Stewart Butterfield, San Francisco. January 2016.

Stewart cofounded two super impactful and meaningful companies, Flickr and Slack. I am a subscriber to both products and we are investors in the latter.

A few weeks ago we had our annual meeting with our investors in San Francisco . Stewart spoke at our event and was so very thoughtful about the challenges and opportunities at Slack. But what impressed me the most was just how down to earth and direct he is. Inspiring.
