Gauri Manglik of SpotOn, which launched yesterday at TechCrunch Disrupt, didn’t make it to the finals despite home court support from members of the New York tech scene. Enthusiasm for SpotOn was evident on Twitter, but some of it was misdirected not to the start-up’s handle @getSpotOn but to the empty @SpotOn (and once, to the competition: @sonarme). But Ms. Manglik did just meet Google’s Marissa Mayer backstage at the conference. “SpotOn is giving @marissamayer a demo backstage,” TechCrunch’s Erick Schonfeld tweeted. Ms. Mayer looks impressed! Or at least, engaged.
