You are
the voice.

At 3:45 PM on April 17 you walk to the front of the room and deliver an 8-minute live demo and 5 minutes of Q&A in front of everyone. That's your moment. Your pre-flight is light because most of your work happens on the day — but the half hour you spend before April 17 thinking about your value prop and your opening line is the difference between a confident pitch and a fumbling one.

Checklist
By April 16

Five items. Total time investment: under an hour.

  • 01

    Read the spec end to end

    Twice. The first read is for content. The second is to find the moments — the visual demo moments the Builder can produce that will land in front of the room. Note them down. You'll ask the Builder for them in Discovery.

  • 02

    Draft a 30-second value prop in your own words

    Don't memorize the spec's pitch. Write your own. "This is a thing that does X for Y, and here's why a buyer would pay." Three sentences. You will iterate it on the day, but bringing a v0.1 means Discovery isn't starting from a blank page.

  • 03

    Understand the demo arc shape

    Slide 1 (intro, 30 sec) → live demo (~5 min) → comp slide (1 min) → pricing slide (1 min) → close slide (30 sec). Total: 8 min + 5 min Q&A. The Market Analyst owns the comp slide. The Pricing Strategist owns the pricing slide. You weave them in. The Builder runs the live tool silently while you talk.

  • 04

    Block 15 minutes to think about how you'd open

    The first 30 seconds of the pitch matter more than the next 7.5 minutes combined. What's the line that makes the room lean in? Bring a draft. You'll iterate on it during Polish.

  • 05

    Acknowledge recording consent

    Every working session is recorded. Your Discovery contributions get captured. Your final pitch gets captured. Both are reference material the firm will reuse.

In your head
What to bring

Polish is your block, not the Builder's.

From 3:15 to 3:45 PM on April 17, the Builder freezes code and you take over. You rehearse the full pitch on the live tool. The Builder is silent. The Market Analyst and Pricing Strategist have already handed you their slides. You own the room during Polish — that's the moment you turn into a presenter.

The demo IS the slide deck.

The four supporting slides exist only to frame the live tool. If you find yourself spending pitch time on slide content instead of the running app, you're doing it wrong. The rule from the Build Day brief stands: must show the thing.

Q&A is performance, not anxiety.

Five minutes of Q&A after the demo. The Client Advocate, Market Analyst, and Pricing Strategist back you up on questions in their domains. You don't have to know everything — you have to know who knows what and pivot to them confidently.

Recording

Every working session is recorded. Your live demo and Q&A are recorded too — and they end up on the prototypes page as part of each prototype's permanent record. Treat the demo like it's going on a portfolio. Because it is.
