I have wanted to use Mixpanel for a while. But your product is very very expensive for a Startup. When we're trying to be frugal, there's no way we can justify spending $150 per month on collecting data on just 5,000 users (where 98% of them will be free-users). Your product becomes interesting to a Startup only if they won't have to worry about paying for analytics till they're really successful. That means many millions of data-points. Not 25,000 or even 500,000.
The only Startups that can afford your service at this point are the ones that have only paying users.
