The Founder’s Playable Brief: A 1‑Page Template to Turn an Idea into a Clickable Demo in 90 Minutes

A playable brief’s job is narrow: frame the problem, explain the aha hook that makes the demo feel like a product, and define the minimal microflow you must show for users to feel value. Keep it one page — constraints force clarity. Include only the elements that directly influence the clickable demo: problem, aha hook, must‑show microflow, one success metric, acceptance tests, and a short privacy checklist.

The brief is not a PRD. Skip long UX stories, backlog lists, and technical implementation notes. The goal is to align you and any designer on what to build and how you’ll know if it worked after a short experiment. Use plain language and a single number for success (e.g., “5% of visitors complete booking flow”).

Use this exact structure to keep the brief compact and action‑oriented. Fill each field with a single line or bullet. If you can’t articulate a clear success metric or a must‑show microflow, don’t build the demo — talk to users instead.

Template (one line per field): Title | Problem (who, what, context) | Aha hook (one sentence) | Must‑show microflow (screen 1 → screen 2 → finish) | Success metric (single number) | Acceptance tests (3 pass/fail items) | Privacy (data collected & purpose).

A playable demo should look and feel real enough for users to behave naturally. Modern flows let you use Figma’s prototype features, embed prototypes, or export static clickable HTML using plugins and Figma’s Sites/code features. Start by building the microflow in Figma with clear hotspots, then choose one of three export paths: (1) share the Figma prototype link, (2) embed the prototype in a simple HTML page via Figma embeds, or (3) export HTML with a plugin (e.g., prototype exporters) and host it.

Practical steps: design only the screens in your must‑show microflow; set prototype connections for every interactive element; preview and run the flow to confirm acceptance tests; then export or embed using Figma’s embed URL or an export plugin. If you export HTML, test the exported interactions and update hotspots in Figma when they differ after export.

Timebox everything. Example sprint: 0–10 minutes fill the one‑page brief; 10–60 minutes build the prototype (or update an existing Figma file); 60–80 minutes export/embed and assemble a single landing page that frames the demo and a clear CTA; 80–90 minutes launch to a small cohort (friends, early users, or paid traffic) and collect results. The objective is behavioral evidence — did users take the action the success metric defines?

Capture and interpret the outcome. If the metric exceeds your threshold, you’ve earned a follow‑up (more tests or an engineer). If not, use the brief’s acceptance tests and user notes to iterate: tweak the aha hook, simplify the microflow, or validate the problem with interviews. The brief keeps every iteration focused and fast.
