Yeah, after you mentioned it, I put ours side by side with stipe, and yeah, they look alike. Not like we tried to do that or anything. We are way more focused on the editor and making sure that works well.
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.
