Indie Hackers founder Sean Prentice used Claude Code to build an orchestrator + marketing director + specialist agents (content/ads/research) for his SaaS; outputs land in Slack and nothing posts or spends without his explicit say (~$10/mo self-use).
Articos lets SaaS/agency teams paste a site, generate stance-diverse synthetic personas, and get a structured research report (objections, language, recommendations) claimed at 86% fidelity vs expert studies—built for agent-era messaging tests.
