Wattvision is a ycombinator-funded startup. At the end of the YC program, startups demo their work to a large set of investors across two YC Demo Days. We presented to the first set of investors yesterday, and we're presenting again today! Wish us luck!
We just set up our twitter account! Follow us at http://twitter.com/wattvision
Wattvision answers the question: what's my current energy use? And how does it compare to my friends' usage? ;)
