With fresh capital in its coffers, Dropbox appears to be on somewhat of an acquisition spree, albeit a quiet one. Following the cloud storage company’s recent purchase of workplace chat solution Zulip, it’s in talks to acqui-hire Berlin-based Readmill, the social and shareable reading platform. According to what we’re hearing, the deal value is around $8 million, made up of mostly stock but with a small amount of upfront cash for the startup’s founders who will be moving to Dropbox in San Francisco.
