Content
what if we could then dynamically Niche so instead it's like they are getting a email that I send about the course and then if they're a Creator maybe I put the quote from Dickey push of ship 30 because he's a Creator and if they are a consultant maybe I put the quote from... they've used their clients to like make to basically they've taken what I've taught them and built a really good little personal freelancing or agency business

Dynamically niche by swapping testimonials, not pages

Niching always wins, but running "Mastering ConvertKit for SaaS" AND "...for Book Authors" AND "...for Consultants" is insane. Keep one product page/email and conditionally swap the testimonial, case study, or single benefit paragraph based on what the visitor told you. Cheapest form of dynamic niching, and it's why generic "works for everyone" copy converts worse than either targeted version.

Distribution
my second book The embedded entrepreneur dives into a smaller part of this journey starting a business by understanding the needs the challenges and the desires of a community that you're already part of or want to be part of

Embed in a community before you build product

Audience-first founders start by joining a community they genuinely care about, learning its language, problems, and inside jokes long before pitching anything. Show up consistently, contribute value, and let the product idea emerge from observed pain — not the other way around. Your audience and your first customers should be the same people. (Arvid Kahl, The Embedded Entrepreneur.)

There's a play for whatever you're stuck on.
