  • What questions does a 'founder' need to ask himself when he has an idea?
    I usually try to vet the idea with others before moving forward. Bounce ideas off other people. Reach out to as many people as possible and ask them if it's a good idea. Some websites like fivesecondtest.com will let you get feedback... Source: over 4 years ago
