TL;DR — THE STACK IN 60 SECONDS Don't collect tools. Assign them jobs. Seven jobs cover a growth team: thinking, research, writing, visuals, video, automation, and data. Pick ONE primary LLM (ChatGPT, Claude, or Gemini) and learn it deeply. Depth beats variety. The starter stack: one LLM + Perplexity + Zapier or Make + Canva + one specialist for your biggest bottleneck. Roughly $150–200/month. AI compresses execution, not judgment. It makes a good growth process faster. It cannot replace one.
