Buttermilk

Buttermilk came with a list. Not a brief, a list. Seven distinct pain points across outbound, sales ops, client onboarding, and internal handovers. Every item had a human cost attached to it. Hours per week, errors per month, team members cc'd into threads they should never have needed to see.

The build ran in two phases. First, the lead engine. Claude and Perplexity score each prospect against the agency's ICP before a single message is sent. Clay enriches. Expandi delivers across email and LinkedIn. The pipeline runs end-to-end in n8n. No human in the loop until a reply lands. That shipped in week two. By week three, Buttermilk had stopped manually qualifying leads.

Phase two covered the internal layer. The brief generator turns intake inputs into a formatted, branded document ready for account-team review. The team handover system moves context between people without the Slack thread that usually carries it. Sales pipeline state consolidates into one dashboard rather than four tools that contradict each other. Four surfaces, one n8n backbone, handed over with source JSON and a Loom walkthrough. The "where's that doc" thread has not appeared since.
