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.

Series B · Robotics and embodied AI

Generalist AI trains robot foundation models on more than half a million hours of human manipulation data collected with wearable grippers. It has raised about $700 million and was reported at a $3 billion valuation in August 2026, with no disclosed revenue.

Wafer builds AI agents that tune how open models run on NVIDIA and AMD GPUs, and sells the results as hosted inference.

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.

RadixArk is the company behind SGLang, the open-source inference engine, and sells managed infrastructure for serving and post-training open models.
