en.wikipedia.org/wiki/John_Collison

Forbes’ contemporaneous coverage of Stripe’s 2016 funding round says John Collison specifically "is now the world's youngest self-made billionaire" at age 26. The same article separately says Patrick Collison, 28, was "the only other self-made billionaire[] in the world under age 30" (along with Bobby Murphy). A second Forbes ranking that year repeats the distinction: "That makes 26-year-old John Collison ... the world's youngest self-made billionaire" while Patrick, at 28, is listed separately as another under-30 self-made billionaire.

So the article’s wording that "the Collison brothers became the world's youngest self-made billionaires" is inaccurate because it assigns the "youngest" superlative to both brothers. The reliable sources only apply that title to John, not Patrick.

The claim gets the podcast’s name wrong. Apple Podcasts lists the show title as "Cheeky Pint" and describes it as a Stripe podcast hosted by John Collison. Stripe’s own site also refers to it as "Cheeky Pint" in multiple places, including a job listing and a customer story page.

Because the official publisher and distribution page both use "Cheeky Pint" with no leading "A," the quoted title "A Cheeky Pint" is incorrect.
