Zama

Zama is an open-source cryptography company headquartered in the center of Paris, focused on developing Fully Homomorphic Encryption (FHE) solutions for blockchain and AI. The company has raised $73 million in Series A funding and offers a suite of products including TFHE-rs, Concrete, Concrete ML, and fhEVM. Zama’s technology enables encrypted computations on data without decrypting it, providing solutions for confidential machine learning and confidential smart contracts. Concrete ML is a privacy-preserving machine learning framework built on top of Concrete, supporting various models such as linear models, tree-based models, and neural networks. fhEVM is a fully homomorphic encryption protocol designed for writing confidential smart contracts on public blockchains. Concrete is a TFHE compiler that converts Python programs into FHE equivalents, while TFHE-rs is a pure Rust implementation of the TFHE scheme for boolean and integer arithmetics over encrypted data. Zama’s solutions are modular and designed to integrate future innovations, with applications in healthcare, finance, advertising, defense, biometrics, and government. The company’s technology enables private inference, private training, and secure collaboration in machine learning, and can be used for encrypted photo filtering, sentiment analysis, health predictions, and credit card approval predictions. Zama actively participates in open-source communities, driving the future of technology and privacy, with the aim of making end-to-end encryption mainstream.
