Technology and AI

Simplexity pursues a fully proprietary technological approach. The base model named LaST combines world perception and prediction with a fast-slow thinking architecture in a vision-language-action concept, enabling the robot to respond in dynamic environments.

Market Significance

The company raised several hundred million US dollars within half a year and is considered one of the fastest-growing start-ups in the embodied AI sector. The first robot generation was manufactured in limited quantities, with initial focus on controlled scenarios such as factory halls, supermarkets, and logistics.
