1,178 AI Workers Sign a Letter Urging the US to Deliberately Pace Frontier AI

1,178 current employees of leading AI companies — including OpenAI, Anthropic, Google DeepMind, Meta and Thinking Machines — signed a joint statement, “Pacing the Frontier,” calling on the US government to help build the technical and policy tools needed to “deliberately pace” cutting-edge automated AI development in coordination with other companies and countries. Signatories include Anthropic chief scientist Jared Kaplan, OpenAI chief scientist Jakub Pachocki and Meta chief scientist Shengjia Zhao. The demand — that governments help create the means to control the speed of autonomous AI — is a notable internal call for a slowdown, arriving after a string of autonomous-agent containment failures.

Meta and BlackRock Unveil a $14 Billion El Paso AI Data Center Venture

Meta announced a strategic joint venture with asset manager BlackRock to build a large AI data-center campus in El Paso, Texas, at a total development cost of about $14 billion. The striking detail is that Meta holds only a 20% stake, illustrating the spread of off-balance-sheet structures that share the heavy capital burden of AI infrastructure with outside investors. The deal lands as financing costs for the AI data-center boom rise alongside record bond issuance, and as credit-rating agencies warn that “AI exuberance” is becoming a meaningful global credit risk.

Venture Money Rushes Into the AI “Control Layer” — Security and Governance Startups Raise in a Single Day

On July 28, venture capital concentrated not on foundation models but on the control layer that makes AI usable safely in production. Cloud access-control startup Act Security emerged from stealth disclosing $60 million across seed and Series A (with Team8, Bessemer and Notable Capital; its founders previously built Medigate, acquired by Claroty for $400 million). Hush Security, which governs non-human identities and AI agents, closed a $30 million Series A (total $41 million) with Akamai joining. Hush cites Gartner’s projection that the average Fortune 500 firm could run more than 150,000 AI agents by 2028, and pitches a central registry, no standing credentials, just-in-time permissions, continuous logging and an emergency kill switch. Per Crunchbase, startups at the intersection of AI and security have already raised $855 million across more than 150 seed rounds this year — a record pace.

Voice AI Startup Fish Audio Raises a $52M Seed on $21M First-Year ARR

Fish Audio, which targets expressive voice generation, raised a $52 million seed that looks more like a Series A. In its first year it surpassed $21 million in ARR and 8 million users, spanning real-time text-to-speech, voice cloning and voice agents. It built early traction through an open-source repo and counts HeyGen and Sanas among its customers. Led by Coreline Ventures and Capital Today, investors are betting the voice market will not be winner-take-all around a single platform but open to specialists combining open-source adoption, developer controls and enterprise APIs. The caveats: competition from ElevenLabs and others, and consent questions around uploaded voices that make trust and rights management part of the product.

Money Also Flows to the Enterprise-AI “Reliability Layer” — Semantics and Vertical AI

The same roundup showed capital moving into the meaning-and-reliability layer of enterprise AI. Credible Data raised a $10 million seed (Gradient, SignalFire, K5 Global) for a “trusted business context engine” built on the open-source semantic modeling language Malloy, letting agents interpret a warehouse’s governed metrics, rules and relationships correctly at runtime. In vertical AI, Procode raised a $10 million Series A (Health Velocity Capital) to apply a fine-tuned model to surgical billing codes, expanding across 350-plus plastic-surgery and dermatology providers. The shared message is clear: investors are buying trustworthy outputs and measurable ROI in high-stakes settings, not AI that merely “sounds smart.”

Today’s Takeaways

An unusual internal call to “deliberately pace” frontier AI drew 1,178 signatures, including top research leaders.
Capital moved simultaneously into mega-infrastructure (Meta–BlackRock’s $14B data center) and the AI control, governance and reliability layers (security, semantics, voice, vertical AI).
In short, the day’s theme was not “bigger models” but “how to run autonomous AI safely and reliably.”
