Claude Code built the entire ICP for our next campaign while I slept yesterday.

Multiple MCPs. Multiple sub-agents. One terminal. I described what I wanted and went to sleep.

Claude Code orchestrated every step. Identified and qualified 8,378 companies. BlitzAPI mapped LinkedIn profiles from domains. Sub-agents ran waterfall ICP searches across three title tiers. Unipile and Exa filled the gaps.

A separate agent enriched every decision-maker with work emails. And then we pushed everything back to Supabase.

Opened my laptop to a clean, qualified list ready to launch campaigns from.

That's Claude Code with MCPs in production.
