Demo Builder
Build personalized demo assets for prospects using the founder's product API/MCP/SDK. Send a working prototype that solves the prospect's actual problem — with a comparison report and live demo link.
When to Use
User provides a prospect company name or URL and wants a demo built for them
User asks to "build a demo", "create an asset", or "personalize outreach" for a specific company
User has a product with API access, SDK, MCP server, or CLI and wants to demonstrate it to a prospect
User has completed a lead generation run and wants to act on the results
User asks "what do I do with these leads", "how do I reach out", or "help me with outreach"
Prerequisites
API access, MCP access, SDK, or CLI for the user's product — the agent needs to be able to actually build something
Access to the product's documentation (API docs URL, SDK readme, or MCP tool list)
Phase 1: Identify the Prospect
This skill supports two input paths:
Path A: User provides a prospect directly (primary path)
If the user provides a company name, website URL, or prospect details:
Accept the prospect as-is — no lead data required
Proceed directly to Phase 2 (Research the Prospect)
Ask the user:
"I'll build a working demo for [Company]. Before I start, I need to know:
What does your product do? (one-liner)
What problem does it solve for companies like [Company]?
Where are your API docs / SDK / MCP tools?"
If the user has already provided product context (from lead-discovery or prior conversation), skip questions they've already answered.
Path B: User has signal data from prior lead generation runs
If the user has csv outputs from signal skills, help them pick the best prospect:
Read the csv outputs and identify top candidates by looking for multi-signal leads, switching signals, build-vs-buy signals, high interaction scores, community pain signals, or company clusters
Write high-converting cold emails using structured frameworks, personalization tiers, and patterns from real campaigns. Pure reasoning skill — no scripts. Auto-loads when any task requires outreach copy.
