Millarworld's graphic novels "Kick-Ass", "Wanted" and "Kingsman" have already been turned into movies by major studios. Terms of the transaction weren't disclosed.
Scottish writer Mark Millar is a former employee of Marvel and he and wife Lucy run Millarworld.
With news breaking that Neflix has purchased Millarworld, comic book fans have a lot of new digital content to look forward to.
It is the first acquisition by Netflix, the 20-year-old streaming-video pioneer that is building a library of original series and films in a bid to hook new customers around the world.
"When you have an opportunity to buy Millar, you do it".
The acquisition of Millarworld is likely financially immaterial to Netflix, Raymond James analyst Justin Patterson said.
Millar, 47, who now lives in Glasgow, said that the acquisition was "only the third time in history a comic-book company purchase on this scale has ever happened" - citing Warner Bros's buyout of DC Comics in 1968 and Disney's acquisition of Marvel in 2009. "Netflix would love to discover the next Quentin Tarantino, for example".
Netflix said in a statement the deal was part of the company's effort "to work directly with prolific and skilled creators and to acquire intellectual property and ownership of stories featuring compelling characters and timeless, interwoven fictional worlds".
Mr Millar spent eight years at Marvel, where he developed comic books and story lines that resulted in movies such as "Logan" and "Captain America: Civil War".
"Comics have been my passion my entire life".
"We can't wait to harness the creative power of Millarworld to Netflix and start a new era in global storytelling".
Since Millarworld was started, the company and its co-creators have created eighteen published character worlds, of which three, Wanted, Kick-Ass and Kingsman, have yielded theatrical films that together have grossed almost $1 billion (£768 million) in global box office. I know, I know. Some of the Marvel shows can be seen on Netflix.
"This feels like joining the Justice League", he added, in a nod to the team of DC superheroes, including Batman, Superman and Wonder Woman.
Millar was equally mum on which of his comics will become Netflix originals.
Netflix last month reported second-quarter revenue of $2.79 billion and net income of $65.6 million.
Shares of Netflix rose 0.6 percent to $181.37 on Nasdaq.
