What ZEROUM Co., Ltd. does

ZEROUM Co., Ltd. (ゼローム) is a Tokyo-based Japanese technology company founded on April 10, 2018, that operates a portfolio of creator-economy and digital-marketing businesses anchored on the Japanese live-streaming market. Its flagship product, Doneru (どねる), is a live-streaming extension tool that overlays follow notifications, chat, registration alerts, and tip-donation effects onto streams on YouTube, Twitch, and other platforms; the platform reached 330,000+ registered users by January 2026. The second product, VIRAL (バイラル), is a link-in-bio profile service for creators that bundles a digital fan-club card for monetization. The company also operates a portfolio of vertical web media properties led by ライブトレンド (Live Trend), described as one of Japan's largest live-streaming media sites with 400,000+ monthly unique visitors, alongside MediGlow, WEB TREND, and BUSINESS TIPS. A new beta service, VoicReq (ボイリク), a voice request product, was launched in November 2024.

The business model blends a freemium creator tool (Doneru basic features free with premium upsells), advertising revenue across its media portfolio, and a B2B web-consulting and digital marketing services line whose disclosed clients include Google LLC, Amazon Japan G.K., PayPal Pte. Ltd., and Zendesk, Inc. Distribution for creator products is product-led via web self-serve, while enterprise services are sold through direct field sales. Marketing leverages owned media (Live Trend and related properties), SEO, social channels, and flagship corporate sponsorships with J League Tokyo Verdy and Tokyo Verdy e-sports. The company is led by founder-CEO Yuji Wachi (和智 雄司), COO Katsuki Sakuragi (櫻木 勝貴), and CTO Kaito Yamashiro (山城 海人), and is headquartered in the Shinjuku Center Building in Tokyo. Strategic milestones include selection into the Microsoft for Startups program in December 2021, receipt of the 紺綬褒章 (Cordon Bleu Ribbon) from the Japanese Imperial Household and Prime Minister's Office in 2023, a capital and business alliance with Ceres Co., Ltd. in December 2020, and a joint VTuber agency LUMILIA launched with AdvanceGate in March 2020.

Direct peers

• Streamlabs (Logitech): Dominant global provider of streaming overlay, alert, and monetization tools integrated with Twitch and YouTube. Closest direct competitor to Doneru in the streaming-extension niche, with broader feature parity and larger installed base.
• StreamElements: Cloud-based streaming production and monetization platform offering overlays, alerts, tipping, and merch tools for Twitch/YouTube creators. Competes directly with Doneru on the core overlay-and-monetization workflow.
• Linktree: Global link-in-bio service used by creators to centralize social profiles and commerce links. Directly comparable to VIRAL, though Linktree is globally dominant while VIRAL is Japan-focused and adds fan-club card functionality.
• Lit.link: Japanese-origin link-in-bio service that aggregates social media profiles on a single customizable page. Domestic competitor to VIRAL with strong Japanese creator adoption.
• Bi.link: Japan-focused link-in-bio platform with profile, commerce, and creator monetization features. Competes directly with VIRAL in the Japanese creator market.

Regional players

• 17LIVE: Asia-Pacific live streaming platform with significant Japanese user base, providing tipping, virtual gifts, and creator monetization tools. Not a direct extension-tool competitor but a regional player in the same creator monetization category.
• Mildom (DMM): Japanese live streaming platform owned by DMM that integrates tipping, virtual gifting, and creator monetization. Comparable to the underlying platforms Doneru extends rather than a tool competitor.
• Pococha (DeNA): Japanese live streaming and creator monetization app operated by DeNA. Comparable as a Japan-focused live-streaming ecosystem player where Doneru's streamers are also active.

Broad incumbents

• Twitch (Amazon): The dominant Western live streaming platform and one of the two core platforms Doneru extends. Comparable as the underlying ecosystem whose policy and feature decisions shape Doneru's product roadmap.
• YouTube Live (Google): Google's live streaming service and the other primary platform Doneru extends. Comparable as a broad incumbent whose API and policy environment directly governs ZEROUM's product viability.
