He was involved in an anarcho-futurist collective in La Spezia which he led (along with Auro d'Arcola) to be active in the militant anti-fascist "Arditi del Popolo". He was close friends with Enzo Martucci and Bruno Filippi. Renzo Novatore wrote for many anarchist papers ("Cronaca Libertaria, Il Libertario, Iconoclastal, Gli Scamiciati, Nichilismo, Pagine Libere") where he debated with other anarchists (among them Camillo Berneri). He published a magazine, "Vertice", which has unfortunately been lost apart from few articles. Novatore collaborated in the individualist anarchist journal "Iconoclasta!" alongside the young stirnerist illegalist Bruno Filippi.
