If it is a securities company, then the marketing department is to pull customers to open accounts for stock trading. Then we have to sell collective wealth management products, funds and so on.
If it is an asset management company, is it a private equity company? That is to sell private products. It may also be a trust company that sells trust products.
Because you didn't say anything specific, and I'm not sure.
In short, it should be looking for rich people to buy wealth management products or stocks.
