Founded in 2007, Overamstel manages a diversified portfolio of imprints including Carrera Culinair, Hollands Diep, Lebowski, Moon, and The House of Books. These brands span fiction, non-fiction, and children’s literature, supported by a strong multi-format presence in print, audiobook, and e-book. Today, the Overamstel catalogue features acclaimed authors such as Annejet van der Zijl, Carry Slee, Agatha Christie and Barack Obama.

Overamstel’s current CEO Martijn Griffioen will continue in his role following the acquisition. Helena Gustafsson, Chief Content & Publishing Officer of Storytel Group, will join the Overamstel board as Chair, while Stefan Wård, Chief Financial Officer of Storytel Group, and Laura Stoorvogel, Country Manager Netherlands at Storytel, will join as board members.

“We are immensely proud to officially join Storytel Group’s prestigious portfolio of publishing houses. After a long-standing and fruitful relationship, this transition feels like a natural evolution. I look forward to working alongside Storytel to continue pushing the boundaries of traditional publishing and to keep expanding the impact and visibility of our authors”, says Martijn Griffioen, CEO Overamstel.

As part of Storytel Group, Overamstel will retain its distinct identity and continue to develop both new and established authors as an independent publisher within the group.

“A warm welcome to the entire Overamstel team to Storytel Group. By uniting Overamstel’s rich publishing heritage with Storytel’s digital reach, a vibrant, shared home for creativity is being built. The journey ahead offers a wonderful opportunity for all talented colleagues to work together in bringing even more magic to book lovers across the Benelux region and beyond”, says Bodil Eriksson Torp, CEO Storytel Group.

In 2025, Overamstel reported sales of €17.4 million with an adjusted operating profit (EBITDA) of €1.3 million. Physical book sales accounted for approximately 75 percent of the publisher's revenues in 2025, demonstrating the company’s strong and resilient print portfolio, while growing digital sales made up roughly 25 percent.

The agreed purchase price will be paid fully in cash, financed through Storytel Group's existing liquidity. 

Overamstel joins Storytel Group’s existing portfolio of publishers, which includes Norstedts Publishing Group, Gummerus, People’s and Storyside, as well as majority stakes in Lind & Co and Bokfabriken.
