The 37-year-old took over for Twitter co-founder Jack Dorsey, who announced his resignation on Monday.
Mr. Agrawal joined Twitter in 2011 and worked his way up to become the company’s chief technology officer.
He’s been described as a steady pair of hands, and he’s had a big job ahead of him.
However, the announcement of his hiring has sparked widespread joy in India, where the microblogging network has more than 30 million users.
Many people praised his hiring on Twitter, noting that he is now the youngest CEO of an S& P 500 business. Some have included him in the long list of Indian CEOs of multinational technology companies.
Mr. Dorsey said in a message on Twitter on Monday, “Parag has been at the helm of every crucial decision that has aided in the turnaround of this company. He’s inquisitive, perceptive, reasonable, creative, demanding, self-aware, and humble. My faith in him as our CEO runs deep.”
Mr. Agrawal tweeted shortly after the announcement that he was “excited for the future.”
“Thank you so much, Jack. I’m both honoured and humbled. And I appreciate your ongoing mentorship and friendship “He penned. ” I started working for this company ten years ago when it had fewer than 1,000 people. Despite the fact that it was a decade ago, those days seem like yesterday to me.”
Mr. Agrawal holds a PhD in computer science from Stanford University and is a graduate of the famed Indian Institute of Technology (IIT).
Prior to joining Twitter, he had several research positions at Microsoft, Yahoo, and the US telecoms major AT&T.
As Twitter’s chief technology officer, he was in charge of the business’s technological strategy, spearheading efforts to “increase development velocity while advancing the state of machine learning across the company,” according to the company.
Mr. Agrawal’s past tasks were all away from prying eyes, but with his current role, he has gone from relative obscurity to a big public figure overnight, and every move he takes now will be closely examined.
Already, a tweet he sent in 2010 with a quote from the Daily Show is being cited as evidence that he is left-wing, with many labeling him racist. Mr. Agrawal has yet to issue an official statement.
His nomination as CEO of Twitter comes at a time when the social media company and the Indian government are at odds over free speech and fake news on the platform.
