I'm actually working on a new start-up to try to take a stab at this problem. Would love to get some beta users, if any of you are interested: http://hellofocus.com/
Could I politely recommend that you put some screenshots on your front page. Generic statements and stock photos really don't make anything more than a superficial impression.
I'd like to get an idea of what I'm signing up for before I commit.
Thanks for the recommendation. We do have some screenshots on the features page. Ideally next iteration will have more focus on the screenshots. Much of our design is changing at the moment while in beta.
It seems the data analysis is an important part of your product; I know this is probably too early, but consider building an API to enable companies to plug-in their existing solutions into yours. It would be hard for us to move away from our existing system, especially since it's integrated with our accounting, billing, and CRM.
