Its covered companies include Metriport’s patient-data infrastructure, Light’s retail-energy systems and Delos Data’s inference infrastructure. Sila’s battery technology and Optura’s healthcare AI assessment remain separate company investments in the same firm history.
Delos Data builds an AI inference infrastructure platform spanning cluster software, server systems and data-interface silicon. It connects heterogeneous GPUs, accelerators, memory and storage into a resilient data domain so operators can scale inference workloads with lower latency and avoid interruptions when components or links fail.
