AI Safety & Security Researcher

Giskard defends the vision of a Responsible AI that serves the economic performance of companies while respecting the rights of citizens. To embody this mission, we are building a holistic testing platform for AI professionals to evaluate the quality & security of Generative AI applications based on Large Language Models (LLMs).

Since 2021, we’ve been building based on open-source foundations (4K stars on GitHub) and pushing the frontier of applied AI Safety & Security research, to help major customers secure their GenAI applications, including BPCE, SG, AXA, Michelin, and more.

Company track record

In 2022, we raised our first round of 1.5 million euros, led by Elaia, with notable angel investors including Hugging Face’s CTO and Mistral AI’s co‑founder. To read more about this fundraising, you can read our announcement.

In 2023, we received a strategic investment from the European Commission to build a SaaS platform to automate compliance with the EU AI Act. You can read more here.

In 2024, we won a 3 M€ grant from Bpifrance to lead research in evaluation & mitigation for LLMs, in a collaborative consortium with Mistral AI, Artefact, INA and BnF. You can learn more here.
