Nothing. They are the most unethical, money minded company out there.

Nifty has a great interface and workflow that's beyond its years. Not only does it put all the information you'd need to get from start to finish in a project, you can have your whole team working on projects and get a high-level overview of things easily. Where some PM tools leave things out, Nifty does the most needed ones, and does it well. You've got a Gantt chart for tracking progress, you can switch to a Kanban style for agile/scrum projects, or have simple to-dos to help stay abreast of smaller tasks/projects. Nifty is exactly as the name suggests, and then some!

NIFTY managed to bring the best of product/project management into a very simple-to-use UX. I like their approach to the swimlane view, if you don't know what that is, then you'd better check it out ;)
