We're happy with the numbers, but I think they can be partially explained by our long beta period. People have been asking us "when can we start paying?" since the beginning of the summer.
We are entering a crowded market, but it's not as bad as you may think. A lot of the competing project management software startups take the exact same approach. So we see Basecamp and all the Basecamp clones as just a single competitor, and we deliberately take a different approach. As a result, some people will prefer their approach, and other people tell us they've been looking for something like Thymer for over ten years, and that's the kind of feedback that confirms we may have found a good niche.
