Techstars is incredibly transparent with their stats. Full funding data available here: http://www.techstars.com/companies/stats/
I just pulled some numbers quickly...
In the last 3 Techstars NYC batches (not including the most recent), there were 37 companies with median funding of just over $1.6 million. 28 are still active, 6 have been acquired and 3 have failed.
