Seattle-based Cozi offers a range of tools for households, like calendars, to-do lists, photo organizing and blogs. It had previously raised at least $8.3 million. With the investment, Gannett will get a seat on the Cozi board. As for the strategy here, Gannett plans to push the Cozi brand across its various web and print properties. Cozi gets deeper access to Gannett’s local content, opening up new opportunities. Though the announcement doesn’t say so specifically, it looks like Cozi should be a good fit with Gannett’s mom-focused properties (like this one). Cozi was launched in 2006 by ex-Microsoft (NSDQ: MSFT) execs and claims 600,000 users. Release.
