- Raised $20M Seed round led by TLV Partners, Sep 2025
About
Attestable is a Tel Aviv-based startup focused on developing an 'AI trust-layer' to ensure system integrity by verifying AI models, prompts, and outputs. The company aims to secure AI usage and prevent malicious tampering in response to growing concerns over the reliability of generative AI systems. They are addressing the brittleness and manipulation risks of current AI technologies. Attestable is taking a markedly different angle, focusing on a security layer that will help companies and organizations ensure that digital agents do not misuse incorrect data produced by one of them or by another malicious agent. The company is interested in bringing to the AI stage a technology from the world of blockchain known as "Zero Knowledge Proof", which allows digital financial networks to verify the identity of the account holder or the authenticity of the financial data transmitted by ensuring its correctness, while providing minimal data to the other party.
