Google announced a deal to buy business analytics software vendor Looker for $2.6 billion. The acquisition will extend the capabilities of Google’s existing cloud database products by letting users create shared business metrics and develop applications. Looker will continue to run on all cloud database platforms.

Klear, an influencer marketing platform, says it can fix this with a newly-announced feature to estimate campaign ROI by calculating Earned Media Value – that is, the how much it would cost to buy the same amount of coverage in paid media (a.k.a. advertising).

Lytics has launched Cloud Connect, which lets users create SQL queries to extract an audience from a cloud database and send it to an ad network.  They describe it as a “freemium” product but don’t get too excited: the free version connects just one warehouse to one ad network.
