What Portia does
Portia (株式会社portia) is a Tokyo-based Japanese B2B fintech company founded on February 22, 2016, that operates PortiaPAY, a B2B payment platform enabling invoice post-payment, QR-code-based cashless transactions, subscription billing, and API integrations for corporate commerce. The platform is delivered through multiple product modules — PortiaPAY ECommerce, Invoice, APPS, Register, Subscription, and Apps API — and is integrated with major Japanese B2B-EC infrastructure including EC-Rider, EC-Next, EC-CUBE, ecbeing, and CS-Cart. The company serves Japanese enterprises and SMEs needing digital alternatives to legacy phone/FAX-based ordering and manual invoice reconciliation.
Beyond payments, Portia operates three adjacent business lines: PortiaLyze, a real-time AI image and video analysis system using deep learning for healthcare, retail, infrastructure, and security applications; a web system development services practice building corporate and EC sites; and an offshore development lab providing Japanese-managed engineering capacity. In 2024 the company co-developed a BNPL integration plugin with AG Payment Service, and in August 2025 it formed an EC business partnership with Adaptive Inc. in Nagaoka to support regional SME digitalization. In September 2025 it launched glink, a foreign talent introduction service for IT and back-office roles.
The business model combines transaction-fee revenue on PortiaPAY, subscription/recurring revenue on PortiaLyze and PortiaPAY premium features, project-based revenue on web system development and offshore lab services, and emerging HR-introduction fees from glink. Distribution runs through direct enterprise sales, B2B-EC platform partnerships, and self-serve mobile app downloads on iOS and Android. The company is privately held with no disclosed funding rounds, registered capital of ¥40 million, reported 1-10 employees, and headquarters in Chiyoda-ku, Tokyo with a development center in Nagaoka, Niigata.
