I think the courses definitely have a market. I’d probably push more ‘benefit’ into your headline/subhead, and target the specific customer very carefully.
E.g. by “growth” you’re meaning growth hackery, not “scale my startup”. Your front-page copy should probably more explicitly say that, to exclude the SaaStr.com crowd and focus more on the people you want, who will then be able to say “yup, this is for me!”
The headline “The Go To Place To Learn Growth And Tech” is likely something you can make more punchy. You need a headline that stops budding growth hackers dead and makes them need to read the rest, immediately. This might help? It’s part of a series so you can get just that one or the whole bundle.
Gawd, I’m so going to get banned for talking about growth hacking. I better stop now.
