I would start by developing a pitch deck / document that outlines the following:
– what you do
– example of your tech
– size of total addressable market (TAM)
– your competition
– your unique selling proposition (USP) aka your secret sauce
– your traction / customers
– your model
– your revenue to date
– your team
– your plan to spend funding and return expected
Most investors look for a company that has some kind of traction, customers, and revenue. If you’re able to secure a small business loan or funding from friends and family to start your website, then you’ll be more likely to be able to secure investment in my opinion.
Do you have a website, or a documented business plan?
