I think your landingpage looks good, but overall I have a hard time seeing exactly how it makes life easier for me.

I have worked in most of the roles you describe, but even after having scrolled to the bottom, I don't exactly understand how it is tailored to the roles.

What I was left with is that you have boards and progressbars. Doesn't really compare to the stuff I already use.

Maybe you could explain even better how each role can tailor an interface to meet their needs, and what you provide better than other software out there.
