Who was Instagram's first Community Manager, joining in October 2010?

Instagram's first Community Manager was Josh Riedel, who joined the company in October 2010. His arrival came during Instagram's earliest growth, shortly after the photo-sharing app launched for iPhone.

Riedel was one of Instagram's first employees and helped build relationships with the community forming around the new service. At that stage, community management involved communicating with users, understanding how they used the product, and helping shape Instagram's public voice.

The timing can cause confusion because several early employees joined soon afterward. Shayne Sweeney joined in November 2010 as an engineer, while Jessica Zollman joined in August 2011 as a Community Evangelist. Those roles were important, but neither person was Instagram's first Community Manager.

Instagram itself grew out of Burbn, an earlier location-based social application created by Kevin Systrom and Mike Krieger. The streamlined Instagram app debuted in October 2010, making Riedel's appointment part of the company's foundational period rather than a later expansion.
