Quick feedback on the holding page.
On my laptop, above the fold I see all the way to your optin box and there is no indication that there is anything below. Some indication that I should continue to scroll would be helpful, even if it’s just an arrow of some sort, or a “not convinced? keep reading”.
It’s fairly unconventional to ask for a last name for an email list. First name / email should be enough, and just email is better. That should give you a healthy boost in your conversion rate (split test it to find out!)
I love the watercolor look with the swinging images. It does make me scroll more on my small (12") screen, but that didn’t bother me.
After reading through it all, I’d still like more info. I’m sure that will come as you progress, but “productivity tools that speak to each other” is still too vague. What benefit do I get from them all being connected? What will I be able to do that I can’t do now? What tools will you be replacing? How will you save me time and money?
