Podcast host Peggy Anne Salz catches up with Esther Hwang, Director of Growth at Poshmark, the largest social marketplace for fashion, to discuss how she identifies new web and mobile channels with the most potential, and architects ad creatives with the most impact. Do you need to be a hacker at heart to succeed in data-driven mobile marketing? Esther talks candidly about the skill set you need to reach your acquisition and engagement targets, and shares how her own education in the arts has equipped her to step back and view the “Big Picture” of campaign performance.
