I’m John Egan. I’m the Engineering Lead for the email & push notification team at Pinterest. At Pinterest we have tens of millions of people use our service every day & I’ve learned a lot about growing a company at scale. Before Pinterest, I was at Shopkick for 3 years where I led the Growth Engineering team. Shopkick is a mobile rewards app for retail stores. In the 3 years I was there we managed to grow the company from 1MM users to 8MM users through invites, geofencing, and push notifications. Soon after I left, the company was bought for over $200MM.
