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. Revenues were boosted by ad sales that also rose 18%, to $679m.
Twitter chief financial officer Ned Segal said: "We're delivering strong results with ad revenue up 18 per cent year-over-year, demonstrating Twitter's unique value proposition for advertisers as the best place to launch something new or connect with what's happening". "Very discriminatory", he said, and called for "more, and fairer, companies", in an apparent reference to USA lawmakers' interest in regulating tech companies.
But Twitter no longer will use that measure, switching instead to "monetizable" daily active users - 134 million in the past quarter, up from 120 million previous year.
Still, Twitter is ending reporting of that metric "on a high note", with monthly active users rising quarter over quarter for the first time since at least early 2018, noted Jasmine Enberg, an analyst at EMarketer. Big complaints from many people.
"No wonder Congress wants to get involved - and they should", he wrote.
Any reduction is likely the result of Twitter's recent moves to remove millions of suspicious accounts after it and other social media services were used in misinformation campaigns attempting to influence voters in the 2016 USA presidential race and other elections, Reuters reported in October.
Trump had tweeted earlier Tuesday that Twitter didn't treat him well and that he would have more followers "if Twitter wasn't playing their political games".
The meeting comes as Trump continues to attack the tech industry, threatening to regulate Facebook, Google and Twitter out of concern that they censor conservatives online - allegations that those companies deny.
The company posted profit of $190.8 million, or 25 cents per share, for the first quarter.
The earnings report also included details of an experimental app that the company has been developing to make the social media site more "conversational".
