AI prompts for founders — from idea validation to investor decks
Founders wear every hat, which means they also write everything: pitches, landing pages, investor emails, hiring posts, legal summaries. AI is the best tool for getting a strong first draft fast — but only when the prompt is specific. These templates are designed for the real problems founders face every week.
Top prompts for founders & entrepreneurs
1. Validate a business idea
"Is my startup idea good?"
Too vague—AI has to guess what you want
"Act as a sceptical but fair VC analyst. Evaluate this startup idea: [idea]. Cover: (1) whether the problem is real and who has it, (2) market size (is it big enough to matter?), (3) top 3 risks and how fatal each is, (4) existing competitors I may not know about, (5) a stronger version of this idea. Be direct. No encouragement padding."
Specific, clear, ready to use
2. Write a landing page
"Write my landing page"
Too vague—AI has to guess what you want
"Write landing page copy for a B2B tool that automates expense reporting for freelancers. Structure: headline (under 10 words), subheadline (one expanding sentence), 3 benefit bullets (outcome-led, not feature-led), social proof placeholder, and CTA button label. Core pain point: manually tracking expenses wastes hours every month. Tone: practical and empathetic."
Specific, clear, ready to use
3. Create a pitch deck outline
"Help me make a pitch deck"
Too vague—AI has to guess what you want
"Create a 10-slide pitch deck outline for a pre-seed SaaS startup targeting HR teams. Use the standard VC framework. For each slide: the one key message, the main visual or data point to include, and one question an investor is likely to ask. Flag the 3 slides where founders most commonly lose investor interest."
Specific, clear, ready to use
4. Write an investor update
"Write my investor update"
Too vague—AI has to guess what you want
"Write a monthly investor update email. Metrics: MRR £22k (up 9% MoM), 3 churn events (2 budget-related), 2 new pilots signed with Fortune 500 companies. Structure: metrics table, 3 highlights, 1 honest lowlight, focus for next 30 days, one specific ask (warm intro to X type of company). Tone: transparent and confident."
Specific, clear, ready to use
5. Brainstorm growth experiments
"Give me marketing ideas"
Too vague—AI has to guess what you want
"Generate 10 low-cost growth experiment ideas for a B2B SaaS tool with 80 customers and £12k MRR. Focus on channels we can test in under 2 weeks with under £500. For each experiment: hypothesis, how to run it, success metric, and estimated effort (high/medium/low). Prioritise experiments most likely to find product-channel fit."
