Ultimately, every investor is different. However, when looking to invest in any startup company, there are a number of boxes you will need to check regardless of who decides to invest in you.
You need to know the market. How big is the market? How populated is the market? Is your product or idea doing the same as every other product on the market? How does your product stand out in the existing market? What sets it apart?
Having a strong business plan is essential. No one will want to back you if you do not have a solid plan for the future. Investors will want to hear numbers and forecasts. They do not want to hear you say that there are no risks involved, or hear you answer every question with certainty that no problems will arise because that is unrealistic. They will want to hear how you plan to tackle problems as they arise.
Investors will need to believe in you. You need to be sincere. Are you positive? Are you flexible? Are you realistic yet ambitious? Can you talk to people? Are you a good leader? A good listener? Do people respect you?
The team that you have on board will also be considered. Your team needs to live and breathe the product or idea just as much as you do. Do they listen to and respect you as their leader? As a collective, do they have sufficient skills and expertise?
Investors meet with numbers of founders and will get a gut feeling about you and your idea, but being able to address the above-mentioned areas should truly set you apart.
