1. Validate your SaaS idea Most ideas fail because they solve the wrong problem. Prompt: “You are a startup strategist. Validate this SaaS idea by identifying the core problem, target audience, urgency level, and willingness to pay.” → [Insert your idea]

2. Define your ideal customer You need to know who you’re building for - not just what. Prompt: “Create 3 ideal customer profiles (ICPs) for this SaaS product. Include job title, industry, daily pain points, and buying behavior.”

3. Analyze the competition Before you build - know what already exists and where you can win. Prompt: “Compare [Your SaaS] with [Competitor A] and [Competitor B]. List strengths, weaknesses, pricing, and positioning. Suggest one unique differentiator.”

4. Generate a clear value proposition Confused pitch = no traction. Prompt: “Write a clear, one-sentence value proposition for this SaaS product. Use the formula: [What it does], [Who it’s for], [What outcome it drives]. Then rewrite it 3 more ways with different tones.”

5. Plan your MVP features Don’t overbuild. Ship fast. Learn faster. Prompt: “List every possible feature for this product. Then prioritize using MoSCoW: Must-have, Should-have, Could-have, Won’t-have.”

6. Write your SaaS pitch deck outline Need a deck to raise, pitch, or align your team? Prompt: “Act as a SaaS founder. Create a 10-slide pitch deck outline for [product name]. Include what goes in each slide: Problem, Solution, Market, Product, Traction, Team, etc.”

7. Map your go-to-market (GTM) strategy It’s not just what you build - it’s how you distribute it. Prompt: “Act as a B2B SaaS GTM strategist. Outline a go-to-market plan with: → Launch channels → Ideal content formats → Early user acquisition tactics → First 3 months

8. Write your homepage copy Your homepage is your 24/7 sales rep. Prompt: “Write homepage copy for a SaaS that helps [audience] solve [problem]. Include a headline, subheadline, feature bullets, CTA, and objection-handling section.”

9. Forecast your growth & revenue Investors love clarity. AI helps you model scenarios. Prompt: “Forecast user growth and MRR for this SaaS product over 12 months. Assume $X price, Y% churn, and Z new users/month. Include a basic growth table.”

10. Create a 30-day founder action plan Planning is good. Execution is better. Prompt: “You are my SaaS cofounder. Give me a 30-day action plan to go from idea to MVP launch. Include weekly goals, tools to use, and time estimates for each task.”

You don’t need to wait for the “perfect time” to start your SaaS. Gemini can now: → Think like a strategist → Write like a founder → Plan like a PM → Pitch like a pro You just need a clear idea + the right prompts.

@Yesterday_work_ These prompts are a full startup toolkit, validation, GTM, pitch deck, even revenue forecasting. Love how you’ve made the entire founder journey plug-and-play with AI.

@Yesterday_work_ The biggest unlock here is speed. What used to take weeks of research and consulting… Now takes 30 minutes with a well-structured prompt.

@Yesterday_work_ Investors don’t want fluff. They want clarity, traction, and a roadmap. These prompts get you all three before you’ve even built.

@Yesterday_work_ This thread is basically YC office hours in prompts.

@Yesterday_work_ The “30-day founder plan” might be the most valuable. Execution beats inspiration every time. This keeps you moving when most people stall.

@Yesterday_work_ Valuable prompts are indeed assets. A hundred dollars might underestimate their potential worth. Consider the ROI they could unlock.

@Yesterday_work_ Most founders overbuild their v1. This MVP prompt forces discipline from day one.

@Yesterday_work_ ICP prompt alone can save founders months of guessing.

@Yesterday_work_ AI just became the cofounder you don’t have to give equity to.

@Yesterday_work_ Include target customer segments, channels, and key metrics for success.”

@Yesterday_work_ The GTM mapping is gold. Distribution beats product every single time.
