Marc Andreessen famously believes that there’s no such thing as an original idea. So you gain a lot of credibility if you are able to see what other potential competitors you have. Yes, they may not he direct customers but they exist in the same use case. For e.g. Playstation competes with Netflix. How? Because I have spare time, it’s either I watch Netflix or I play PlayStation. Although something like Disney + is a direct competitor to Netflix, you have to look deeper than that
