> The core product - providing a third-party system that handles the mechanics of paging people during a production issue - is something that virtually all software companies could use, in theory. I think "virtually" is a bit strong. There are still a lot of software companies that build software that doesn't rely on company-controlled production systems. Also, in practice companies that have large-scale production systems tend to have dedicated 24-hour human monitoring. Thus, I do think PD is hitting a niche within a niche: small-medium sized companies that rely on always-up servers.
