Septeni operates via a dual-pillar structure: a Digital Marketing Business and a Media Business, unified by the Septeni Model that combines data science with creative production to deliver measurable client outcomes.

Media Business

Operates GANMA! as an IP incubator and manga distribution platform, enabling content creation, audience growth, and direct user monetization across digital channels.

Septeni Model

Partnerships & Reach

The company structure and operations focus on capturing value across the ad tech and media stack, converting creative IP into monetizable audiences while driving measurable ad performance; in FY2024 digital ad-related services and media IP contributed materially to consolidated revenue growth.

Septeni Holdings’ revenue model is led by its Digital Marketing Business, which generated approximately 88% of group revenue in fiscal 2025; the Media Business supplied the remaining 12%, creating a dual-engine monetization mix focused on ad commissions, recurring fees, subscriptions and IP licensing.

Digital Marketing: Core Revenue

Commission-based advertising and recurring consulting/data management fees drive the Digital Marketing Business, with transaction volume near 118 billion JPY in 2025.

High-Margin DX Services

Shift to data transformation (DX) services increased average client ARPU as clients moved from standard ad ops to premium analytics and platform integration contracts.

Advertising Commissions

Performance and placement commissions remain a primary income stream, with programmatic and direct-sold inventory forming the bulk of ad revenue.

Media Business Growth

The Media Business, led by platforms like GANMA!, contributes about 12% of revenue via ads, subscriptions and IP monetization.

Subscriptions & Premium Content

Monthly subscription fees for premium content provide predictable recurring revenue and higher lifetime value per user.

IP Licensing & Cross-Sell

Licensing original IP for anime, merchandising and film, plus cross-selling media insights into client marketing, captures value across the digital value chain; see Marketing Strategy of Septeni Holdings.

Revenue diversification supports margin resilience: advertising commissions and transaction-driven fees dominate top-line generation while DX and subscription offerings improve margin profile and recurring revenue share.

Septeni’s shift into Dentsu’s group by 2022—operationally mature by 2025—transformed its scale and client access, while rapid Southeast Asian expansion and a proprietary first-party data solution after 2024 fortified its international revenue and privacy-proofing.

Key Milestone: Dentsu Consolidation

The 2022 transition to a consolidated subsidiary of Dentsu completed operationally by 2025, unlocking blue-chip clients and a global media network that addressed prior scale limits.

Strategic Move: Regional Expansion

Aggressive Southeast Asia expansion established regional hubs that now account for a materially growing share of international revenue, diversifying Septeni’s geographic footprint.

Privacy-Driven Innovation

In response to the 2024 global privacy shift and third-party cookie deprecation, Septeni launched a first-party data solution that became a primary competitive advantage and revenue enabler.

Technology & Platform Ownership

Owning media platforms like GANMA! allows Septeni to pilot ad tech innovations internally before client rollouts, supporting faster product-market fit and measurable performance gains.

Financial and operational implications of these moves include improved margins, scalable service delivery, and resilient revenue streams aligned with evolving ad tech trends.

Competitive Edge & Operational Highlights

Septeni’s hybrid business model, tech leadership, and Dentsu economies of scale underpin a differentiated value proposition in digital advertising and marketing services.

• Technology-first testing via owned platforms reduces time-to-market for new ad products and improves ROI for clients.
• Economies of scale from the Dentsu alliance enable competitive pricing while preserving operating margins near 14 percent.
• First-party data solution mitigates privacy regulation risks and supports sustainable audience targeting post-cookie era.
• AI-driven automation shifted staff from manual execution to strategic consulting, protecting revenue against commoditization.

Septeni holds a leading position in Japan’s digital marketing sector, ranking among the top three specialized digital agencies by transaction volume and expanding market share in 2025 as smaller rivals fall behind on AI and data infrastructure investment.

Industry Position

Septeni’s business model centers on integrated adtech, data services and creative production, supported by subsidiaries across media, performance marketing and platform partnerships.

Market Footprint

In 2025 the company leverages scale to serve large advertisers within Japan’s 3.6 trillion JPY digital advertising market and reported continued revenue momentum entering FY2026.

Key Risks

Generative AI evolution and regulatory scrutiny on data privacy present material operational risks, while dependence on major ad platforms like Google and Meta is a systemic vulnerability.

Financial Position

Management projects a 9 percent revenue growth rate for the upcoming fiscal year and cites a strong balance sheet to fund AI and clean-room investments.

Septeni’s 2026 Vision repositions the group toward Marketing DX and business transformation services, with strategic moves like deeper AI in GANMA! content and expanded data clean room offerings to address a cookie-less ecosystem.

Strategic Outlook

Execution priorities are AI integration, platform diversification and selling higher-value transformation engagements to reduce reliance on third-party ad channels.

• Invest in proprietary AI and data infrastructure to protect market share and improve margins
• Expand data clean room capabilities to support privacy-compliant targeting and measurement
• Shift revenue mix toward recurring transformation and SaaS-style services
• Pursue partnerships to mitigate concentration risk tied to major ad platforms
