Specifically on the exit stats GrabCAD (Boston TS company from 2012) was acquired for 100 million -

And the real answer to this is that getting large exits takes a long time. Unless I'm mistaken YC, which is older than Techstars and has 50% more portfolio companies, has 3 exits over 100 million, OMGPOP, Heroku and Twitch. Granted the last one was a big one.

YC also has 4 companies with public valuations over 1 billion: Machine Zone, Stripe, Airbnb and Dropbox

Techstars should see some other big exits over time with SendGrid (couldn't find actual current valuation) and DigitalOcean ($153M Valuation in 3 years) to name a few

Also Localytics (TS Boston 2009) is well positioned for a big exit or IPO: http://www.crunchbase.com/organization/localytics
