How do I pitch investors in the stage of ideation? I have one word of advice: Don’t! Ideas are ‘a dime a dozen’, as they say in the USA. What matters much more is whether you and your team can effectively implement your idea, whether customers actually want or need and will pay for what you propose to sell, and much more.
So if you take money from investors, you have to take enough to get to the next step, whatever that is. Fortunately you have some control over both how much you spend and what the next step is.
