And that the first month of TechStars is a lot of back-and-forth, matching startups with mentors and mentors with startups. Where all three months of YC is build, build, build. (And getting ready to demo.) To stretch an academic metaphor, TechStars reminds me of a residential college (where you do everything with your cohort) and YC reminds me of the traditional Oxbridge model (some lectures, lots of independent study and regular one-on-one sessions).

Neither is particularly "right" or "wrong", they're just different models.
