Cloud is important for Google because growth is slowing in its core search advertising business. Google already has analytics tools, but the company noticed many of its customers were also using Looker, Kurian said in an interview.
"Looker complemented the Google Cloud analytics foundation," he said. Google doesn't plan to cut off Looker from working with its competitors, because many of its customers use more than one cloud, Kurian said. Working with other cloud systems is a critical part of Google's overall strategy, he said.
Kurian has been concentrating on hiring new sales people and refocusing Google's cloud efforts on several key industries. Investors and analysts have repeatedly asked when the company will do a major acquisition to boost its presence in the space.
"Many people have asked us for many months, 'Are you rushing to do acquisitions?"' Kurian said. "We've been very disciplined in building our sales, go-to-market capability, and our own products. We've chosen Looker as a very complimentary technology that a lot of customers will find value in very quickly."
The two companies already share more than 350 joint customers, including BuzzFeed, Hearst, King, Sunrun, WPP Essence and Yahoo!. The acquisition of Looker is expected to be completed later this year, subject to regulatory approval.
Charlotte Slaiman, policy counsel for consumer advocacy group Public Knowledge, said Google probably realises it's under the microscope on any M&A deals, but the Looker purchase seems to be a "vertical merger," which are harder for antitrust authorities to block. "But there still might be real concerns," she said.
Looker's Chief Executive Officer Frank Bien will stay on at Google and report to Kurian. Bien has a long history building successful cloud startups and has sold some of them to companies including VMware Inc. and EMC Corp. Lloyd Tabb, who co-founded Looker in 2012, was an early Netscape executive and went on to help shape Mozilla.
Looker's investors include Kleiner Perkins Caufield & Byers, Meritech Capital Partners, Premji Invest, Redpoint Ventures and Goldman Sachs Group. The company was valued at US$1.6b after a venture capital investment late last year, according to data firm Pitchbook.
