Exec, a mobile app that instantly gets people to do your errands, has raised $3.3 million, according to an SEC filing. The company's co-founder Justin Kan, who is also behind Justin.tv, Twitch.tv and SocialCam, says he's not ready to disclose investors yet, except to say that there are around 25 different individuals in the round. The filing only shows Exec's team on it, so it's hard to tell who the firms or angels in the round are. What's Exec? It's kind of comparable to TaskRabbit, because you can call on people to run your errands from an app. But Exec doesn't require a bidding process and it calls up 'Execs,' or people to do your tasks, instantaneously. It also has a flat rate of $25 an hour. Exec covers all sorts of errands -- deliveries, chores, cleaning, even art. One 'Exec,' who cleaned my house once, has also coached YC founders on their pitches for Demo Day. Seriously."This money is for building out the San Francisco Bay Area market," Kan said. read more..
