Campfire

37Signals decided to market a combined package of its key SaaS services for business - 37signals Suite, similar to how Google sells its services as Google Apps. 37signals Suite includes Basecamp (project management system), Highrise (CRM system), Campfire (group chat, which can be used as communication tool in this bundle) and Backpack (group organizer+wiki, which can be considered as an intranet portal in this bundle). The integration between applications in the package doesn't rock for now, but at least the user base will be unified. 37signals Suite is prices so that in most cases it's cheaper to buy the whole suite than two separate services. Price starts at $99 per month - for 35Gb of memory, 35 projects in Basecamp, 20000 contacts in Highrise, 5000 pages in Backpack, 50 simultaneous chats in Campfire. Though it seems much more expensive than the cost of Google Apps (50$/year), but you shouldn't forget that Google charges this fee for each user, and in 37Signals Suite the number of users is unlimited.

Jason Fried, 37Signals co-founder, exactly knows how to create beautiful systems. Basecamp users and Ruby on Rails developers know this. Recently he published the video with his vision of how to create a beautiful workspace (on the example of 37Signals) and how online tools can help. Jason started with the fact that in most companies collaboration is organized absolutely wrong. It's based on the constant interruptions. Employee just turns on the computer, and the interruptions begin: instant messages, email notifications, phone calls and of course, co-workers that come and ask something. No one can work productively in such environment. And, often collaboration software (especially messengers and microblogs) doesn't help to mute this noise, but increase it.
