Here's something we didn't share in the blog post. It's some of the print outs we brought along with us to the interview. No reason not to share it I guess. It shows some graphs illustrating virality, connection clusters (just one of them) and revenue growth. http://www.yogatrail.com/yogatrail-stats.pdf

Hey, just a quick piece of feedback on this. You define virality as "the percentage of users invited by other users". That's a very non-standard definition.

Usually virality is measured as "the average number of new users invited by any given user". I'd strongly suggest using that as your definition.

In that case, we're hitting it out of the park - over 4 invites sent per user, but these invites convert at ~25%. There's also "k factor" (invites sent x conversion rate), and the interval between user #1 bringing on user #2 is also important... guess there are many ways to present virality :)

That kind of info (4 invites on average per user, 25% conversion rate) is THE critical information. If you want to talk about virality at all, the fact it's not in your presentation is a serious defect you should correct.
