The full Stanford course materials for the Jan-Mar timeframe are at stanford.coursera.org/cme184-001. The startup.stanford.edu URL tracked the first few weeks, but this was redundant for Stanford students and another page to keep up to date. So the material there is more of a teaser for people interested in the Coursera MOOC class.

That said, it will be more useful for the Coursera students to have a site that is accessible when logged out, so look for startup.stanford.edu to track the MOOC course material beginning tomorrow evening or so.
