Hi @dimitrieh, thanks for the PR.

@PabloFilomeno83 and I discussed changing the CTA on the website and decided against it at the time, but I’m happy to revisit. My original suggestion was only for the sign-in page, but that worked in combination with the supporting copy (“we’ll guide you through the next steps”). On a standalone button, I think we need something more neutral.

If we’re going to change it across the website, maybe it’s worth considering this experiment from a while ago. Get Started performed better, and the current page those free trial buttons point to is /get-started/, so it seems like a better fit.

WDYT?
