The Brief

What Callosum does

Callosum builds systems software that matches individual AI tasks to the most cost-effective and computationally efficient combination of models and silicon, an approach it calls heterogeneous intelligence.

Callosum's seed round was the first investment from the UK government's £500m Sovereign AI Fund, according to UKTN. The company, registered as Callosum Ltd in London, was incorporated in November 2024.
