Online and Mail Order Retail Hanoi 201–500 employees Founded 2020 Privately Held

Crossian operates a DTC e-commerce business scaled across Vietnam and the Philippines, built on .NET Core, PostgreSQL, Kafka, and Kubernetes — a modern full-stack architecture typical of high-velocity consumer platforms. The hiring mix is heavily marketing-skewed (23 of 57 open roles), with active focus on ads optimization, creative testing, and global campaign scaling, suggesting a business model where customer acquisition and retention economics dominate the roadmap. Core pain points center on ROAS, LTV, and CPA efficiency, paired with operational friction around counterfeit listing removal and inventory at scale.
