Just give yourself a month and don't write a single line of code.

Go meet your customers in the first week. Ask lots of whys. Do more structured IN PERSON interviews in the second week. Look at how it has been solved in the past and what competitors do. Draw up a rough solution (e.g. landing page) in week 4 and test it out in person as well as drive some traffic to it from online communities (reddit and FB groups do get you some traffic to have an idea about conversion rates).

GV has some good articles around cust dev interviews on their medium.

You probably have higher chances finding angel money for a well validated idea in the market than a product you built for 3 months full time without knowing exactly what to build.
