Side question about the private beta signup:

Are you trying to restrict signups to USA-only, or did you just not take international users into consideration when writing it?

Either way, just signed up and filled in my American cellphone number (which only works when I'm actually in America, which isn't that often) and entered my UK number in the one box that allowed me to write any sort of prose. If you're currently excluding international users, feel free to disregard my application :)


sorry about that!

Try signing up again in a few minutes. Or email us directly at dbeyer@chart.io


I see you've changed the phone input now, great! Not that it makes any real difference to the signing up, but just for the sake of appealing to international users, "State" could possibly be called "State (within US) or Country (international)" or something similar.

I won't sign up again as I did submit the form before, but good to see the change for future people :)


“An evidence snob is not someone who “want[s] evidence that something works.” An evidence snob is someone who disregards evidence — evidence that doesn’t reach a sufficient level of quality.”

This is a really significant notion.

It's basically saying what you see in old martial arts movies: listen to all your senses.


@chart.io home page. Have you tried A/B testing a red instead of green sign up button?


I'm inclined to think the red will generate a better conversion.


Red does generate a higher conversion, at least on add to cart buttons. I have personally a/b tested this at my day job and the conclusion was red (by a landslide). We tried green, orange, blue, and red.


Thanks for the confirmation! What was the site's background colour?


The buttons were against a solid white background. It was also the only test we ran at the time to ensure that we weren't blowing the test results. I think the entire composition of the page matters though. Conversion rates for an element don't necessarily cross-over to a completely different layout, so testing is always still a good option.


I don't think that's even worth A/B testing. The red is much better! Even purely from a design perspective. It makes it more vibrant. Thanks for the suggestion.


nope. Good idea.
