Daily Prompt Pack: ideation and validation – validate your startup idea before you build

Most founders build first and ask questions later. These three prompts flip the script so you spot red flags before they become expensive mistakes.

[Claude]

I have a startup idea: [describe your idea in one sentence]. Act as a skeptical VC and run a 5-point validation teardown: market size, competition intensity, revenue model clarity, founder-fit score, and timing risk. Return a scorecard table with a 1-10 rating per category and a go / no-go recommendation.

[ChatGPT]

Given my startup idea [describe it], generate a 10-question customer discovery interview script. Each question must move from broad problem awareness to specific willingness-to-pay. Output the script in a numbered list with suggested follow-up probes after each question.

[Cursor]

I am building [describe your product] for [target customer]. Write a Python script that scrapes public Reddit threads and Hacker News comments for pain points related to this problem. The script should extract the top 10 recurring complaints, count frequency, and export a CSV with columns: source, quote snippet, upvotes, and urgency sentiment.
