Answer
Having investment experience is not a requirement to start a role as a VC scout.
So for example you don't need to have a history of investing your or other people's money in startups. It is also not necessary to have invested in other types of asset classes like public company stocks, cryptocurrencies, property, etc. In fact there is no requirement on personal wealth.
On the other hand, one key criteria that is much more important to have than investment experience is to have a good feeling for what makes for a good startup as well as a network of quality startups, usually at an early stage, to refer to investors.
