By combining world-class design with world-class science and technology we are building tools that anyone can use to detect the earliest sign of life-threatening illnesses from the comfort and security of their home. They are accurate, easy-to-use, convenient and private. In other words, we are putting the human at the centre of everything we do.

Distilling Small Language Models for Enterprise. We distil enterprise-specific Small Language Models (SLMs) to achieve pinpoint accuracy with 10 – 100x cost savings. Malted AI combines enterprises’ domain expertise with our world-class knowledge distillation technology to solve the highest-value problems. Existing Large Language Models (LLMs) are overly general and lack specificity. Opposed to general AI that does thousands of tasks moderately well, Malted AI’s SLMs do one task near perfect.

Computers today compress reality to make sense of it. To model all the possible ways things can go wrong, they must do thousands of redundant calculations and the software they run must be modified to allow this. Signaloid’s compute platform is the next frontier in computing, available for use in production, today. It lets you see all the ways things can go wrong in calculations, orders of magnitude faster than any existing solution. Best of all, it runs your existing unmodified software. Running your mission-critical software on Signaloids compute platform allows you to be more confident when computers act autonomously. Our team consists of contrarian engineers with experience across organizations including Apple, NEC, IBM, University of Cambridge and MIT, among others.
