Dipole Labs
Pre-seed · AI infrastructure
Dipole Labs builds optical circuit switches that keep data as light between GPU racks, targeting sub-microsecond reconfiguration so an AI cluster's network can reshape itself around each workload.
Wafer
Wafer builds AI agents that tune how open models run on NVIDIA and AMD GPUs, and sells the results as hosted inference.
Extropic
Extropic builds chips that use the thermal noise in ordinary transistors to sample from probability distributions, and says they can run probabilistic AI models on a fraction of a GPU's energy.
