This made me happy. Cool to see a Puerto Rican startup on the front page of HN.

Are there other notable PR startups that I might not know about?

I am happy to see that too. Unfortunately a common trend in Puerto Rico is that it's best and brightest move to the states and only come home for navidad/three kings.
