Starting in product management and development, over the years he rose the ranks, eventually becoming Oracle President of Product Development in January 2015.
Around that time, Reuters reported that perhaps more than anyone at Oracle at the time — including co-CEOs Safra Catz and Mark Hurd — Kurian had the ear of founder and CTO Larry Ellison. According to the Reuters report, Ellison turned to Kurian for advice and affirmation on product decisions.
“He always looks back at Thomas and says, ‘Thomas what do you think? Thomas let’s do that.’ It was something to watch them,” a former Oracle executive told Reutors.
As president of product, Kurian oversaw Oracle's cloud computing efforts, but conflict between Ellison and him began to emerge. Kurian's demeanor is reportedly similar to that of Ellison —outspoken and opinionated.
On September 5 of this year, Kurian announced he would be taking some time off from Oracle, but the company said that he was "expected" back. On September 28, however, Oracle announced Kurian's resignation.
According to his LinkedIn at the time of his departure, around 35,000 people in 32 countries, or about one-quarter of the company, were reporting into Kurian.
Kurian was replaced by a longtime Microsoft engineer exec named T.K. Anand, who had joined Oracle only months earlier.
On November 16, 2018, Google announced that Kurian will be named the new CEO of Google Cloud, replacing its current chief exec, Diane Greene.
Kurian will join the company on November 26, and will assume the leadership role in January.
