Great idea, but the problem here is that what works somewhere, doesn't work elsewhere and it's all about testing.

But testing multiple fields, with multiple variables and experiments requires lots of traffic.

And what works for one source of traffic, PPC for example, won't duplicate to other sources of traffic like TV / Radio / PR / SEO / etc.

We recently ran a ton of traffic just around an inbound-email newsletter pop-up that lists out what we found to work best here:

Those are some "tried and true tips" that we'd stand behind for a popular affiliate marketing blog getting most of their traffic via SEO and referral, but unfortunately the entire addressable universe that we can guarantee those results for are the client we undertook the project with ;)

Which is why I think it would be an interesting startup.

The base case alone would be enough to get many to buy your component but for a subscription (where the real money is) you need to provide continuous value.

So your pitch could be that using your product would instantly get you the best industry standard input forms but over time they'll get better because you're going to apply a/b testing and machine learning on them continuously.
