Runlayer wants to secure the rise of agentic AI

As AI agents gain autonomy, Runlayer is building the security layer that validates and governs agent behavior across enterprise workflows.

What Runlayer provides

  • A Model Context Protocol (MCP) security wrapper.
  • Tools to validate agent requests and outputs.
  • Policy enforcement engines for sensitive tasks.

Why this matters


  • As agents gain planning and execution powers, security risks multiply.

  • Enterprises need auditability and trust boundaries for agent actions.

  • Runlayer targets the emerging market of agent-security infrastructure.

Why it matters


  • Helps prevent unintended or unsafe agent behaviors.

  • Could become foundational as agent workloads proliferate.

  • Highlights a new category: “agent security platforms.”

Google's chief scientist walks: Jeff Dean leaves after 27 years, taking three legends with him

Jeff Dean, Google's chief scientist and 30th employee, is leaving after 27 years to found Discovery Loop, a public benefit corporation using AI to automate scientific research - taking co-founders Sanjay Ghemawat, Quoc Le (Google Brain), and Oriol Vinyals (DeepMind) with him. Google is a founding investor and cloud partner, supplying compute for at least the first year, with Radical Ventures and Khosla Ventures co-leading the seed. In the same announcement, Demis Hassabis steps down as DeepMind CEO to become chairman and Alphabet chief scientist, with Koray Kavukcuoglu taking over Gemini model development. Alphabet stock fell about 4%.

Anthropic signs a $10B, six-year compute deal with a startup that didn't exist last year

Anthropic has reportedly signed a $10 billion, six-year compute deal with Volta, an AI cloud startup founded only earlier this year, per Bloomberg. Volta is partnering with crypto-mining firm Bitdeer to develop the data centre - located in Norway, delivering 133 megawatts, and running Nvidia's Vera Rubin architecture - and is a member of Nvidia's Cloud Partner programme. It caps an aggressive capacity spree that also includes recent compute deals with SpaceX and Amazon, as Anthropic races rivals for the scarcest input in the industry.

Airtable sells for $1.28B after an $11B peak - the first big AI-era valuation reset in SaaS

Bending Spoons agreed to buy Airtable for $1.28 billion in cash (about $2.25B equity value including net cash) - its first acquisition since a July Nasdaq IPO at an $18 billion valuation. The reset is stark: Airtable raised over $1.4 billion and peaked above $11 billion in 2021, with secondaries reportedly at $4 billion earlier this year, even though ARR grew 20%+ year-over-year to roughly $480 million and it serves 500,000+ organisations including 80% of the Fortune 100. Bending Spoons - owner of Evernote, WeTransfer, Eventbrite, and Vimeo - typically buys at a discount, trims staff, and optimises for profit.
