Gliese

What Gliese does

Gliese Co., Ltd. (株式会社グリーゼ) is a Tokyo-based BtoB content strategy partner founded in December 2000 by former Fujitsu system engineer Ejima Tamiko, who has led the firm continuously since establishment. The company specializes in producing what it calls 'primary information' (一次情報) — unique, enterprise-specific content drawn from expert interviews, case studies, and proprietary research that generative AI cannot replicate. Its core offering is project-based content production covering web content (interviews, reports, SEO-optimized articles), whitepapers, email marketing materials, and video, delivered through proprietary methodologies including the 'Vision Co-creation Type Case Studies' (ビジョン共創型導入事例) framework and a 5-phase 'Thought Leadership Practice Roadmap' designed to position BtoB clients as the cited original sources within AI-driven search results. Sales are conducted through direct consultation beginning with face-to-face or web meetings to understand client KPIs, personas, and customer journey before proposing tailored solutions, with a dedicated director managing each project end-to-end. Pricing is quote-based and not publicly disclosed.

The firm maintains a network of 40-50 external directors and writers that scales content production beyond a core team of 1-10 employees, with operations centered on a Nihonbashi, Tokyo headquarters and a secondary office in Naha, Okinawa. Target customers are Japanese BtoB enterprises seeking to establish Thought Leadership positioning and respond to the 'zero-click search' environment created by AI Overviews — a segment described in the firm's own 2026 survey, in which 36.6% of BtoB marketing professionals reported increased AI-search traffic versus 15.2% reporting declines. The company augments its consulting work with annual proprietary research reports, regular columns, and CEO-led seminar appearances (including a Turbine co-hosted seminar on AI-era BtoB web renewal), which serve as both demand-generation assets and third-party validation channels.

Gliese is privately held, founder-led, and has no disclosed external funding; it lists Shedar Co., Ltd. as a group company. The firm has no app, no API, no disclosed proprietary software platform, and no AI/ML technology stack. Its primary intangible assets are two named consulting methodologies, the founder's two-decade industry presence and editorial credentials (Nikkei MJ, ECzine, Web Writer Certification supervisor role), and an annual proprietary survey dataset. Competitive recognition includes a listing as a recommended SEO company for BtoB enterprises by Creative Bank's 'Digital化の窓口' portal.

Direct peers

• パンタグラフ (Pantograf): Tokyo-based content marketing agency specialized in B2B SEO articles, whitepapers, and interview-based content production. Directly comparable to Gliese in delivery model (interviews, research-backed content) and target buyer (B2B marketers in Japan).
• シンフォネット (SymphoneNet): Japanese content marketing agency offering content strategy, SEO articles, and whitepaper production for B2B clients. Compares to Gliese in service breadth (strategy + production) and domestic B2B segment focus.
• ferret one (Basic Inc.): Japanese B2B marketing platform combining content production, MA, and web tools with a content-marketing-as-a-service offering. Overlaps with Gliese on content strategy consulting and email-nurture execution for B2B clients.
• サムライト (Sumeru): Established Japanese B2B content marketing agency producing whitepapers, case studies, and lead-generation content for enterprise clients. Closely matches Gliese's service mix and primary ICP of mid-to-large Japanese B2B firms seeking authoritative, SEO-and-thought-leadership-grade content.

Broad incumbents

• HubSpot: Global marketing automation and CRM platform with an integrated content hub, ABM tools, and certified partner agencies that deliver content strategy and inbound services. Operates broadly across B2B content marketing and competes with boutique strategists like Gliese at the tooling and partner-program layer.
• 6sense: AI-driven ABM and revenue platform for B2B. Competes for the same strategic B2B marketing budget as Gliese, particularly in accounts pursuing ABM and AI-cited content strategies.
• Marketo (Adobe): Marketing automation incumbent (now part of Adobe) with deep email-nurture and lead-scoring capabilities. The same Marketing Cloud / Pardot certification held by Gliese's CEO signals adjacent competitive overlap with the platforms their strategies must integrate with.
• Demandbase: ABM-focused platform combining intent data, advertising, and sales intelligence with content activation tooling. Targets the same B2B CMOs Gliese serves, but at a tooling-plus-data scale rather than boutique consulting.

Regional players

• ノバセル (Novasel): Japanese marketing agency offering a broad mix of content, ads, and B2B lead generation services. Comparable as a domestic competitor for B2B content briefs, though broader in scope than Gliese's specialized AI-era focus.
• Brafton: US-based content marketing agency producing SEO articles, whitepapers, and email content for B2B clients. Comparable in deliverables and workflow to Gliese's content production services, though operating in North America/EMEA rather than Japan.
