The Texas Tribune, a digital news platform founded in 2009, has hired Stacy-Marie Ishmael, a digitally savvy journalist, as its new editorial director, The Tribune’s chief executive said on Friday.

Ms. Ishmael, 35, a veteran of The Financial Times, BuzzFeed News and Apple, will effectively replace Emily Ramshaw, The Tribune’s editor in chief from 2016 until her departure in January.

Ms. Ramshaw and The Tribune’s chief audience officer, Amanda Zamora, left the organization to start The 19th, a nonprofit news site focused on women and politics that is scheduled for a summer rollout.

Ms. Ishmael, who worked most recently as a senior editor at Apple’s app store, said that issues affecting Texas often turn out to be important to the nation as a whole. “Understanding them through the lens of Texas is a good way to understand the overall U.S. political story, or U.S. demographic story, or U.S. justice story,” she said.
