Axon Enterprise is an American public safety technology company founded in 1993 as TASER International to sell conducted energy weapons to police forces. It has since built a much broader business around body-worn cameras, in-car video, evidence management software and a growing set of artificial intelligence tools that draft reports, redact footage and transcribe interviews, sold to law enforcement, corrections and enterprise security customers as bundled subscriptions. Headquartered in Scottsdale, Arizona and listed on Nasdaq, the company now earns the majority of its revenue from recurring software and sensor plans rather than hardware sales.
