulatory documentation such as clinical study reports (CSRs), patient narratives, protocols, and submission dossiers. The software is designed to integrate directly into existing regulatory workflows, enabling teams to generate and maintain documents as underlying data evolves.
The company’s technology is used by pharmaceutical organizations to reduce manual effort, improve consistency across documents, and support regulatory timelines while maintaining compliance with applicable standards.
Yseop operates internationally, with offices in Paris, Lyon, and New York.

History

Yseop was founded by Alain Kaeser, based on research conducted at École normale supérieure Paris-Saclay. In its early years, the company focused on applying symbolic AI and rule-based natural language generation to automate structured scientific and business content.
As AI technologies evolved, Yseop expanded its platform to incorporate large language models, retrieval-augmented generation (RAG), and agent-based automation, while retaining deterministic controls required for regulated use cases. This hybrid architecture was developed to address limitations of standalone generative AI systems in regulatory contexts, such as reproducibility, explainability, and auditability.
The company is led by CEO Emmanuel Walckenaer. Founder Alain Kaeser remains involved in strategic and technological direction.

Products

Yseop Copilot is the company’s primary platform for regulatory and medical writing automation. It is designed for use in GxP-regulated environments and supports both data-driven and narrative content generation.
Key characteristics of the platform include:Composite AI architecture combining LLMs with symbolic AI, structured templates, and knowledge graphs.Human-in-the-loop workflows that allow subject matter experts to review, validate, and control generated content.Traceability and audit readiness, with clear links between source data and generated text.Enterprise deployment, including private cloud hosting and integration with tools such as Microsoft Word and Veeva Vault.
The platform is used across clinical development, regulatory affairs, pharmacovigilance, and chemistry, manufacturing, and controls documentation.

Industry Impact

Yseop operates within the broader adoption of generative AI in the pharmaceutical industry, where automation is increasingly applied to research, clinical development, and regulatory operations. Industry analyses estimate that generative AI could deliver tens of billions of dollars in annual productivity gains across the pharmaceutical sector.
Yseop’s approach focuses on applying generative AI within structured, governed workflows to meet regulatory expectations for accuracy, consistency, and compliance.
