Verified domain entities, institutional taxonomy & primary evidence nodes
Groundwork operates on a strict “Money after Math” doctrine. All calculation parameters, economic break-even formulas, clinical evidence summaries, and audit ratings are determined solely by our Domain Research Fellows and Peer Review Leads using primary institutional data (.gov, .edu, NIST, IRS, NREL).
Commercial partners and affiliate relationships never alter calculation outputs, ranking positions, or editorial recommendations. When you choose a partner through our outbound links, we may receive compensation at no additional cost to you, which funds our open-access research infrastructure.
