The verdict
For a small B2B team that wants a company website it can grow, I'd pick Webflow. Every B2B site I manage today runs on it. I can build campaign landing pages in hours, the CMS handles content marketing well, and the Editor mode lets colleagues change copy without breaking the design.
If you only need a page to test an offer or collect sign-ups, pick Carrd. It is live the same day and costs very little to be wrong with.
The honest cost of Webflow is the learning curve. A marketer with no design background will need training, or an agency to build the structure first. If you cannot invest that time yet, start on Carrd and plan the move. Carrd's own limits, one page per site and narrower design control, make that move likely once the idea works.
