Callosum Raises $100M Seed Round for Multi-Chip AI Infrastructure
UK AI startup Callosum has raised $100 million in a seed round led by European VC Atomico, with significant participation from Plural, DCVC, and the UK's Sovereign AI, alongside angel investors. The company, founded by Cambridge neuroscientists, builds software infrastructure that allows AI workloads to run across different chips and AI models. Callosum challenges the industry's prevailing 'monoculture' belief that superintelligence will come from a single AI model running on identical chips. The startup argues that real-world problems are heterogeneous and require diverse computing capabilities. It also announced a partnership with US chip company Cerebras to integrate ultra-low-latency inference into its platform. Callosum previously raised $10.25 million in February 2026 when it came out of stealth.
