The San Francisco Compute Company
The San Francisco Compute Company (SF Compute) runs a real-time marketplace for AI compute. It buys and operates large-scale, vetted GPU clusters - primarily Nvidia H100s wired with 3.2Tb/s InfiniBand - and sells them on flexible contracts, from a single hour to multiple years, that buyers can also resell. By turning long-term GPU capacity into a liquid spot market with transparent pricing, SF Compute lets startups, researchers, and enterprises buy exactly the compute they need without the multi-year commitments that dominate the industry, while pointing toward a future of cash-settled GPU futures.
Proficium, Inc.
Proficium is a Union City, California optical connectivity company that designs, manufactures, and tests the cables and transceivers that move data inside hyperscale and AI data centers. Founded in 2003 by Dan Miranda, it supplies OEM-compatible optical transceivers (400G, 800G, and 1.6Tb/s), DAC/ACC/AOC copper and optical cables, fiber assemblies, and InfiniBand interconnects validated against gear from Arista, Cisco, NVIDIA, and Juniper. An early mover in AI/ML cluster networking since 2019, the company was acquired by private equity firm Mill Point Capital in 2024 to scale with surging data center demand.
