What Upsider does

UPSIDER is a Tokyo-based B2B fintech founded in May 2018 by Miyagi Toru and Mizuno Tomonori that operates an AI-powered corporate payment and financial services platform for Japanese startups, SMEs, and listed enterprises. Its core product is an AI-issued corporate credit card (Visa) that uses a proprietary credit model trained on real-time bank API transaction data to extend credit limits of up to 10 billion yen — well above conventional Japanese corporate cards — with automated initial decisions in seconds and no annual or issuance fees. The platform extends across PRESIDENT CARD (premium executive card with JAL mileage and Dragonpass lounges), Shiharai.com (invoice card payment service jointly operated with Credit Saison that extends payment terms up to 60 days), the UPSIDER BLUE DREAM Fund (a 243 billion yen venture debt fund operated by UPSIDER Capital, the largest independent venture debt fund in Japan), UPSIDER AI Accounting (subscription BPO from 9,480 yen/month), the UPSIDER Coworker chatbot for Slack/Teams, and a white-label external card infrastructure platform launched in July 2025.

The company monetizes through multiple streams: card interchange and point rebate economics on transaction volume (cumulative card volume exceeded 8,500 billion yen by November 2025 across 100,000+ registered companies), transaction fees on Shiharai.com (1,500+ billion yen cumulative), interest and origination fees on venture debt (130+ billion yen disbursed at average ~400 million yen per loan), subscription fees for AI Accounting and PRESIDENT CARD annual fees, and an emerging licensing stream from white-label infrastructure partners. Distribution is hybrid: PLG-style self-serve web onboarding for startups/SMEs, Mizuho Bank's 560,000-client corporate sales network (following Mizuho's July 2025 acquisition of ~70% of UPSIDER Holdings for ~46 billion yen), partner channels through freee-certified accounting firms and Rakus/Rakuten for Shiharai.com white-label, and direct executive sales for PRESIDENT CARD.

As of July 2025, UPSIDER reported an annual revenue run rate of approximately 10 billion yen with 50%+ YoY growth. Founders retain operating control post-Mizuho acquisition and have stated intent toward a future IPO. The company holds PCI DSS v4.0.1, ISMS (IS 799150), and JIIMA electronic invoice certifications, and is supervised as a third-party prepaid payment instrument issuer by the Kanto Finance Bureau.

Direct peers

• Brex: US-based AI-powered corporate card and spend management platform targeting startups and growth-stage companies. Closest international analog to UPSIDER: similar AI credit underwriting, similar customer segment (tech startups), bundled spend management and bill pay, and venture debt adjacent offerings.
• Ramp: US corporate card and finance automation platform with AI-driven receipt parsing, expense automation, and bill pay. Directly comparable to UPSIDER on product breadth (card + AI accounting automation) and SMB/mid-market targeting, though without a venture debt fund.

Broad incumbents

• Stripe Issuing: Stripe's embedded card issuing platform that allows businesses to create and manage branded cards. Directly comparable to UPSIDER's External Corporate Card Infrastructure (white-label platform) launched July 2025, though Stripe Issuing is broader in scope.
• Money Forward: Leading Japanese cloud accounting and fintech SaaS provider. Directly overlaps with UPSIDER's AI Accounting BPO offering and Shiharai.com ecosystem, and is one of UPSIDER's API integration partners. Comparable on the SMB finance automation layer of the stack.
• freee: Japanese cloud accounting SaaS leader and UPSIDER's distribution partner via the freee AI BPO program. Overlaps with UPSIDER AI Accounting service and serves the same SME customer base with complementary accounting and HR products.
• Mitsubishi UFJ Nicos: Major Japanese credit card issuer jointly owned by Mitsubishi UFJ Financial Group. Comparable as an established card issuer for both consumer and corporate customers, providing scale and incumbency benchmarks against which UPSIDER's differentiation must be measured.

Regional players

• Credit Saison: Japanese credit card issuer and Shiharai.com joint operator with UPSIDER. Comparable as a card issuer infrastructure partner and a broader consumer/SME card business in Japan, with overlapping service categories in card issuance and point programs.

Emerging players

• Kyash: Japanese fintech offering consumer and business prepaid/credit card products. Comparable as a Japanese fintech targeting payment modernization and SME expense management, though smaller scale than UPSIDER and more consumer-tilted.
• Net Protections (NP後払い): Japanese BNPL and B2B invoice financing provider, including invoice card payment and post-payment services. Directly comparable to UPSIDER's Shiharai.com invoice card payment service in product and target market.
• Plastiq: US-based B2B payment platform enabling businesses to pay invoices via credit card. Closest international analog to UPSIDER's Shiharai.com, addressing the same pain point of extending payment terms on bank-transfer invoices through card-based financing.
