When you're betting on strangers, rehearse first: shared segments, persona interviews, one Ship / Fix / Pivot read, and outreach drafts your team can actually post.
"Before we rebuild onboarding, who would actually object to the current version?"
Interview the personas you'd be rebuilding for. See the objections and switching costs before you commit a sprint to the rewrite.
"Should we lead with Product Hunt, Xiaohongshu, or cold outbound for this segment?"
Get segment-tailored promo drafts (X thread, Xiaohongshu post, cold email) for each core audience — and see which persona each one speaks to.
"We're entering a new vertical. Is this worth a quarter of build time?"
Run the audience + projection loop before the kickoff meeting. Walk in with real analogue companies and a ship / fix / pivot projection — not a hunch.
"We go live in two weeks. Is our page speaking to the personas who will actually show up?"
Stress-test the story with the segments that matter, tighten objections, regenerate copy — walk in with a rehearsed narrative.
Generate segments + named personas from a URL or one sentence. Core / adjacent / edge / non-target labels included.

SaaS tool, consumer app, open-source project, e-commerce brand, agency offer — if you can describe it in a sentence or link to a page, the personas, interviews, and projection adapt to it.
