The Selective Tweets app I created for Facebook has been used by over 1.3 million people - I wrote about it here: http://bit.ly/selective-tweets-story
I founded membership management platform GroupSpaces, and grew it to help thousands of group leaders manage 5 million memberships, raising $2.5M investment along the way.
I was Facebook's first international hire for Growth Marketing, where I led Growth Marketing for Workplace by Facebook.
I've had in-person 1:1 mentoring/advice sessions with over 300 startups and counting, and love every one I do.
Describe the most impressive thing you've done.
