About Howard Eisenberg
Howard Eisenberg is described in Proxy Foods AI funding announcements as a mentor at the Good Food Institute, a board member at Halcyon House, and the founder and former president of Eurosort and United Sortation Solutions.
PitchBook lists him as an individual angel investor and gives his role as CEO at United Sortation Systems. His company names appear slightly differently across sources, so founders should confirm details with him directly. Other public details about his career are limited in the sources reviewed.
PitchBook records one investment for Howard Eisenberg: Proxy Foods, dated 22 February 2024, in the business and productivity software category. That date matches the period when Proxy Foods announced a $2.3M seed round. Press coverage of that round names him among the other major investors.
He was named again in the 2026 seed round. No other angel investments were found in public sources, and he has not published a count of his investments.
Proxy Foods AI is a software platform for food and beverage research, development and commercialization. It uses agentic AI to predict how a formulation will perform, and it serves consumer packaged goods, foodservice and ingredient companies.
In August 2026 the company announced a $6M seed round led by Ted Leonsis. Eisenberg is named among the individual investors, alongside Jeff Skoll, Roger W. Ferguson Jr. and others. The Lounge deals desk lists two entries for this round, Proxy Foods Seed and Proxy Foods AI Seed, both $6M in August 2026.
Eisenberg has not published a thesis, a check size or a list of preferred stages. His one documented investment is an AI enterprise software company in food and beverage, backed at seed stage. His Good Food Institute mentoring suggests an interest in food systems, but that is an inference and he has not said it himself. His individual check size in Proxy Foods is not public.
