Pesky gNATs is designed and developed by Handaxe CIC, a not-for profit Community Interest Company founded by David Coyle and Gary O’Reilly. We believe technologies that support adolescent mental health interventions can make an important contribution to society. But only if they are widely available. 
Gary gave at talk at TEDx in which he spoke about Pesky gNATs and our vision for widely available technology. He asks how generous should we be with technology based mental health interventions? Is it possible to make them available at little or no cost, sharing not just our ideas, but also sharing technology that allows us to promote good mental health in children.
