What Fundbook does

Fundbook is a Japanese M&A intermediary specializing in business succession and mid-market transactions, operating as a wholly-owned subsidiary of TSE Prime-listed Change Holdings Inc. The company serves two primary client cohorts: SME owners seeking succession or sale (sell-side), and growth-oriented companies, PE funds, and strategic acquirers seeking acquisition targets (buy-side). Its service architecture combines traditional advisor-led consulting with proprietary technology assets, most notably KEPL — an AI matching system built on a ~100,000-company database — and fundbook cloud, a public-facing online platform that publishes curated M&A listings for prospective buyers. Fundbook employs over 100 M&A advisors organized into industry-specialized teams covering manufacturing, construction, healthcare, eldercare, IT, food, energy, LP gas, and other verticals, supported by licensed professionals (CPAs, tax accountants, judicial scriveners) and a dedicated matching team. Operations are headquartered in Tokyo with a regional headquarters in Osaka covering western Japan.

Fundbook monetizes exclusively through transaction success fees (レセプター) charged upon M&A closing, with advisory contracts and initial business valuations provided free of charge to reduce client acquisition friction. Fee structures vary by deal size and complexity, and intermediate payments may apply in certain contract structures. The go-to-market motion is sales-led, centered on free initial consultations (in-person or remote) followed by financial diagnostics and full-process advisory through matching, top meetings, due diligence, and contract execution. Marketing is driven by content (M&A columns, industry-specific whitepapers, video gallery) and topical webinars targeting succession-driven sectors such as hospitals, clinics, and animal hospitals. Distribution is augmented by fundbook cloud's self-serve marketplace and a 2026 matching-donation partnership with UNHCR Association Japan that adds an ESG/social-return dimension to the sell-side value proposition. No standalone revenue, ARR, or transaction volume figures are publicly disclosed.

Emerging players

• M&A Research Institute: Tech-forward Japanese M&A intermediary leveraging AI and data-driven matching to win share against incumbents. Directly comparable to Fundbook's KEPL/fundbook cloud technology positioning in the Japanese mid-market.
• Traimmu / Japanese succession-focused intermediaries (e.g., 事業承継ラボ, M&Anexo): Emerging Japanese M&A intermediaries focusing on SMB succession with tech-enabled matching — directly comparable audience and product overlap with Fundbook's sell-side service.

Direct peers

• M&A Capital Partners: Listed Japanese M&A intermediary serving mid-market sell-side and buy-side transactions. Directly comparable business model with success-fee pricing, advisor-led delivery, and Japanese SMB customer focus.
• Strike Co., Ltd. Listed Japanese M&A intermediary with a strong advisor network and SME succession mandate. Competes with Fundbook for the same pool of Japanese SMB sellers and growth-stage buyers.
• Solar Consulting Co., Ltd. Listed Japanese M&A intermediary operating a network-based model targeting SMB succession and growth M&A, the same vertical Fundbook serves with its KEPL-powered advisor model.
• Nihon M&A Center: Japan's largest SMB-focused M&A intermediary with thousands of advisors and dominant market share. Several Fundbook senior advisors previously worked there, making it the most direct comparator in business model, customer base, and fee structure.
• M&A Total Consulting (Yamada Consulting Group affiliate): Japanese M&A intermediary operating within a larger consulting group. Offers comparable sell-side advisory, succession planning, and industry-specific M&A services to mid-market Japanese companies.

Others

• Change Holdings Inc. (parent / cross-sell partner): Parent company of Fundbook and operator of adjacent professional-services and IT businesses. Provides cross-sell and capital partnership rather than direct competition.

Broad incumbents

• KPMG FAS / PwC Advisory (Japan): Professional-services incumbents offering M&A advisory from a broader portfolio. Comparable at the upper end of Japan's deal-size spectrum, though they do not specialize in succession-focused SMB intermediation.
• Deloitte Tohmatsu M&A Advisory (Japan): Big-Four advisory practice in Japan serving mid- and large-cap M&A. Competes with Fundbook on larger and cross-border deals within Japan but lacks vertical-specific SMB succession focus.
