Hi! I’m Jeff Chang, a Tech Lead on the growth team at Pinterest. I’ve worked on a few different growth channels to help Pinterest grow to 250MM MAU. I also advise and invest in a few awesome startups. Some startups that I work with include Upwork and Apartmentlist.

I have experience in:

  • Building a high impact growth team - As an early member and leader on the growth team, helped build a data-driven and impact focused culture, implemented technical and operational solutions to increase impact, and mentored high performers.

  • SEO - ran many SEO experiments to increase Pinterest traffic by millions a week

  • Authentication - Led an initiative around inventing new login mechanisms and optimizations to increase our weekly active users by tens of millions

  • User Engagement - with PM and design, led an effort to increase pin impressions, which substantially increased engagement and revenue

  • Mobile acquisition - created and executed mobile acquisition strategies, increasing our daily mobile signup and app install numbers by 2x in one year, without any paid acquisition. This also brought Pinterest into the top 20 of the US app store ranks

  • Conversions - Optimized unauth pages all over Pinterest to increase daily web signup rate by many multiples

  • Web Performance - Rebuilt the unauth landing pages from scratch to decrease page load times by 40%, and increase signups and traffic significantly
