Overview
Integroup Inc. (インテグループ株式会社) is a Japanese company that provides M&A brokerage and advisory services, primarily targeting small and mid-sized enterprises (SMEs). The firm positions itself as a partner that connects the aspirations of business owners with future generations, emphasizing sincerity and close support throughout the M&A process. Its services cover sell-side support (company transfer), buy-side support (acquisitions), and management buyouts (MBOs). A defining feature of Integroup is its fully success-fee-based pricing structure (完全成功報酬制). Unlike many M&A intermediaries that charge upfront or interim fees, Integroup does not charge until a deal is successfully closed. The success fee is calculated either on a total transferred assets basis or a transfer price basis, with the company generally adopting the latter, which tends to result in lower fees. This model is presented as advantageous for business owners who are interested in M&A but still undecided, as they can explore options without financial risk. In recent years, Integroup has applied this fully success-fee model even to large deals with transfer prices in the tens of billions of yen. The company operates from a Tokyo head office and an Osaka office. It also runs "PEファンド.JP," a portal site launched in December 2020 that allows users to list and search buyout funds and their portfolio companies. Integroup publishes books on SME M&A and offers free corporate valuation services. Its leadership has authored works such as "The Truth About SME M&A" and "Inside the Mind of a Professional Negotiator."
