This latest transaction brings SAZO’s total capital raised to ¥3.97 billion.
Strong Performance Metrics and Operational Execution
The Series A capital injection follows significant operational momentum since the company’s ¥710 million Pre-Series A round in May 2025. Following the launch of its dedicated South Korean platform, SAZO expanded its infrastructure to enable seamless cross-border commerce for Japanese merchants targeting South Korean consumers.
- Gross Merchandise Value (GMV) Growth: Monthly GMV grew approximately 7x during the first half of FY26, achieving an 8-month CAGR of +39% month-over-month.
- Revenue Composition: Overseas buyers now account for 75.65% of overall platform sales volume.
- User Acquisition: According to company survey data, 47.71% of active users reported using cross-border e-commerce for the first time via SAZO’s platform.
Strategic Use of Proceeds
SAZO plans to allocate the newly acquired capital across three main growth vectors:
- R&D and "Agentic Commerce" Infrastructure: Developing autonomous AI agents capable of resolving cross-border friction. SAZO’s proprietary algorithm currently forecasts duties, shipping costs, and service fees with an estimated 95% accuracy rate, calculating localized end-prices automatically for buyers.
- Global Logistics Expansion: Expanding physical logistics centers and fulfillment networks beyond Japan and South Korea, targeting strategic market entry into the United States and broader international markets.
- Talent Acquisition: Scaling its current workforce of 65 employees across core functions including AI engineering, performance marketing, supply chain management, and business development.
