Cozi, an intriguing Seattle based startup that’s most easily described as a social network for a family unit, is announcing an investment and business deal with newspaper conglomerate Gannett Co. later this morning. The size of the investment is not being disclosed (we believe it is $8 million, however). Cozi has raised $7.3 million prior to this round.

Cozi lets family members keep a group journal, share photos, organize chores, share calendars and create todo lists. There’s a significant overlap with genealogy sites like Geni, as well as some of the life story sites we’ve profiled from time to time. But I haven’t seen anything quite like Cozi, which also has mobile and Outlook syncing to keep everyone on the same page. The demo here gives more feature details.

The service now has 600,000 registerd family members and says it’s adding 2,000 new ones per day.

Cozi says they’ll be delivering Gannett content, particularly local content (likely via Topix and other properties). It’s also clear Gannett will be pushing this to its users – they claim to reach 75% of all U.S. adults through its various sites.
