The nuncio
playbook

Worked examples of great personalised outreach. Each one shows the recipient, the brief, the generated script, and a teardown of what made it land — and what was deliberately left out.

Composite examples for illustration. Names and details may be fictionalised.

Sender brief

I'm building nuncio, an agentic video personalization pipeline that uses HeyGen to turn public profile context into a short, tailored outreach video. I'd love feedback from a HeyGen product perspective on making developer-facing video agents feel genuinely useful and not like generic automation.

Generated script

Hey Onee — I came across your work on the HeyGen developer platform, and your recent push to make the Video Agent API more agent-friendly really resonated with me. I'm building nuncio — it's a pipeline that takes someone's public profile, researches them, writes a personalised script, and renders a video using HeyGen's Video Agent. The whole thing runs autonomously in about 90 seconds. What I'd love your perspective on is this: how do we make developer-facing video agents feel genuinely useful rather than just "AI slop with a face"? Your work on the CLI and the MCP connector suggests you've thought deeply about this. I have a few specific questions about prompt structure and scene composition that I think would take 15 minutes. Would you be open to a quick call next week?

Why this works

References his specific work (Video Agent API, CLI, MCP connector) — not just his title

Positions the ask as product feedback, not a sales pitch — flattering without being sycophantic

Shows the sender has already built something with HeyGen — credibility signal

Specific time ask (15 minutes) — low commitment, easy to say yes to

This works because it demonstrates the sender has done real work with HeyGen's tools and is asking for expertise, not attention. The recipient feels like a peer being consulted, not a target being pitched.

Deliberately skipped

His personal background/education — too generic, not relevant to the ask

HeyGen's funding/valuation — corporate context doesn't help a product conversation

Generic compliments about 'amazing product' — hollow without specifics
