NAVER D2SF has invested in SAZO, an AI-powered cross-border e-commerce startup that automates shipping cost and tariff prediction, translation, pricing, payment, and customs clearance. The startup operates a Korea–Japan service that has grown its monthly transaction volume approximately 7× in the recent 6 months.
Why it matters
Cross-border shopping is a major growth area—59% of the world's consumers have purchased from overseas retailers—yet language, payment, currency, and customs rules create friction. SAZO aims to solve this by predicting shipping and tariff costs with about 95% accuracy and automating the entire transaction, letting both consumers and platforms expand into new markets without building separate systems or managing overseas inventory.
What to watch
SAZO currently operates in Korea, the US, and Japan, with plans to expand its service to more countries. It has already partnered with Mercari, Rakuten, and Bungaejangter, and is in discussions with NAVER Shopping on multiple forms of cooperation.
