SandboxAQ develops physics-grounded AI tools—centered on its ReAQT platform and Large Quantitative Models (LQMs)—that generate high-fidelity simulation data and predict properties of yet-to-be-synthesized materials. The company uses workflows such as AQCat and AQVolt to screen catalyst and battery chemistries with near-quantum-chemistry accuracy, and it has collaborated with NVIDIA on AQCat. SandboxAQ has published technical work in journals including Nature NPJ Computational Materials and Chemical Science. Its models are trained on the laws of physics, chemistry, and biology rather than human language, enabling virtual screening of millions of candidate materials to reduce lab trial-and-error. Following the CHIPS award, SandboxAQ plans to advance top candidates into scaled domestic manufacturing through American manufacturing partners and to invest the award funds into its platform and model enhancements.

Diamond Standard develops the world's only regulator-approved diamond commodities, packaging diamonds into standardized, transactable assets and blockchain tokens. The firm has launched the Diamond Standard Fund, Diamond Standard Bar, and the Diamond Standard Coin to give investors convenient exposure to diamonds. It aims to position diamonds as a new, uncorrelated asset class and has agreements to develop diamond futures via MGEX on the CME Globex platform and options via MIAX. To meet growing investor demand the company is expanding production capacity, hiring aggressively, and building a new Bar assembly facility in collaboration with the International Gemological Institute. Diamonds are graded by the Gemological Institute of America and the International Gemological Institute, and company operations are internally audited by Deloitte. Company executives reported the Diamond Standard Coin returned 20% last year and has continued to generate positive returns this year.
