Clockwork.io raises $31M for AI workload resilience
Clockwork.io raised $31 million as LinkedIn and Together AI deployed its fault-tolerance software in production, with WhiteFiber expanding use, the company announced. LinkedIn says it prevents tens of thousands of GPU-hours of downtime monthly; new TorchPass features add whole-job snapshots without training-code changes. The savings claim is customer-reported, but it highlights a direct cost lever for teams renting large clusters: reduce failure recovery and repeated work before buying more capacity, a utilization risk also visible in the economics of CoreWeave’s GPU-cloud bet.
