Arba Group
Arba Group is a multi-family office and investment firm headquartered in Tokyo, with additional offices across the United States, Brazil, Cyprus, and the Cayman Islands. The firm's founding year and principal operators are not publicly disclosed, though its structure as a multi-family office suggests it manages capital for multiple wealthy families, likely aggregating deal flow and co-investment opportunities. The firm deploys capital across private equity, venture capital, real estate, infrastructure, and private credit, targeting both direct investments and fund commitments. Its geographic breadth—spanning Japan, Brazil, the US, Europe, and offshore jurisdictions—enables it to pursue opportunities in technology, healthcare, climate, and real estate globally. Named portfolio companies or co-investors have not been publicly identified, but the firm's stated focus on AI/ML, enterprise software, and climate tech suggests a tilt toward growth-stage and venture-backed companies. Arba Group's team size and total deployment remain undisclosed. Its office network includes hubs in Silicon Valley, Los Angeles, Boulder, Seattle, and New York-area locations, alongside international bases in Sao Paulo, Nicosia, and Grand Cayman. The firm has not publicly disclosed any recent operational events within the last 24 months. The firm's structural differentiator lies in its multi-continent office footprint and multi-family office model, which allows it to source and co-invest across regions that single-family offices often cannot cover alone. This structure resembles a club-deal or co-investment network, though details on governance, succession, and fee structures are not public.
