AI Compute Platform Callosum Raises $100M Led by Atomico

The raise signals that investors see orchestration, not just silicon, as a bottleneck in AI compute — a layer where multi-chip scheduling could matter as hardware supply stays constrained. It puts Callosum in the same conversation as other well-funded infrastructure plays competing for enterprise and cloud workloads. Whether that capital translates into durable adoption, rather than another crowded infrastructure bet, is the open question worth watching.
