How it works

1. Research the prospect

Agent #1 scrapes their website, LinkedIn, and recent news — returning a structured dossier with pain signals and ICP fit.

2. Pick the angle

Agent #2 chooses three positioning angles and a hook variant matched to past winning proposals retrieved from pgvector.

3. Draft and package

Agent #3 writes the cover letter; Agent #4 generates a PDF landing page and 60-second video script. All queued for human review.

60-second Loom

90-second flow: paste a URL → watch four agents stream live updates → open the final proposal draft plus PDF and video script attachments.

Frequently asked questions

Is this just a prompt chain or real multi-agent?

Four specialized Claude agents (Research, Positioning, Copy, Attachments) run in parallel where possible and hand off structured JSON. An orchestrator evaluates each agent’s output before proceeding.

Where does the past-proposal retrieval come from?

A pgvector index of your best-performing proposals. When the Copy Agent drafts, it retrieves the 3 most semantically similar past wins to match voice, structure, and hook pattern.

Does it autopilot into Upwork / email / CRM?

No — drafts land in a human review inbox. One click approves and sends. Supervised-agent pattern: the human is the last mile, not removed from the loop.

What proposal hit rates do clients see?

Clients report 30–70% lift in interview conversion vs. hand-written templates, mostly driven by deeper prospect-specific research and stronger hooks.

Want one of these in your business?

We’ll scope, build, and hand off a production-ready system in 3–4 weeks.
