    Jefferson River Capital is one of two family offices financed by Hamilton (Tony) James, vice chairman for the Blackstone Group LP (see profile). According to Bloomberg, James's wealth, about $2.5 billion, is spread across at least two family offices, Jefferson River (see profile) and Swift River Investments. Jefferson River is named after a waterway that runs through his family's Montana ranch, and was set up in 2016. The firm has been involved with several small private equity transactions including: Autism Learning Partners, a Glendale, California-based therapy provider to children with autism spectrum disorders, and Portsmouth, New Hampshire-based Legacy Global Sports. Jefferson River also has participated in venture capital funding rounds, including those of Digital Asset Holdings, a financial technology firm led by former JPMorgan Chase & Co. executive Blythe Masters, and Pulmotect, which develops inhaled drug technology designed to boost immune response in lungs. According to Bloomberg, Jefferson River's real estate focus will be on multifamily, industrial and office properties in the Northeast and Southeast U.S.,
