I am looking for recommendations. My startup's website is currently built with Contentful on the backend and Next.js on the frontend. I can see the potential for this stack for a large Enterprise but find it cumbersome for a small startup. In our earliest days I was using Squarespace which was fine at the time but problematic for lots of reasons as we have grown.I am wondering if there is something that is closer to Squrespace but offers the ability for deep customization.Some examples of the type of website I am looking to put together are:
