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).
An n8n template combines an Ollama agent, three Supabase vector knowledge bases, Postgres memory, request validation, deduplication, and confidence-based escalation across Slack, Gmail, and callbacks.
Jax describes a personal CRM built from Supabase, four MCP operations, and Markdown workflows. Claude enriches a supplied profile with Harmonic, attaches Granola notes, and supports contextual searches across contacts.
This workflow OCRs uploaded receipts, stages parsed blocks in Supabase, and uses a travel-expense agent with a calculator to return a structured reimbursement breakdown.
