Who started ICO?

Could you please elaborate on the origins of Initial Coin Offerings (ICOs)? Who was the pioneer in launching this innovative fundraising mechanism within the cryptocurrency and blockchain industry? Was it a single individual or a team of visionaries? I'm curious to understand the background story and the motivation behind this groundbreaking initiative that has revolutionized the way start-ups and projects raise capital. Your insights into the early days of ICOs would be greatly appreciated.
