Butt was one of the founding members of Paragon Publishing before it was taken over by Highbury House Communications, which publishes Health & Fitness, Fast Car, DJ and What Video & TV, in 2003. He is currently editorial director for 45 consumer and B2B magazines.
Butt has launched more than 60 magazines including DVD Review, Play and Made Easy, and, more recently, oversaw the management buy-in by venture capital group 3i and the sale of Paragon for £32m to Highbury.
Butt said: "It's been an exhilarating 13 years. Turning Paragon into a high-quality magazine publisher -- no longer a follower, but a leader -- has been a huge challenge, and I am extremely proud of the company, its products and its people."
Butt will leave the company at the end of August for a "well-needed break" and to pursue other challenges.
Highbury House Communications is now the third-largest UK publisher of consumer and B2B titles. Last year's integration with Cabal Communications and Paragon ensured a turnover of £108m, up from £93m in 2002.
