Well, since our beta a few months back, we have had about 180 companies sign up, but all are under the 10 employee limit, which at the moment is free, so we haven't actually had anyone pay for a higher tier as yet.

Of that 180 sign ups, about 30 or 40 are quite active and visit the site often, although it is hard to judge because some only need to revisit the site once a month or so to update details and respond to reminders etc.

We are looking at scrapping the free 10 employee limit soon, and making everyone pay (except the early sign ups - we will honour their free tier pricing indefinitely).
