Mashing Up

What Mashing Up does

Mashing Up is a Japanese-language online media platform operated by Mediagene Inc. as a vertical under the Business Insider Japan brand, focused on DEI (Diversity, Equity, and Inclusion), ESG, and sustainability topics. The platform publishes news, feature articles, and interviews targeted at corporate professionals, HR leaders, C-suite executives, and DEI practitioners in Japanese organizations seeking curated DEI/ESG coverage. It organizes content into three editorial pillars — DEI×Business, DEI×Society, and DEI×People — supported by recurring branded content franchises such as MOVE (enterprise diversity management), The Circle (DEI frontlines), Women Driving Change, Rethinking Gender, and Supporting Member Reports.

The platform's product surface extends beyond editorial into a series of online seminars/webinars (covering diversity management, organizational culture reform, and human capital management), the Mashing Up Accelerator program supporting female entrepreneurs with media exposure and pitch events, and a corporate Supporting Member sponsorship program. Distribution runs through the Business Insider Japan website (businessinsider.jp/mashingup/), email newsletters, and social media within the parent brand's ecosystem.

The business model is primarily advertising- and sponsored content-supported, with a Business Insider Japan PREMIUM subscription offering exclusive content and a corporate membership layer via the Supporting Member program. The platform does not disclose standalone pricing for paid offerings. No external venture funding, M&A activity, or independent revenue figures are evidenced; the property operates as a content vertical inside the Mediagene media portfolio.

Direct peers

• DiversityInc: US media and benchmarking platform focused on DEI in the corporate sector. Direct comparable in audience (HR leaders, DEI practitioners) and monetization (sponsored content, research, and corporate memberships), differing only by geography.
• NewsPicks: Japan-based premium digital business news platform with expert commentary and a paying subscriber base. Direct structural peer to Mashing Up as a Japanese-language premium content destination distributed through its own platform, though with a broader business-news remit.
• Sustainable Brands: Media and events platform serving sustainability-focused brand and corporate audiences. Comparable through its combination of editorial content, webinars, and supporting-member-style corporate engagement, much like Mashing Up's seminars and supporting members.
• GreenBiz: US-based digital media and events business covering sustainability, ESG, and the clean economy. Highly comparable to Mashing Up in combining editorial content, sponsored programming, and event/webinar monetization around an ESG/sustainability niche.
• TriplePundit: Online publication focused on ESG, sustainability, and social impact business news. Closely mirrors Mashing Up's mix of original reporting, interviews with corporate leaders, and sponsored content around DEI/ESG themes.

Broad incumbents

• Sifted: European digital business media outlet covering startups, sustainability, and workplace trends. Comparable as a digital-first business publication combining editorial, events, and sponsored content, though more tech/startup focused.
• Forbes Japan: Japanese edition of a global business media brand covering business, leadership, and increasingly DEI/ESG. Comparable as a broader business-news destination in Japan whose DEI/ESG coverage overlaps with Mashing Up's vertical.
• Nikkei ESG: ESG-focused editorial offerings from Nikkei, Japan's flagship business news publisher. Direct topical overlap with Mashing Up's ESG/sustainability coverage, but at vastly greater scale and as part of a broad incumbent.
• DIAMOND: Major Japanese business magazine and online outlet covering management, HR, and corporate governance. Overlaps with Mashing Up on HR/DEI/management coverage for Japanese corporate audiences, though as part of a much broader portfolio.

Emerging players
