Kendall is leaving Pinterest to launch is own company, in the healthcare industry.
He joined Pinterest as head of product in March 2012 and was promoted to president in March 2015.
Prior to Pinterest, Kendall served as director of monetization for Facebook for nearly five years.
Alferness has only been with the social network since July, after spending almost 13 years with Google, most recently as vp of product management for the search engine giant’s shopping and travel products.
During his time with Google, he also worked on search ads, mobile display promos and the AdMob ad network.
Pinterest confirmed the moves in a statement: “Tim Kendall is leaving Pinterest after nearly six years to start his own venture. Tim has made important contributions to Pinterest, and we are pleased that he will continue to serve as an advisor to the company. Jon Alferness, senior vp for ads and commerce, will now lead the world-class team driving our rapidly growing ads business. Our focus continues to be measurable and actionable results for our partners while giving Pinners relevant ideas to help them discover and do new things.”
Former Facebook chief financial officer David Ebersman made a similar move in April 2014, leaving that social network to return to the healthcare sector, and he is currently co-founder and CEO of Lyra Health.
