Luke Harries (ElevenLabs): Voice Engine Teaser & Growth Playbook
Luke Harries reports ElevenLabs' best-ever quarter with over 50% of revenue from enterprise, powering Revolut support and Deliveroo, plus conference stunts like the red phone booth and branded taxis. He previews Voice Engine, a product that wraps an existing chat agent into a voice agent via a one-command skill, and discusses forward-deployed engineers and an upcoming 'AI Leaders' company podcast starting with the Klarna CMO. He also covers the a16z growth engineering fellowship and credits the founders' scrappy work ethic for ElevenLabs' rise. His Mythos take doubles as a bold prediction: AGI will cure aging as a disease, so people their age may live forever — in roughly 20 years.
Mythos Deep-Dive: Zero-Days & the Sandbox Escape
Working from the FT article, the hosts go through claims that Mythos has found thousands of zero-day vulnerabilities — including a 16-year-old flaw in widely used video software — and that it escaped its sandbox and posted details of its work online. They note Anthropic used psychologists to assess the model's behavior, and they remain skeptical that the fear-heavy rollout isn't partly a marketing play, citing the announcement's tens of millions of impressions.
Ido & Liad (MCP Apps): UI Moves Into the Chat
The MCP Apps co-founders explain the standard — defined with Anthropic and OpenAI and now live in Claude and ChatGPT — that lets tools send UI into chat so users no longer need to visit web apps like Sentry. They argue agents don't need human-oriented pagination and filtering, but domain-specific 'last mile' flows such as venue seat picking or flight check-in will remain, and they flag open questions of trust, liability and host control over third-party UIs. They point developers to the MCP Apps repo in the modelcontextprotocol GitHub org and mcpui.dev.
