Most of these intertwine/are connected. You fix one, you’ll automatically fix others.
In my experience, the founder needs to hire a marketer, whether fractional or a CMO, to get their messaging and ICP dialed in.
I’ve helped 2 SaaS companies with much of this. I had to read their sales decks and speak to the sales teams to get good answers about the selling points, pain points, and framing of the product. It’s a lot of work to untangle the industry jargon and determine how to talk about the product if it’s a new solution or technology that people don’t know about.
Most of the time you have to target people looking for the existing solutions.
