Sherpa.ai

Bilbao-based Sherpa.ai builds privacy-preserving AI infrastructure, including federated learning that lets organizations train and deploy models without pooling sensitive data in one place.

For sectors like healthcare and finance, where data can't easily be centralized, this approach unlocks AI that would otherwise be off-limits. The company has worked with large enterprises on privacy-first machine learning.

It addresses one of AI's central tensions: the need for data versus the duty to protect it.
