Starting a startup is a sign of being fearless. As a founder, you have to ensure that this philosophy gets propagated in every aspect. The hierarchy or pedigree should not hold back radical transparency.
A fresher should get an equal opportunity like anyone else. They will be wrong at times. Encourage them to learn and grow. Their fearlessness will foster creativity and innovation.
Creativity and innovation come with independence. To be independent, one has to be fearless.
