Grafton Sciences Tech Stack

AI systems with physical embodiment for manufacturing and experimental science

Robotics Engineering Redwood City, California 11–50 employees Founded 2024 Privately Held

Grafton Sciences combines robotics hardware (STM32, ESP32, ROS) with formal reasoning and knowledge graphs (Neo4j, TigerGraph, Z3, Coq, TLA+) to build AI systems capable of autonomous physical experimentation and manufacturing. The stack reveals a company bridging symbolic AI (ontology, formal verification) with embodied robotics—a rare pairing that reflects their stated goal of grounding superintelligence in physical substrate. ARPA-H backing and a senior-heavy team of six focused on ontology, knowledge graphs, and robotic integration suggest deep technical complexity rather than product velocity.
