On the topic of Web 2.0 startups and their relevance to the enterprise market, Matthew McCall from Portage Ventures, notes in his blog that we have yet to see a lot of startups pushing new-fangled web applications based on Web 2.0 technologies. Nearly all the buzz is around B2C services because that's what investors and the press are excited about at the moment, thanks in no small measure to Google and high-profile sites like Flickr, etc. Enterprise Web 2.0 buzz is evolving rather differently from the earlier Web Services craze, where new vendors did start selling (with difficulty) directly into the enterprise IT department.
It will indeed get a lot more interesting once there are real Web 2.0 applications for the enterprise that threaten established software vendors. And I wouldn't be surprised if some of the (few) surviving Web Services startups from the early noughties rebrand themselves as Web 2.0 tools or platform vendors. Ultimately, both traditional infrastructure (middleware, app servers) and application vendors will be affected. Enteprise-grade development tools are already available from Backbase, and a web front-end integration platform from Kapow Technologies. Anyone know of others?
