I think this goes back a bit to what personas you are trying to solve for. Many companies have a generic investor presentation on the website.[1] Every professional investor will have access to sell-side coverage and initiations of coverage is basically this (an overview of the company, key drivers, etc.). Retail investors will often have access through wealth managers. And if it went public relatively recently the IPO deck will function as this.
