    TOBS sells premium organic beauty and cosmetic products via a Shopify Webstore and a retail store in Munich. We approached Dual Citizen because we were looking for a Shopify Expert with development expertise. After inspecting our existing online store, Deniz Demirsoy made us clear that we had a couple of conversion issues and recommended to switch to another theme. The migration went very fast and smooth. We were excited to see the positive results within a very short time frame. Within two months our conversion increased 50% and we could reduce our ad spending. TOBS vertreibt hochwertige organische Kosmetikprodukte über einen Shopify Webshop und einen Laden in München. Auf Dual Citizen sind wir nach einer Recherche über Shopify Expert Partner mit Entwicklungsknowhow gestossen. Nach eine Beurteilung unseres Webshops machte Deniz Demirsoy uns auf einige Schwachstellen im Hinblick auf die Konversion aufmerksam und empfahl den Umstieg auf ein neues Theme. Der Umstieg verlief glatt und die Ergebnisse waren sehr schnell sichtbar: Innerhalb von zwei Monaten stieg die Konversionsrate um 50% und wir konnten die Ausgaben für Onlinewerbung signifikant reduzieren.

    Beware of the so called ' Shopify Experts"...I was super lucky after 3 years using Shopify to find the real thing. Dual Citizen run by Deniz Demirsoy is the best thing that happened to us . Deniz is super professional, reliable and knows Shopify like an real expert should be. Please go and check his website and read his resume. You know you are in good hands. I have worked in the past with so many called " Shopify experts" and realized working with Deniz that they didn't know the app as detailed and as well as Deniz did. He helped me rebuilt both of my websites for North America and Europe flawlessly. Showed me how easy is to navigate and use Shopify, rebuilt my original website from scratch. He is super knowledgable, humble, and easy going to work with. He uses easy language to communicate with clients in case you are not a tech person. He was a pleasure to work with. The whole project process was done on schedule, flawless, and efficiently even though we had time difference - USA vs Germany. I didn't care he was across the pond. I just wanted a real Shopify Expert. I am extremely happy to have found Deniz and I highly recommend him. I will use his services again and again. Dina M Sip Nintaanzi Inc President & Co - Founder.

  • MANDALATheme customizationMar 19, 2017

    Mandala specializes on sustainable and high-quality yoga fashion. We sell our products through retail partners, our web shop and an own retail store in Munich. Deniz Demirsoy, Dual Citizen, migrated our existing 5 years old online-shop to Shopify. He streamlined our internal processes, reduced our dependency from external contractors and agencies. We got rid of an expensive inventory management system, integrated our retail and online store through Shopify’s POS module. Within the first year upon switching to Shopify we reduced our costs for technology and operations significantly. Dual Citizen helped to increase our online revenue 50%. Although we were amazed about it’s functionality and ease of administration, initially we were skeptical about using Shopify because it’s a Canadian product. Dual Citizen helped us to become compliant with EU regulations, integrated the web shop with our German fulfillment, accounting partners and processes. Beside setting up the web shop, Dual Citizen also completed many software development tasks and template customizations for us. They took care of setting up our online marketing tools and campaigns, which we’re now able to run by our own staff efficiently. We can absolutely recommend Deniz Demirsoy and Dual Citizen other merchants.

  • LangerChenBusiness strategy guidanceMar 16, 2017

    LangerChen is a German-Chinese ecofashion brand producing sustainable jackets and coats. We were already selling our products globally through retail stores. Previously we were running our former website on Squarespace, a hosted content management system. Dual Citizen was recommended to us by one of their clients. Our experience with Dual Citizen was amazing. Literally within hours after launching our Shopify online store we got our first online customers. Dual Citizen definitely understands the specific business needs of a fashion brand. Instead of trying to tie us to longterm agency services contracts, they got us to a point where we can easily handle all e-commerce related operations by ourselves. Dual Citizen's services for LangerChen range from strategic business consulting to EU market specific adaptations, technical integration with our business operations and setting-up a new fulfillment infrastructure. We now understand the needs and habits of our end-customers better. Also, we're now expanding our business to areas where we didn't have any access to.
