Attestable Secures $20M Seed Round, Vitalik Praises ZK AI Verification Tech

Attestable closes $20M seed led by Altimeter and TLV. Vitalik commends the project's practical zero-knowledge proof tech for verifying AI outputs without exposing weights.

Woofun AI reports that AI integrity firm Attestable has finalized a $20 million seed funding round alongside its official launch. The round was led by Jamin Ball of Altimeter Capital and Yonatan Mandelbaum of TLV Partners, with participation from Halcyon Futures, Cerca Partners, Zero Knowledge Ventures, and various individual investors.

Vitalik Buterin endorsed the initiative by sharing a post from CEO Yogi, describing the work as "an impressive piece of work." Attestable states it has resolved the challenge of "practical zero-knowledge proof," enabling data centers to verify that approved models, weights, inputs, and strategies generate correct outputs without revealing private data or model weights. This process requires no private keys or model reruns. On a single NVIDIA H100, the alpha version verifies the Meta Muse Glimmer 30B model at 85 tokens per second, providing post-quantum security.
