Nozbe is a task and project management app built explicitly around GTD and async teamwork — designed by Michael Sliwinski, a dedicated GTD practitioner who built the tool he needed for his own distributed team. Founded in 2007 and rebuilt as Nozbe Teams, it emphasizes tasks as the primary communication medium rather than chat — projects and comments live on tasks rather than in separate message threads. For remote teams committed to async-first work culture, Nozbe's philosophy of task-centric communication reduces meeting overhead significantly.
