London startup Callosum, which builds software to match AI tasks with the right models and chips, secured a $100 million seed round from Atomico, the UK Sovereign AI Fund and other investors.
London‑based startup Callosum has secured a $100 million seed round, the company announced, with backing from venture firm Atomico, the UK Sovereign AI Fund and additional investors. Callosum builds software that dynamically matches specific artificial‑intelligence workloads to the most suitable combination of models and hardware chips, aiming to optimise performance and cost across diverse AI tasks.
The sizeable seed round signals strong investor confidence in orchestration tools that can navigate the increasingly fragmented AI ecosystem. As enterprises juggle a growing catalogue of foundation models and specialised accelerators, software that can automatically route jobs to the optimal compute resource promises to reduce latency, lower energy consumption and simplify deployment. By abstracting the choice of model and chip away from developers, Callosum could lower barriers to entry for firms that lack deep expertise in AI infrastructure.
The funding will be used to accelerate product development and expand the team, positioning Callosum to compete with other emerging AI‑task scheduling platforms. Observers will watch how the startup integrates with major cloud providers and chip manufacturers, and whether it can secure early‑stage customers seeking to streamline multi‑model pipelines. The round also underscores a broader trend of capital flowing into infrastructure layers that enable more efficient use of the AI model and hardware market.
