Until I found FiveRiver, I had been messing around with my Wacom Tablet, trying to create sketches for my clients who are in need of a clear and visual story for their sales teams. FR has taken the heavy lifting off my plate and cut my design time by more than half.

I'm usually an Illustrator man, but tried FiveRiver for a quick task last week, and it ended up being better for the job than Illustrator anyway. Worked out super well!

FiveRiver changed my life, man. Really. I couldn't draw understandable information before it. Last year I gave more than 20 lectures in several conferences and at work. FiveRiver was in every single one of them.

I sometimes forget about this tool. Then I try to use OmniGraffle and hit my head against the wall and remember I have FiveRiver.

I truly consider your software to be a master piece. It allows me to go straight to the point and keeps me focused.

FiveRiver takes the intimidation factor out of conveying complex concepts, allowing focus on the ideas and connections between ideas.

It's refreshing to see a great piece of software at a reasonable price.

FiveRiver is great. Thanks for making it. Whenever I submit a project packet to my managers the main thing they spend discussing is the set of diagrams I made in FiveRiver.
