Studio Posti is the creative studio of Finnish-born illustrator Pietari Posti. After studying graphic design in Lahti, Finland, Pietari moved to Barcelona where he founded the studio — and has since relocated to A Coruña, on the Atlantic coast of Spain, where he continues to work with a wide range of international clients across advertising, publishing, and editorial.

His bold shapes, expressive style, and deep sense of craft have attracted clients including Apple, Nespresso, Random House, Starbucks, Monocle, The New York Times, The Guardian, Wired, The Washington Post, Runner's World, and Iittala. Pietari received the Victoria & Albert Museum Best Book Cover Illustration award for his work on Arthur Ransome's Swallows & Amazons series.

His background in graphic design informs every composition — small editorial pieces arranged with a designer's eye, and typography playing a central role in the posters, book covers, and identities he is commissioned to create. Infused with a deep sense of tradition and a modern aesthetic, his work exudes both heritage and timelessness.

Pietari is known for being a warm and collaborative presence throughout the creative process — clients tend to find him as easy to work with as the results are rewarding.

Studio Posti's work has been featured in numerous illustration and design publications worldwide.
