Attestable achieves breakthrough in AI verifiable technology, secures $20 million in seed round funding.

AI security startup Attestable announced its official launch and a $20 million seed round funding. The round was led by Jamin Ball of Altimeter Capital and Yonatan Mandelbaum of TLV Partners, with participation from firms including Halcyon Futures, Cerca Partners, and several individual investors. Attestable founder Yogi stated that as AI increasingly integrates into critical infrastructure, national security, and large enterprise systems, verifying the trustworthiness of AI operations has become a key global issue. The company aims to build a universal verification layer for cutting-edge AI labs, critical infrastructure, and national-level applications. According to the introduction, Attestable uses Zero-Knowledge Proof (ZKP) technology to shift trust in AI systems from data centers to mathematical verification mechanisms. This technology can confirm that an approved model, its weights, input data, and operational policies indeed generate specific outputs, without disclosing model parameters or user privacy data, and verification can be completed without re-running the model. Attestable noted that its technology has now achieved verification inference of Meta’s Muse Glimmer 30B model on a single NVIDIA H100 GPU, reaching a speed of 85 tokens per second. The generated proof is small in size, features quantum-resistant security, and enables fast verification. In response, Ethereum co-founder Vitalik Buterin published a post stating that this achievement brings the performance overhead of zero-knowledge proofs for large language models (LLMs) close to single-digit levels. He added that the next challenge is to further reduce the performance costs of technologies such as Fully Homomorphic Encryption (FHE).
