Berlin has gained international attention, and financing, as an incubator for technology start-ups in recent years. But there are no comparable high-profile female figures like those emerging in Silicon Valley in California: Sheryl Sandberg, the chief operating officer at Facebook, or Marissa Mayer, the chief executive at Yahoo, for example.

“There are quite a lot of women out there who are just doing it,” said Verena Delius, chief executive of Goodbeans, which creates apps for children. “But we have to get organized. You need to have good role models who are very transparent about how they are doing it.”

There are several women in Berlin involved in interesting start-ups and technology projects or who founded their own companies. But none has achieved the widespread recognition of their male counterparts, said Jess Erickson, 28, who arrived in Berlin from New York in 2010.

Ms. Erickson cites Zoe Adamovicz as an example. At 33, Ms. Adamovicz, a native of Poland who came to the city to study at Humboldt University of Berlin, is chief executive of Xylogic. The company recently introduced a product to help smartphone users navigate the jungle of apps and is the newest of six that she has founded since 1999.

“Here’s a woman who’s sold many companies, built many companies, but she just doesn’t have that much media presence,” Ms. Erickson said of Ms. Adamovicz, a founding member of the Geekettes. “I thought, ‘Wouldn’t it be cool to showcase these women and share their stories and inspire more young women to pursue their own dreams of founding their own company?”’
