I have an unpublished blog post on this very subject so I&#x27;ve done a bit of research into the matter.<p>I first thought Pinterst was the first one to extend the exercise period to a great length, but I discovered that it was in fact Quora who was first. They have a 10 year exercise period. Pinterest was followed by Coinbase.<p>First time founders will have a hard time rocking he boat because of the great fear of not being able to raise capital. Thus it&#x27;s really on the shoulders of the late stage companies and repeat founders to lead the way.
