Investment thesis
The First Thirty backs companies applying deeptech and physical AI to human longevity and healthspan. Its thesis centers on new technologies that make biological quality measurable at the soil, plant and animal level, and that link this quality to nutrition, verify it, and carry it through the supply chain. When buyers can procure against biological quality, demand for health becomes an economic signal back to agriculture, shifting value toward nutrition and biological outcomes rather than only yield, uniformity and shelf life. The firm invests across the measurement, intervention, verification and data infrastructure enabling this, targeting the large healthspan opportunity driven largely by prevention.
