CONSULTING DIVISION

Consulting

From TSE Prime-listed companies to seed-stage startups and century-old businesses.
What B supply faces are the management issues that decide a company's growth.

We don't stop at drawing strategy: we sit beside executives, support decisions and execution, and stay until it turns into results.
Work from anywhere — Osaka HQ or fully remote, in an environment built for work that matters.

INVESTMENT DIVISION

Principal Investment

We invest B supply's own capital in SMEs with distinctive technology, customer bases, and business assets.
From sourcing to the investment decision, post-succession management support, and growth execution — this is the work of creating a business's next possibility.

After investing, we face the business as principals of its management, not as outside advisors.
Depending on your experience and results, there are opportunities to join portfolio companies as a director, executive officer, or business lead.
