For their Factory Girl breakfast restaurants in Berlin and Amsterdam, Erhan O. Seven and Sofia D. Sözen rely on digital technologies. They believe the future of hospitality lies in processes that are as automated as possible.
“The only way to master today’s uncertainty is to use as much tech as we can,” says Erhan.
Sofia adds, “You have to keep evolving, update every single day.”
Four years ago, Factory Girl became Berlin’s first restaurant to go fully cash-free. The change shaved precious seconds off each payment and simplified end-of-day reconciliation. In peak hours, Erhan explains, saving ten to fifteen seconds per transaction can be a game changer.

Factory Girl introduced digital menus early on. Each dish comes with a photo, so guests already know what they want when the server arrives. That shortens waiting times and speeds up service. “People expect tools that are simple,” Erhan notes. Sofia agrees, “No one wants to scroll through long menu descriptions. The most intuitive access wins.”
With luca Pay, the process is even smoother. Guests handle the bill themselves, tap to tip, get up, and leave—no waiting, no hassle.
Since rolling out luca Pay, the team has seen a clear uptick in tips. “Having tipping built right into the luca app really helps our staff,” Erhan says. “And that’s good for everyone.”
Sofia and Erhan also focus on social impact. They donate one percent of profits to companies developing climate-friendly technology. Slightly chipped plates aren’t thrown away; students can take them home for a small donation. “The feedback from young people is overwhelming,” Sofia smiles. “That makes me happy.”
Factory Girl is all about globally inspired breakfast, vibrant interiors, and a relaxed vibe—perfect for early birds, brunch lovers, and remote workers looking for a tech-savvy spot.
