One problem I've seen in start ups as they scale isn't the lack of good documentation but the lack of information organization and hierarchy. The cost you pay is repeating experiments/trials, and generally slower development. The best way, I've found to overcome this, is to just talk to people and construct an information map/hierarchy as a mental model. Obviously, this process can't scale with the business. I wonder if this tool would be useful for software/product dev in start up environments?
