About

Joe Pettersson (he/him) lives in London with his partner and their cat Zelda. He hates writing about himself in the third person. He's a dual Swedish/British citizen, which means on one-side he loves ice hockey and has an uncanny ability with flat-pack furniture, and on the other, he never performs adequately at international football tournaments.

Joe has been working with technology for more than twenty years, a lot with the web (building stuff for it and building the stuff that powers it) as well as machine learning and distributed systems.

Joe works at Banked (❤️) where he's the CTO President, and his role spans technology, product, commercial, finance and IR. He's had senior engineering leadership roles at Permutive, QuantumBlack, Microsoft and Skype as well as being an Associate Partner at McKinsey & Company. He has a few patents, has spoken at quite a few conferences and has been known to write (for which he remains profoundly apologetic).

Joe's professionally passionate about open source software, building inclusive teams and being an advocate for Wheaton's Law. He's personally passionate about Arsenal Football Club, the art of Caravaggio (chiaroscuro is "his jam") and the 1995 movie Hackers.

Outside the day-job, Joe: invests in start-ups and co-founded an organisation that helps young offenders and gang members change their lives.

“j11n” is a contraction of Joe’s first and last names (in the style of Andreessen Horowitz’s a16z). He saw the opportunity to use a four-letter .com domain and grabbed it with both hands.
