Our take
Kit, formerly ConvertiKit was founded in 2013 to help online creators and bloggers make money through email marketing. The company has amassed more than 550,000 creators that reach 590+ million fans.
Following a boost to email marketing engagement rates, Kit’s strong existing network put it in a good position to take advantage of it. Add to that the increasing shift towards eCommerce, and the company’s offering is increasingly looking like a smart solution for content creators looking to monetize.
Kit’s acquisition of musician marketing platform FanBridge sees the platform scooping up musicians looking to explore alternative revenue streams online following the pandemic throttling of tours and live gigs. With plans to add Spotify and BandsInTown integrations, as well as ‘tip jars’, this is an interesting direction to see the email marketing company expand into.
