Constructive Feedback from a small timer / upstart:
The ability to just swap out the logo on the CMS if you are on a personal plan while leaving the Webflow bits in the code & forms would have been nice. Cool feature but can't/won't use it at that cost - but you probably already know that given your statement above.
Explaining the features & ease of use that comes with the cutting edge technology of the CMS and level of hosting is worth the "extra" cost of hosting per month in a client's eyes (most are typically used to sub $5 USD) - so the jump to $10 seems like money well spent.
Convincing them to jump to $15 or $20 a month (depending on what plan you are on) just so I can slap my logo in the bottom left corner would be much harder, especially if you are simply being transparent about where their money is going: $5 for super awesome hosting, $5 for super awesome CMS, $10 for me to slap my logo in the bottom left corner of the dashboard...
Nobody really has a problem with their clients knowing they are using Wordpress for the CMS, so what's the difference in the end. I've realized that it doesn't really matter if I tell my clients I use the Webflow platform or not. They aren't UI designers who are proficient in all the skills needed to deliver a web project (html, css, hosting, etc...).
I know your landing page verbiage sounds like "sign up now, anybody can do it" but we all know that isn't necessarily the case. As previously noted, some small business owners will try to work through their way through it, but you have to have a specific level & combination of technical know-how, designer skills, and proficiency in html/css to be able to do nice things with Webflow & create anything your mind comes up with. Sounds like a skill set that people are willing to pay for to me, no shame in telling people I'm using Webflow to accomplish it. They just want a beautiful & responsive extension of their brand that works, so they can focus on building their business & not trying to be a designer or a developer.
However, I do think you guys have to find a way to get beyond the "hey, this new feature is coming soon..." then dropping it months later and saying "here it is!!! it will only cost this much more!".
That is always going to rub your client base the wrong way, so every single time you do it - expect blow back. People in general were used to buying software to use, now the world has shifted to SAAS and subscription plans... Adobe championed the model, so people feel like they are already paying you for new features, continually/endlessly every single month. Especially on this platform where you get your Webflow tool fee & now the hosting fees via the clients they bring you.
I love Webflow, I hate surprises, white-labeling is cool if your clients are fine with paying you $20+ for hosting alone & this still leaves you with some kind of monthly maintenance/update fee wiggle room if that is a necessity in your business model. If so, good for you, hope to be there one day Until then, I have no problem with the Webflow logo sitting in the bottom left corner.
