Hi sama,<p>First of all, thanks for the 10 million dollar donation for YC research.  That&#x27;s an amazing gesture, and I&#x27;m really looking forward to seeing the scientific research model get completely disrupted - it&#x27;s in a terrible state and it needs a big shove.<p>- Given your donation, what are your thoughts on philanthropy?<p>- Most of your advice is for founders, however, what should an employee look in an early stage start up when deciding whether to join?  Obviously, the decision is much easier if the company has started growing exponentially, but before that?
