Founded in 2023 by Marie Paindavoine, winner of the European Cyber Woman Award, Skyld has developed a hardware-agnostic software that safeguards machine learning models against reverse engineering and misuse - without slowing performance or disrupting existing AI workflows.
The global AI Trust, Risk, and Security Management market is projected to triple to $7.44 billion by 2030. Yet more than 70% of companies suffered AI breaches in the last two years, highlighting urgent demand for Skyld’s protection technology, esp. on AI powered edge devices.
“Skyld has the potential to become a category-defining leader in AI model cybersecurity,” said Tim Schwichtenberg, Senior Investment Manager of Bloomhaus Ventures. “Its first-mover advantage, world-class team, and scalable technology make it a standout in a rapidly growing market as the need for on-device AI model protection increases sharply.”
Skyld has been selected as one of the 12 best European startups in security in 2024 by the ECSO (European Cybersecurity Organization) and named among the 100 most promising AI startups at RAISE Summit 2025. The company was supported by Inria Startup Studio, accelerated by Berkeley SkyDeck and is present at Station F (Cyber@Station F and Female Founder Fellowship). CEO Marie Paindavoine was listed by Le Point as one of the 100 innovators of 2025.
