Attestable completes AI verifiable technology breakthrough, secures $20 million in seed round financing

AI security startup Attestable has officially announced its establishment and completed a $20 million seed round financing. This round of financing was led by Jamin Ball of Altimeter Capital and Yonatan Mandelbaum of TLV Partners, with participation from institutions such as Halcyon Futures, Cerca Partners, and several investors.Attestable founder Yogi stated that as AI gradually enters critical infrastructure, national security, and large enterprise systems, how to verify the credibility of AI operations has become an important issue faced globally. The company aims to build a universal verification layer for cutting-edge AI laboratories, critical infrastructure, and national-level applications.According to reports, Attestable uses Zero-Knowledge Proof technology to shift trust in AI systems from data centers to mathematical verification mechanisms. This technology can prove that a certain approved model, model weights, input data, and operational strategies indeed generated specific outputs, while not disclosing model parameters or user privacy data, and without needing to rerun the model for verification.Attestable stated that its technology has currently achieved verification inference of the Meta Muse Glimmer 30B model on a single NVIDIA H100 GPU, reaching a speed of 85 tokens per second. The generated proof documents are small and possess quantum-resistant characteristics, allowing for rapid verification.In response, Ethereum co-founder Vitalik Buterin commented, stating that this achievement means the performance loss of Zero-Knowledge Proofs for large language models is approaching single-digit levels. He noted that the next challenge is to further reduce the performance overhead of technologies such as Fully Homomorphic Encryption (FHE).

hot_img Yushu Technology starts subscription, Meituan and Sequoia may become the biggest external winners, DJI misses out on approximately 3.7 billion yuan in floating profits

Yushu Technology officially launched online and offline subscriptions on August 10, with an issue price of 150.80 yuan per share. The total market value after issuance is approximately 60.993 billion yuan, with total fundraising of nearly 6.1 billion yuan, and the issuance price-to-earnings ratio is 219.23 times, significantly higher than the industry average of 38.56 times.Meituan holds a total of 9.65% of Yushu's shares before issuance through its three subsidiaries, making it the largest external institutional shareholder; Sequoia China holds a total of 7.11%, ranking second. Based on the issue price, the two institutions will receive substantial paper returns. Sequoia first participated in the capital increase in December 2019 with 15 million yuan, at which time the post-investment valuation was only 150 million yuan.A fund under DJI planned to invest 10.1286 million yuan in 2018 for a corresponding shareholding of about 17%, and completed the business registration, but chose to withdraw its investment in 2019. If this investment had been retained until now, the corresponding market value would be approximately 3.7 billion yuan based on the issue price. DJI did not explain the reason for the withdrawal, but in 2019, the company announced an anti-corruption notice, disclosing the handling of 45 employees suspected of corruption, which led to a complete halt of the investment department's work.Among other major shareholders, Jingwei Venture Capital holds 5.45%, Shunwei Capital holds 4.42%, and CITIC Securities holds a total of 4.49%. In terms of strategic placement, DeepSeek received 933,400 shares (subscription of 141 million yuan), and Shanghai Qishan Investment, a subsidiary of Tencent, received 903,300 shares. CITIC Securities, as the sole sponsor, will receive approximately 145 million yuan in sponsorship underwriting fees and will be allocated 808,900 shares through co-investment. Yushu also reminds that the issuance price-to-earnings ratio is significantly higher than the industry average, posing a risk of stock price decline. The deadline for payment for successful applicants is August 12.
