Xendit provides payment infrastructure across Southeast Asia, with a focus on Indonesia, the Philippines and Malaysia. We process payments, power marketplaces, disburse payroll and loans, provide KYC solutions, prevent fraud, and help businesses grow exponentially. We serve our customers by providing a suite of world-class APIs, eCommerce platform integrations, and easy to use applications for individual entrepreneurs, SMEs, and enterprises alike.
Our main focus is building the most advanced payment rails for Southeast Asia, with a clear goal in mind — to make payments across and within SEA simple, secure and easy for everyone. We serve thousands of businesses ranging from SMEs to multinational enterprises, and process millions of transactions monthly. We’ve been growing rapidly since our inception in 2015, onboarding hundreds of new customers every month, and backed by global top-10 VCs. We’re proud to be featured on among the fastest growing companies by Y-Combinator.
Experiments team builds growth engines for Xendit through experimental products. We do this by pushing the frontiers of what is possible in the industry and creating modern solutions to old problems. As part of the Experiments team, you may become part of a team that builds from 0 to 1, from 1 to 1,000, or 1,000 to the moon. It requires flexibility and adaptability to take on new challenges to grow an early-stage product.
To build from the ground up, we take ideas, customer pain points, or gaps in the market, push out an MVP at speed, and iterate to find product-market fit. This team presents a unique opportunity for people looking to build something new, rather than scaling mature products. People who join this team have a strong interest in growth (personally and professionally) and, therefore, a continuous improvement mindset.
