To be honest and having been there before you, it's not a good idea. You entered a crowded space with a product that do not yield blatant differentiation. Your marketing, brand image and storytelling are the only things that will lead users to your app.

I don't think web developers will elect a newborn CMS, trust that it doesn't fail for the 5 or more years, if you don't convince them your CMS and the company behind it is future proof. And on that matter, your landing page and your documentation matter more than everything else. Invest time and money in it.
