Callosum vs Manus AI
Side-by-side comparison of AI visibility scores, market position, and capabilities
Callosum (London) raised $10.25M for multi-vendor AI chip orchestration — unifying GPUs, TPUs, and custom silicon — founded by Cambridge neuroscientists. Feb 2026.
About
Callosum is a London-based AI infrastructure startup founded by Cambridge neuroscientists who applied their understanding of how the brain orchestrates computation across specialized regions to the problem of multi-vendor AI chip coordination. The company's name references the corpus callosum—the brain structure that connects and coordinates the two cerebral hemispheres—reflecting its technical mission: enabling different AI accelerators from different vendors to work together efficiently as a unified compute resource. Callosum addresses a real pain point for enterprises and cloud providers that now operate heterogeneous fleets of GPUs, TPUs, and custom silicon.\n\nCallosum's orchestration platform abstracts over hardware differences between AI chip vendors, allowing workloads to be scheduled and balanced across NVIDIA, AMD, Intel, and custom accelerators without manual optimization for each chip type. This is particularly valuable as enterprises seek to reduce vendor lock-in and optimize cost by mixing and matching hardware. The platform targets ML engineering teams and infrastructure operators at companies running large-scale AI training and inference workloads who need to maximize utilization across a diverse hardware estate.\n\nCallosum raised $10.25M in February 2026 in a seed or early-stage round, providing capital to build out its engineering team and deepen integrations with major chip platforms. While early in its journey, the company operates at a genuinely important intersection: as AI chip diversity grows and no single vendor dominates all workloads, the need for intelligent multi-vendor orchestration will only increase. Callosum's neuroscience-rooted technical vision and Cambridge pedigree give it a distinctive angle in the competitive AI infrastructure space.
