Small agency. Serious software.
A premium digital agency in Athens, built on sixteen years of shipped projects and a deliberate refusal to grow into an agency. Senior engineers write the code; designers stay close to the work.
TWENTYONE WEST COAST TRVL STORIES PC (G.E.MI. No: 191601903000): on paper, we sound like a Dr. Dre record label. In reality, we're busy writing custom code until the sun goes down.
Founded by Panagiotis Athanasakopoulos, TWENTYONE is a premium digital agency built on 16 years of successful projects and deep digital expertise. We're small on purpose. Senior engineers write the code, designers stay close to the work, and we completely eliminate the "junior army" and the agency middle layers between the people who think and the people who ship.
We like the hard projects — the complex integrations, the ten-year data models, and the rescue migrations that others give up on. While we build deceptively simple user experiences, most of our work is invisible: robust APIs that don't fall over during peak season, and software that runs flawlessly at 4:00 AM when someone depends on it.
With a specialized focus on the hospitality industry and an extensive customer base of hoteliers, we build tailored digital solutions that blend usability, robustness and scalability to make business operations effortless.
