Cruise booking platform Dreamlines has raised €45 million in Series E funding. The investment was led by Princeville Global, with participation from existing investors including Holtzbrinck Ventures, Target Global, Dimaventures, Hasso Plattner Ventures, TruVenturo and Global Founders.

Based in Hamburg, Dreamlines offers the largest portfolio of cruises around the world. The travel tech startup has expanded into 10 countries since launching in 2012, and partnered with over 100 cruise operators.

“As an early investor, HV Holtzbrinck Ventures has seen Dreamlines grow by a factor ten since its initial investment into the European market leader,” said Christian Saller, General Partner at HV Holtzbrinck Ventures and chairman of the board at Dreamlines. “The new investment will allow Dreamlines to continue this success story.”

The investment will be used to further the startup’s growth and international expansion.

“Our strong growth and European market leadership are an ideal base for further expansion,” said Felix Schneider, Dreamlines CEO and founder. “We’re excited to have Princeville Global as a new, experienced, and competent partner at our side to accomplish our vision.”

“The cruise industry is the last sizable, global travel segment to be disrupted by a tech-focused online booking platform,” added Emmanuel DeSousa, Managing Partner of Princeville Global. “Under the leadership of its visionary founders, Dreamlines is uniquely positioned to continue transforming the cruise industry to an online model, leading in Europe and expanding around the world.”
