About Robert G
Robert G. Hisaoka is an individual investor based in McLean, Virginia, in the Washington DC metro area. A 2024 announcement of the Proxy Foods seed round described him as Chairman and CEO of RGH Capital.
Crunchbase lists RGH Capital as an investor in the HUNGRY Series C, with the firm as lead investor. Little else about his operating career or earlier roles is publicly documented, so this page does not list any.
Public databases show a small, concentrated record. Crunchbase lists two personal investments plus one investment made through RGH Capital. Tracxn dates his start in the startup ecosystem to 2021 through VLP Therapeutics and lists two portfolio companies, HUNGRY and VLP Therapeutics. Tracxn says he invests in companies across the United States and tags his sectors as Consumer, Life Sciences and three others it does not name.
Check sizes, ownership stakes and fund sizes are not public.
His AI investment on record is Proxy Foods AI, a Washington, DC company that builds an agentic AI platform for food and beverage product development and formulation. He was named among the investors in its $2.3M seed round in 2024, which Ted Leonsis led.
In August 2026 Proxy Foods AI announced a $6M seed round led by Ted Leonsis. Several press reports say Hisaoka and SWaN & Legend Venture Partners took lead participation. The company says it will use the money to expand its food science, regulatory and commercialization capabilities and to grow its global enterprise customer base. Its stated customers include Barilla, Gefsinus and CAVA.
The public record is thin, so this is only what the records show. His known investments span food and consumer (HUNGRY, Proxy Foods AI), life sciences (VLP Therapeutics) and applied AI for a traditional industry (Proxy Foods AI). Tracxn lists United States as his investing geography. His Proxy Foods AI position was in a seed round. HUNGRY was a Series C, made through RGH Capital. He has not published a check size range or an investment thesis that we could find.
