Parasail
Parasail is a San Mateo-based AI inference cloud that lets developers run open-source and custom models without buying or committing to their own GPUs. Instead of owning chips, it orchestrates rented GPU capacity across roughly 40 data centers in 15 countries plus its own clusters, automatically routing each workload to the cheapest, fastest hardware. Founded in 2023 by Mike Henry (ex-Groq CPO, Mythic founder) and Tim Harris (Swift Navigation founder), the company processes on the order of 500 billion tokens a day and pitches a token-based economy - pay for output, not hardware.
Zyphra
Zyphra is a superintelligence research and product company building efficient, open foundation models and a full-stack AI cloud. Best known for its SSM-hybrid Zamba models, the ZAYA1 reasoning family trained entirely on AMD hardware, and the Zonos text-to-speech system, Zyphra argues that frontier intelligence should run cheaply, locally, and outside the walled gardens of a handful of labs. In June 2025 it raised a $100M Series A at a $1B valuation led by Jaan Tallinn.
