Incase you stumble upon a VC, here is a list of questions that can help you use their knowledge/expertise/insight for your products long term vision and validation!
1/Does your experience tell you [your-product-name] is a unique solution?
2/Do you think the idea will be accepted?(a)by people b)by investors?)
3/Are you convinced by the idea and ready to risk loosing your investment? 🙂
4/What are the areas that [your-product-name] needs to specifically work on?
5/What is the suggested milestones/checkpoints you recommend that are
important post launch/before/beyond?
6/Do you think [your-idea-name] needs investment/funding/backing?
7/Does [your-product-name] need to rush the idea to the market?
8/Is it ok to go for an [country-location-name] only launch for now?
After this form of scrutinizing is over, ask the VC to take off their hat and give feedback about your product as a normal user(if they have the capacity to be your products consumer).
Hope this is helpful to anyone reading it 🙂
