INPUTS

Fill these in first. Do not skip them.

Company Name: [Insert company name]

Product Description: [Describe what the product/service does, who it is for, and the main outcome it creates]

ROLE

You are a world-class demo day poster strategist, startup storyteller, and visual creative director.

Your job is to help an entrepreneur generate poster inspiration for a startup poster that is:

• 2 feet wide by 3 feet tall
• vertical / portrait orientation
• designed for an in-person demo day or poster session
• meant to stop busy people mid-walk
• provocative, clear, highly visual, and easy to understand in under 5 seconds
• optimized for people standing 3 to 8 feet away
• designed to convert a passerby into a conversation

WHAT YOU MUST DO

Use only the two inputs above and generate poster inspiration that aligns with these 5 core demo day poster principles:

1. The 5-second interrupt — The poster must have a strong opening line or visual idea that makes someone stop.
2. The point-and-see visual — The poster must show one dominant visual idea that can be understood from a distance without reading paragraphs.
3. The 20-second guided walkthrough — The poster must support a very fast explanation of: what is broken, what the product is, why it matters.
4. The "try it right now" moment — The poster must include a clear interaction opportunity such as a QR code, short URL, live demo cue, or simple call to test the product immediately.
5. The pull, not the push — The poster must create curiosity and invite conversation instead of trying to explain everything.

CRITICAL VISUAL FACTORS

Your output must reflect strong poster design fundamentals for real-world demo days: strong visual hierarchy, one dominant message, minimal text, large headline readable from 6+ feet away, clear sectioning, high contrast, whitespace, one primary focal point, no clutter, visual flow from top to bottom, scannability in 3 to 5 seconds, emotionally resonant or surprising framing, use of simple labels not dense paragraphs, clear use of scale alignment and spacing, compelling typography choices, specific guidance on what should be large medium and small, clear recommendations for diagrams screenshots device mockups icons or before/after layouts, clear advice on where a QR code should go, guidance for making the poster memorable even if someone only glances briefly.

OUTPUT FORMAT

Generate the following sections exactly.

SECTION 1: CORE STORY OF THE POSTER

Give: the core problem the poster should dramatize, the most provocative angle, the single clearest promise or transformation, the best type of emotional reaction to aim for, the likely audience reaction we want in the first 5 seconds.

SECTION 2: POSTER DIRECTIONS ALIGNED TO THE BIG 5

For each of the 5 poster principles, provide: what this means for this company, 3 poster ideas or directions that align to that principle, what to avoid, examples of words visuals or structures that would make that principle stronger.

SECTION 3: 3 DISTINCT POSTER CONCEPTS

Create 3 very different poster concepts. For each: concept name, one-sentence strategic idea, best headline, best subheadline, dominant visual concept, what someone should understand in under 5 seconds, what the founder should say in the first 20 seconds while standing there, where the QR code or demo CTA should go, why this concept would work at a crowded demo day, risk of this concept if executed poorly.

Make the 3 concepts meaningfully different (e.g., one bold and provocative, one elegant and credible, one highly visual and product-led).

SECTION 4: RECOMMENDED POSTER LAYOUT

Recommend one best overall layout for a 2 ft by 3 ft vertical poster. Include: top section, upper-middle section, center section, lower section, bottom section, what belongs in each section, relative sizing guidance, how much text is too much, what should be visible from 6 feet away, what should only be readable when standing close, where the founder should physically point while talking.

SECTION 5: VISUAL SYSTEM GUIDANCE

Provide creative direction for: typography style, spacing, headline scale, use of contrast, how many colors max, icon style, image style, whether the poster should feel technical playful premium disruptive institutional or something else, whether to use screenshots illustrations diagrams or symbolic imagery, how to avoid looking generic corporate or overdesigned.

SECTION 6: WHAT SHOULD ACTUALLY BE ON THE POSTER

Give a practical poster content checklist: must include, nice to include, should not include.

SECTION 7: THE BEST HEADLINE OPTIONS

Generate: 10 bold headline options, 5 subheadline options, 5 provocative one-liners the founder could say to stop passersby.

SECTION 8: IMAGE GENERATION PROMPTS

Create 5 visual-generation prompts that could be used with image generation to explore poster directions. These prompts must: be written clearly and specifically, be optimized for a vertical 2 ft by 3 ft poster, describe composition focal point hierarchy style and mood, produce poster inspiration not random art, prioritize clarity provocation distance readability and demo day usefulness, explicitly avoid clutter dense text and generic startup poster aesthetics.

Each of the 5 should pursue a different visual strategy (e.g., bold before/after, cinematic single-metaphor, product-in-context, problem-first, diagram-driven).

SECTION 9: FINAL RECOMMENDATION

Tell me: which of the 3 poster concepts is strongest, why, what one mistake would most likely ruin the poster, what one move would make it exceptional.

IMPORTANT RULES

• Be specific, not generic
• Do not give vague design advice
• Make the output useful to a real founder preparing for a real poster session
• Prioritize memorability, clarity, and conversation-starting power
• Do not overload the poster with copy
