After a turbulent year during which the top editor was fired and rehired, The Markup, a website with ambitions to combine investigative and data-driven journalism to cover technology, will make its formal debut Tuesday.

“We’re calling it a launch,” said Julia Angwin, the editor in chief. “But we’re also cognizant of the fact that we’ve had several big public announcements prior to this, so this is a ‘show our work’ moment for us.”

“Show our work” is also a motto of The Markup. Alongside its articles, it will provide readers with detailed explanations of how its reporters got their stories.

The Markup was founded in 2018 by Ms. Angwin, an investigative journalist and a veteran of The Wall Street Journal and ProPublica; Jeff Larson, a data journalist who also worked at ProPublica; and Sue Gardner, a former head of the Wikimedia Foundation.
