RBG Partners

Investment decisions sit with the two named co-heads, 金子英正 and 時田太郎. The firm's website does not detail an investment committee structure beyond the co-representative model, suggesting a flat senior decision layer characteristic of small independent sponsors.

The firm targets the classic Japanese independent-sponsor pipeline: succession-driven sellers, corporate carve-outs, and underperforming subsidiaries. Sourcing relies on the partners' networks with regional banks, corporate advisors, and intermediary professionals, rather than broad auction participation.

RBG Partners does not disclose a traditional blind-pool fund. Its portfolio includes an entity named 株式会社RBGP1, used as a holding vehicle for a solar investment, consistent with independent sponsors that raise capital on a deal-by-deal basis through special-purpose vehicles.

The firm covers buyout, divestiture, growth, restructuring, spin-off, and succession transactions, per the Altss-curated strategy tags. This wide mandate is typical of small Japan-focused sponsors that match their engagement to the specific transition need rather than imposing a single-stage template.

Disclosed portfolio companies cover industrial technology (アルメックステクノロジーズ), precision tools (ミニター), healthcare services (タイムウェルメディカル), biotech CDMO (S.H.Iバイオ), renewable energy (RBI SOLAR), facility services (ウィズコーポレーション), media/entertainment (アベックス) and telecom/energy (Grancell) — no sector is explicitly excluded, though the firm appears generalist.
