"Lots of subjects discussed regarding their platform, and the world of social media in general", Trump tweeted.
The "great meeting" with Dorsey came hours after Trump, who has repeatedly accused Twitter - and other social media giants - of bias against conservatives, went on another scathing tirade against his favorite communication medium.
That's Trump's social media director and former golf caddie Dan Scavino glowering to Dorsey's right.
As for Trump, earlier in the day he tweeted that he was losing followers because of alleged Twitter shenanigans, writing: "If Twitter wasn't playing their political games".
Analysts were encouraged by signs Twitter had turned a corner in terms of monthly user growth and better appealing to advertisers but said that the new user metric could make comparisons between Twitter and social media rivals more hard.

After the White House meeting, a Twitter spokesperson said, "Jack had a constructive meeting with the President of the United States today at the president's invitation".
In a statement, Twitter said the meeting was initiated by the president and focused on "protecting the health of the public conversation ahead of the 2020 us elections and efforts underway to respond to the opioid crisis". Twitter is here to serve the entire public conversation, and we intend to make it healthier and more civil.

"Things are happening, names are taken off, people aren't getting through", Trump said at the time.
"No wonder Congress wants to get involved - and they should", he wrote on Twitter.
Twitter now has more than 4,100 employees, an increase of 18 percent from a year ago, and the company said it plans to keep hiring throughout 2019.
And, according to Reuters, the commander-in-chief was more concerned with the rate at which he was haemorrhaging Twitter followers.
