What It Is

mastory.jp is an M&A and business succession information and lead-generation site operated by 株式会社M&A総合研究所. Its core offering is not a standard SaaS product, but an M&A advisory/intermediary service aimed at business owners looking to sell or transfer their companies. The company states that it is a subsidiary of クオンツ総研ホールディングス, with offices in Tokyo, Osaka, Nagoya, Fukuoka, Sapporo, and other locations, as well as an office in Singapore.

Core Capabilities

The service focuses on M&A intermediation, business succession, company valuation, and second-opinion services. Its selling points include end-to-end support from dedicated M&A advisors, legal support involving in-house lawyers, a nationwide network of tens of thousands of potential buyer companies, and a proprietary AI system that can instantly screen anywhere from 30 to several hundred buyer candidates. The site also states that it covers a wide range of industries, with deal sizes ranging from tens of millions of yen to tens of billions of yen, and cites performance metrics such as deals completed in as little as 43 days and an average completion time of 7.2 months.

Pricing and Support

The pricing model is relatively seller-friendly: it uses a pure success-fee model, with 0 yen for upfront fees, interim fees, and monthly retainers, and no charge before an M&A deal is closed. However, details such as the success-fee rate, minimum fee, and whether fees are calculated based on transfer price or asset value were not fully listed in the scraped content, so contract terms should still be carefully verified before formally engaging the service. For support, the company offers phone and web-based free consultations, as well as a customer inquiry channel that also accepts compliance-related concerns.

SaaS Evaluation

From an enterprise software perspective, the available information is clearly insufficient: there is no visible description of account systems, team collaboration, permissions, third-party integrations, APIs, cloud deployment, or self-hosting. On the security side, the site only confirms that inquiry forms use SSL communication, personal information is managed according to the privacy policy, and confidentiality is strictly maintained. As such, it is better understood as a high-touch professional service rather than a self-service deployable SaaS tool.

Pros, Cons, and Best Fit

Its strengths include low upfront cost, relatively comprehensive advisor and legal support, and broad buyer-network and case coverage. Its weaknesses are the lack of transparent fee details and the absence of software-style capabilities. It is best suited to owners of small and midsize Japanese companies, businesses without successors, and shareholders looking to sell a company or business unit. The text does not confirm accessibility from China; cross-border Chinese users will also need to consider Japanese-language communication, Japanese payment methods, and applicable Japanese law. If you need China-local M&A services, it may be worth comparing domestic financial advisors or industry-specific M&A platforms.
