Hägg is a Swedish-born creative director and founder working across fashion, visual culture, and contemporary image-making. His work centers on image authorship: building concepts, campaigns, and visual worlds with enough precision that they hold as more than content.

He is the founder of Intelligence Matters, an authorship-led image studio working across direction, production, and contemporary image-making.

Before Intelligence Matters, Jacob co-founded Brashy Studios with Axel Hägg in 2011. Built across Stockholm, New York, and Los Angeles, Brashy Studios became a distinct cultural world rather than only a label, developing a visual language and record that moved organically through fashion, retail, press, and celebrity. The work entered the MoMA archive because it held as more than product.

His record includes MoMA, Colette, KITH, I.T Hong Kong, Vogue, New York Times, i-D, T Magazine, Highsnobiety, Hypebae, and LOVE. His work has also been worn by Rihanna, Billie Eilish, Bella Hadid, Charli XCX, Kendall Jenner, and Kaia Gerber.
