I would try to make up some slides to show what an investment marketer does (I have no idea what you do!)
Google Job Description. Source for new investors and expansion of portfolios from new and existing clients. Evaluate structure, negotiate, and close new transactions, portfolio restructurings, rescheduling, capital increases, equity sales, etc. Relationship management of existing and new investors.
So a slideshow with a person who has started a company/invented an idea or something, and needs money for something (to grow, market, manufacture), needs help to get money, so you help them. Then explain what you do to help them - go and meet people with money and want to make more, help them make their idea look better etc. Very high level and lots of pictures.
Maybe explain day to day what you job looks like - meeting clients, looking for investors, working on a computer with emails, zoom calls, graphs and data to work out answers to big numeric problems etc.
