I like the idea of the product (haven't played with it yet though) and the pitch. Paraphrasing here, since I only watched the first half of presentation earlier: "companies spend a lot of money on people and their knowledge, but people leave and take it with them"/"a lot of answers are shared in a company but they're kept all over the place in email/IMs/etc" - again, really paraphrasing, but I think that pitch of keeping the knowledge you pay for inside of the company, in a central location, will push a lot of businesses to try it. There are many products like this (basically any wiki software), but it's quite cumbersome for someone to go in and manually create/edit wiki pages. Every company I've worked with that uses a wiki usually has 1 person that has to go in to format and edit pages, because no one else will (or knows how to). Someone gets paid just to make and clean up the documentation. I think Opzi makes it simple for anyone to do that by just asking a question. I can't count how many times I've had to ask someone for info which they had in an email somewhere, and they'd have to dig around for it and forward it to me. Now they could just paste it into the answer section of the question I wrote, and when the next guy needs the same info it's all in one place. This software actually solves a real problem in both big and small businesses.
