LA-based startup Melon, formerly Axio, also set a $100,000 crowdfunding goal for its headband EEG tracker -- and ended up with $290,000 by the end of the campaign. Melon relies on a partnership with another company, Neurosky, to develop the EEG sensors. Melon has three sensors compared to Emotiv's five. Its campaign also focused more than Emotiv's did on its mobile app, which includes learning algorithms to help the user deduce how different environmental factors affect their mental state. Notably, Melon's device was available to Kickstarter backers for just $100, half as much as Emotiv's initial price point.
