What the company does
Vanellus is building an autonomous thermal engineer for increasingly complex thermal design problems. Its proprietary GPU-native simulation engine makes high-fidelity thermal simulation faster, allowing engineers and AI systems to explore more potential designs. Vanellus plans to use insights captured from real customer workflows to develop an agentic system capable of repeatedly proposing, simulating and improving thermal designs.
