#12 ▶️ Head of Growth (Anthropic): “Claude is growing itself at this point” Lennys Podcast Anthropic’s growth team launches CASH (Claude Accelerates Sustainable Hypergrowth) using Claude with Opus 4.6 to fully automate growth experimentation—from opportunity identification to post-launch analysis—achieving junior PM-level win rates on copy and UI tweaks. Anthropic’s ARR jumped from $1 billion at the start of 2025 to $19 billion by February 2026 (10× YoY growth), hitting $4 billion mid-2025 and $9 billion end-2025—a $18 billion increase in 14 months. CASH was initiated a few months ago but only began delivering reliable results after upgrading from Opus 4.5 to Opus 4.6, automating four stages of growth work (opportunity ID, build, QA/brand compliance, and analysis). Co-work’s desktop app runs a scheduled task each morning on ~20–25 Hex chart links and Slack MCP transcripts, then uses Claude to summarize top concerns and insights in Slack.

“Claire Vo installed OpenClaw via a one-line Homebrew script on separate macOS machines (three Mac minis and one MacBook Air), configured nine role-based agents (Polly, Finn, Sam, etc.) using Opus-4.6, Sonnet-4.6 and GPT-5.4 models, and linked them to Telegram bots for automating her business outreach and family scheduling.”

#1 ▶️ How OpenClaw’s AI agents run this founder’s business, family and life | Claire Vo Lennys Podcast Claire Vo installed OpenClaw via a one-line Homebrew script on separate macOS machines (three Mac minis and one MacBook Air), configured nine role-based agents (Polly, Finn, Sam, etc.) using Opus-4.6, Sonnet-4.6 and GPT-5.4 models, and linked them to Telegram bots for automating her business outreach and family scheduling. She ran “brew install openclaw” in iTerm, chose personal use, selected Opus-4.6, Sonnet-4.6 and GPT-5.4, then registered each agent as a Telegram bot via BotFather. Agent “Sam” performs a daily sweep of her CRM for product-led growth signups, enriches leads with Exa People Search, drafts and sends outreach emails via Telegram, replacing a human assistant who worked 10 hours/week. She enabled macOS Screen Sharing and Remote Login on her Mac minis to SSH into and view the agent GUIs from her laptop over Wi-Fi, removing the need for dedicated monitors, keyboards or mice.

“All About AI Uses an autonomous Claude Code agent on a Mac Mini to invoke the OpenCode CLI via OpenRouter on four models (GLM5, Minimax 2.5, Gemini 3 Pro, Opus 4.6) in parallel to generate HTML demos of a retro space game, convert them with Remotion into a grid-style MP4 video, and draft a post on X.”

#2 ▶️ How to Run OpenCode Inside an Autonomous Claude Code AI Agent All About AI Uses an autonomous Claude Code agent on a Mac Mini to invoke the OpenCode CLI via OpenRouter on four models (GLM5, Minimax 2.5, Gemini 3 Pro, Opus 4.6) in parallel to generate HTML demos of a retro space game, convert them with Remotion into a grid-style MP4 video, and draft a post on X. Executed “open code run --model openrouter GLM5 'Should I walk or drive to the car wash? It’s 50 m away'” via Cloud Code CLI, receiving “you should walk to the car wash,” and then ran “open code run --model openrouter Gemini-3-Pro …” obtaining “drive. You can’t wash the car if you leave it behind.” Created a Cloud Code skill file open code test skill.md to launch four OpenRouter models (GLM5, Minimax-2.5, Gemini-3-Pro, Opus-4.6) in parallel on the prompt “create a full screen animated retro arcade space battle scene,” saving outputs as llm-test/game- .html.
