Launch HN: Discovered Materials (YC P26) – AI agents to discover new materials
Discovered Materials is a startup using AI agents to accelerate the discovery of thermally conductive dielectric materials for 3D chip packaging. The platform uses LLMs to propose materials and synthesis recipes, which are then graded by human experts.
Most energy loss in GPUs/AI accelerators today occurs due to the shuttling of data between memory and logic. To reduce the distance data needs to physically travel between the two, the industry is moving towards 3D packaging - stacking memory and logic wafers directly on top of each other, instead of spreading them out on a circuit board. Doing so would unlock 10-100x improvements in energy/bit for AI chips, but is bottlenecked by heat - poor heat conducting dielectric materials in the chip prevent the cooling of 3D chips, which makes them unviable.
