The group was formed by Cameron Kasky and his school friends in the first four days after the shooting.[12] The initial three co-founders were Kasky, Alex Wind, and Sofie Whitney.[2][14] On February 15, 2018, one day after the massacre, Kasky met with Wind at a candlelight vigil.[14] Wind stated, "The day after the shooting, we said something needs to happen; there needs to be a central space; there needs to be a movement."[14] After the vigil, Kasky invited Wind and Whitney to his house. Kasky came up with the name "Never Again" while the group stayed up through the night to make plans, and he posted "Stay alert. #NeverAgain" to Facebook.[12][15]
