I love Makeswift and have been a user since the earliest days. No other website builder comes anywhere close to delivering the speed that Makeswift delivers (and I've used pretty much all of them). This includes basic speed like how fast the builder interface runs, but importantly it also includes the UX decisions their team has made that enable you to create great-looking sites really fast with minimal learning curve.
The Makeswift team truly understands the core problems facing those of us who need to quickly and collaboratively ship beautiful (and beautifully responsive) websites. Makeswift has been a critical tool in our effort to test and validate customer segments and product ideas, mainly because it's so fast and easy to iterate on sites and pages. Quickly testing and improving customer-facing content directly and positively impacts our ability to grow faster.
I believe two of the biggest problems early stage startup founders make are 1) not sufficiently validating customer needs/problems and which solutions best map to those problems, and 2) spending too much time building their customer-facing marketing infrastructure and doing it in a way that can't be easily iterated upon by non-technical team members. Makeswift is a super valuable tool in addressing #1, and it's a non-negotiable part of solving #2.
Thanks for building such a great product, Makeswift team!
