This article reports on a study of 65 randomly sampled medical crowdfunding campaigns and five interviews with campaign authors. We found that authors innovated technical and professional communication (TPC) tools to narrate their illness experiences, coordinate digital audiences, and compel action. Thus, these authors practice TPC as care seeking and caregiving. Crowdfunding platforms, however, situate authors to individualize structural problems in ways that preempt collective action. We conclude with pedagogical implications of our findings.
