Your first hurdle will be how you handle money.

Since many banks refuse taking deposits from any cannabis related business, first choose a state + bank which will allow you to make deposits.

Simply resolving this issue first, will put you in... probably <1% of people who think about this before hand.

And this is the first question any sensible investor will ask.

So if you just solve this problem, you'll likely have access to a much larger pool of investor money than competitors.

Also... You don't really require investors.

Just start with paid traffic - Gemini, Outbrain, Taboola.

This way you'll keep 100% of your company + make money just as fast, as you'll be buying traffic to sell your product anyway.
