CHRGR, with a valuation of $4 million, is raising funds on SeedInvest. The company is the manufacturer of on-the-go, in-hand phone chargers and manufactures pre-charged batteries that allow users to charge their mobile phones anywhere, at any time, without tethering to an outlet. At the same time, the batteries become an opportunity for advertisers to put their brand names in the hands of the customers. CHRGR has reported repeat successes with clients like Red Bull, Instagram, Nike, and Audi, and three-times revenue growth year-over-year since 2016. John Mullin and Lucas Hearl founded CHRGR in May 2016. The current crowdfunding campaign has a minimum target of $100,000 and a maximum target of $600,000. The campaign proceeds will be used for growth and expansion.
