M&A matching system dev business, Kanagawa, full source code included

What is for sale

This business develops and sells a proprietary M&A matching platform system, customising a pre-built engine for corporate clients and people planning to start their own M&A matching services, rather than operating a matching site itself. It has generated cumulative sales of about ¥58,000,000 (57,912,000 yen) from 2019 to 2025 through system sales and customisation. The seller is divesting it to focus management resources on a new pet-related business they are launching, and is selling this and other businesses separately.

Because this is an asset (business) transfer, the buyer purchases the source code, rights and know-how only, and must set up their own contracts, accounts and any licences rather than taking over an existing company.

What is included

• Full source code of the M&A matching engine
• Design and specification documents
• Development and customisation know-how
• Transferable related intellectual property rights
• One custom-built M&A matching website delivered to buyer's specifications
• Option to continue outsourcing to the long-term engineer (SE) who built the system

Strengths (as the seller states them)

• Cumulative sales of about ¥58,000,000 from 2019 to 2025 selling and customising the system
• Using a pre-built engine shortens development time and delivery compared with building from scratch
• Full source code, related rights and know-how are transferred as one package, and the seller will not keep or resell the same engine
• A working demo site is available to check functionality and usability before buying, and a dedicated engineer can continue on contract after the sale

Wrinkles a careful buyer would ask about

• Continuity of existing customer contracts and recurring sales is not guaranteed by the seller
• Recently the business has focused mainly on maintenance for existing clients rather than active new sales
• The existing demo site itself is not included in the sale
• Exact scope and specifications of the one included custom website are still to be agreed in negotiation
• FY2026 (August) financial figures are not yet finalised, and detailed transfer-asset value is only visible to registered members

Paying for it

If you stay overseas. No Japanese bank will lend to a new company whose director lives abroad. The realistic stack is your own cash plus asking the owner to take part of the price over 2 to 3 years. That one question is in every Deal Pack.

If you move to Japan. On a visa that lets you run a business, Japan Finance Corporation lends up to ¥72M at about 1 to 2 percent for exactly this. Once you have a Japanese company, the government pays two-thirds of due diligence and registered-broker costs, up to about ¥8M (round 16 closes 6 Nov 2026). You start a bank relationship from zero.

What this listing says. The listing does not mention any debts, loans or personal guarantees transferring with the business; the asking price is ¥4,900,000 and TRANBI's broker success fee would apply separately, though no fee amount or minimum is stated in this listing.
