"Tara McGowan is denying that her high-profile liberal firm ACRONYM played a role in the Monday evening caucus debacle, claiming that her firm was merely an investor in the company Shadow Inc., which developed the app at the center of the controversy. But internal company documents, a source close to the firms, and public records show a close and intertwined relationship between Acronym and Shadow. ... Federal campaign finance records show that the Iowa Democratic Party and the Nevada Democratic Party retained Shadow to develop its caucus app. Shadow has also been retained for digital services by Buttigieg’s campaign, which paid the company $42,500 for software-related services last July, and by Joe Biden’s campaign, which paid Shadow $1,225 for text messaging services, last July as well."
