Why Coda
Coda is a global growth engine for commerce. We bring together powerful capabilities that connect people, digital products, and payments through our suite of trusted digital monetization and distribution solutions.
We recently acquired Recharge, Europe’s leading prepaid payments and digital gift card business, bringing both companies together into one organisation with broader reach, deeper capabilities across B2B and B2C commerce and a stronger global footprint.
Today, we stand as a team of more than 600 people, representing 57 nationalities across 23 locations. We are headquartered in Singapore with offices in Amsterdam, Dubai, Shanghai and other hubs across Southeast Asia.
Our B2B business works with publishers and brands to support growth across markets. We run Codapay for local payment acceptance and Custom Commerce for direct-to-consumer webstores. We manage catalogue, prepaid and distribution services that extend reach globally, and we operate Giftcloud’s rewards and incentives capabilities. We take on the operational complexity around payments, tax and compliance so partners can scale with clarity and focus.
On the consumer side, we operate a portfolio of trusted storefronts including Codashop, Recharge.com , Startselect.com , mobiletopup.co.uk and other local sites that give customers secure and easy access to digital credit, game vouchers, gift cards and prepaid products.
Our people are at the heart of what we do. Coda’s culture is centered on respect, clarity, ownership, and collaboration. We work hard and play hard together.
