The Cambridge Satchel Company, one of the UK's best known small British business success stories, has taken another step into the retailer big league after snapping up a new chief marketing officer from Net-a-Porter.

The group confirmed in a statement that Mario Muttenthaler has been appointed as chief marketing officer at The Cambridge Satchel Company, after moving from online fashion retailer, as sales and marketing director.

Previous to that role he was Net-A-Porter's marketing manager.

"I am delighted Mario has joined us. He brings a wealth of experience in digital brand development and e-commerce," said Julie Deane, founder of The Cambridge Satchel Company.

"As we expand into new markets and build our global digital presence this is the very reason I chose to partner with Index. We can now attract a world class team who will grow the business and boost the profile of The Cambridge Satchel Company as an internationally-recognised online brand."

In January this year, The Cambridge Satchel Company sealed its position as one of the most exciting entrepreneur projects in Britain after it won $21m (£12.4m, €15.4m) in funding from Index Ventures.

Starting off as a homemade venture in mother-of-two Deane's kitchen with the help of her mother Freda Thomas and a modest £600 budget, the leather goods brand and maker of satchels became a "Made in Britain" worldwide phenomenon.

From featuring on influential fashion blogs to being chosen as gifts for the cast members of the hit US TV show Mad Men as a wrap party gift, the satchel maker has become a celebrity must-have.
