Depends on where you're starting from. Is sales something you've done previously and you're currently doing with some success but want to be better? Or are you a technical founder who doesn't feel comfortable selling but want the challenge and know you can be great at it, if provided the support? Or something else entirely?

There is no one formula, despite what the publishing and coaching industry says!

I'd encourage you to re-post or edit the question with more details so I can answer it in more detail, or I'm happy to a call with you to understand what you're looking to achieve and provide you some suggestions.
