Sheldon Group

Edward Hamburg's Sheldon Group is a single-purpose SPV formed in 2020 to back HerdDogg's animal traceability platform.

Sheldon Group

The Sheldon Group was established in mid-2020 in Delaware by managing member Edward Hamburg and associate managing member Rebecca Wetteman. The vehicle was created for the exclusive purpose of investing in HerdDogg, Inc., a company building a data-collection and analytics platform for animal traceability. The firm targets a single position in AgriTech, concentrating on HerdDogg's hardware and software stack that captures livestock data at the point of care. The investment spans hardware for location and health monitoring, digital record-keeping to replace paper processes, and an integrated marketplace for livestock. The opportunity is international in scope, applicable to cows, bison, and sheep. Confirmed co-investors in the HerdDogg round include Serra Ventures and Innova Memphis, both acting as lead investors. Sheldon Group operates as a special purpose vehicle with membership limited to qualified individual members. The firm's footprint is tied to HerdDogg's operations, which target beef producers domestically and in export markets where traceability unlocks premium program access. No additional offices, parallel investment vehicles, or philanthropic structures are currently disclosed. The firm's architecture is distinct in its single-asset concentration: Sheldon Group is not a diversified family office or a fund-of-funds but a purpose-built SPV for one deeply researched thesis in precision livestock management. Hamburg and Wetteman structured the entity purely to pool capital for the HerdDogg investment, with no disclosed mandate for follow-on funds or diversification.
