But the President, his supporters, and Republicans in Congress have repeatedly criticised the company and its social media competitors for what they have called bias against conservatives, something Twitter denies.
"Lots of subjects discussed regarding their platform, and the world of social media in general".
Trump tweeted that he had a "great meeting" with Dorsey and that he wants to keep an "open dialogue" with the tech executive.
The president complained that his follower count would be "much higher" if Twitter "wasn't playing their political games".
It's the last quarter Twitter says it will break out monthly-active-users (MAUs), a metric that has always been a standard for social-media analysts.
Twitter said during the call it's also deployed new machine-learning models to find abusive tweets before they are reported.
For the first quarter of 2019, Twitter's revenue rose 18% from a year ago to $787m, surpassing Wall Street expectations of $776.1 million. "We are constantly working to improve our systems and will continue to be transparent in our efforts", a Twitter representative said.
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".
"We are reducing the burden on victims and, where possible, taking action before abuse is reported".
The president quoted Fox Business Network anchor Maria Bartiromo, who said that the "best thing ever to happen to Twitter is Donald Trump", before launching his attack.
"He wrote on Twitter that the company "[did not] treat me well as a Republican ... very discriminatory". "Very discriminatory", he said, and called for "more, and fairer, companies", in an apparent reference to USA lawmakers' interest in regulating tech companies. Apparently, and unsurprisingly, a "significant portion of the meeting focused on Trump's concerns that Twitter quietly, and deliberately, has limited or removed some of his followers".
Carlos Monje, Twitter's public policy director, said at a Senate hearing earlier this month the site "does not use political viewpoints, perspectives or party affiliation to make any decisions, whether related to automatically ranking content on our service or how we develop or enforce our rules".
