Materials startup TBM acquires M&A broker Platinum Partners
What's the deal? TBM, the Tokyo-based materials company behind alternatives to plastic, has acquired all shares of Platinum PartnersDealroom has a profile for this one. Try Dealroom →, an M&A brokerage and business-succession advisory firm. The deal, announced in October 2026, was made through TBM's investment arm, TBM Investment, and its holding vehicle TBM PP Holdings. Terms were undisclosed.
What each side brings: Platinum Partners, also based in Tokyo's Chiyoda ward, advises small and mid-sized companies on M&A and succession planning — from valuation and finding counterparties to negotiating terms and post-deal handover. TBM works in GX deep tech, including new materials, carbon recycling, and plastic resource circulation.
Why now? Japan faces a wave of ageing business owners with no successors, leaving companies with strong technology, customers, and jobs struggling to pass the baton. TBM frames the acquisition as a way to help those firms transfer their businesses and keep growing.
What's the endgame? TBM wants to build a group of businesses that combine organically, adding external partnerships, investment, and M&A to its own product development. It has done this before, buying BioworksDealroom has a profile for this one. Try Dealroom → from a venture capital firm and investing its own resources to grow it.
What changes? Platinum Partners' current management stays in place and keeps running operations. The firm gains access to TBM's resources and domestic and international networks to expand its customer base, hire, and strengthen its deal teams. TBM says it will keep each deal's fairness and client interests front of mind.
The signal: A materials startup buying an M&A advisory firm is an unusual pairing, but it reflects a broader push to consolidate Japan's fragmented succession market. By pairing deal-making expertise with its own experience in business development and fundraising, TBM is betting that succession advisory can both generate pipeline and become a growth engine in its own right.
