Interesting, apparently today is steal-someone-else's-comment-day.

In this particular case the short answer is no. The long answer is also no.

Outside of a logo, colors and typographic layouts and image stylings can't be copyrighted...and for good reason. Aesthetics is dictated by broad cultural trends, so to claim any of it is "original" is naive at best. A general rule of thumb (with exceptions of course):

You can own the rights to the function but not the form.

Or in the context of a website you can own the content but not the layout/styling of it.

The exception is in things like logos where the form is the function, i.e. to serve as a corporate identifier. It's why you can make a replica of a Gucci handbag design and sell it at H&M as long as you don't stick the Gucci logo on it. Since any patent that ever existed on the concept of a handbag itself (i.e. the function) has long since lapsed, and the form is largely dictated by trend, you don't see many successful handbag lawsuits unless logos are involved.

If studiobinder was telling people they are an invision product (e.g. They slap the invision logo in their navbar), then it would be illegal. It'd be almost impossible to make the case otherwise, seeing as the invision design is a really generic landing page.

Just wanted to say there's a lot of value in hiring a firm to build an outsourced “MVP as a service” (I've done it on contract plenty of times), and 30 days isn't crazy if you know where to spend your team's time (but I'm sure you know this).

However it's kind of crazy that someone would go this route, given that you can buy a template of comparable quality for $10.
