 😍About Us
 
 
 
 
 
 
 
 ⭐️ Where Celebration Meets Technology: &Ccedil;i&ccedil;eksepeti
 
 
 
 Celebrations are life&rsquo;s most special and heartfelt moments. Since 2006, we have been on a mission to combine the joy of gifting with the power of technology. Every flower delivered, every gift shared, carries our signature.
 
 
 
 Our purpose
 
 is to transform the flower and gift experience&mdash;from production to delivery&mdash;while positioning T&uuml;rkiye as a global hub in this industry.
 
 
 
 
 
 
 🚀 From Using Tech to Shaping Its Future
 
 
 
 We go beyond simply taking orders. From our software infrastructure to logistics optimization, every stage is driven by data. By developing our own products and integrating technology into every step, we continuously elevate the customer experience.
 
 
 
 
 
 
 🇹🇷 100% Local Capital, Global Vision
 
 
 
 Between 2011 and 2021, our partnerships with Amazon and Hummingbird Ventures fueled rapid growth. In 2021, we became fully Turkish-owned&mdash;an independent brand driven by our belief in T&uuml;rkiye&rsquo;s potential.
 
 
 
 
 
 
 🌍 From T&uuml;rkiye to the World
 
 
 
 Our production journey began in 2019 with lilies and has grown to include orchids, chrysanthemums, roses, and sunflowers. Next is our state-of-the-art rose greenhouse in K&uuml;tahya, set to become Europe&rsquo;s largest enclosed facility.
 
 
 
 
 
 
 🤝🏻 We Produce Together, We Grow Together
 
 
 
 Together We Go Beyond is more than a motto for us &mdash; it&rsquo;s how we work, grow, and succeed. We push boundaries through teamwork, curiosity, speed, and data-driven decision-making. We believe in learning together, achieving together, and celebrating together.
 
 
 If you&rsquo;re ready to be part of a fast-growing, award-winning, and impactful company, join us and help shape the future of celebration.
