Rock Weekly: Deconstructing the Castlight IPO

Rock Weekly


February 17, 2014

Last week we learned some interesting numbers: An estimated 17M wearable bands will ship this year, Jawbone has a $3B valuation, and Castlight booked $13M in revenue in 2013.  We also went ahead and read every word of Castlight’s S-1 filing so you could kick back and enjoy the tl;dr version.

Today we’re proud to announce Rock Health’s latest investment, Ambient Clinical Analytics. Ambient is enabling better real-time decision-making in the ICU and emergency rooms.
