Sail Research, founded in 2025 in San Francisco, USA, provides inference infrastructure and sandbox environments (Sailboxes) for long-horizon AI agents, rebuilding the inference stack from the chip level up and claiming up to 10x reduction in per-token cost.

Inference.net is a San Francisco-based AI inference infrastructure company. It began in early 2024 as Kuzco, a Solana-based decentralized network aggregating idle GPU compute for LLM inference, and rebranded in mid-2024. It now offers an LLM lifecycle product suite (Deploy, Observe, Trace, Train, Evaluate) that lets AI-native teams run open-source and custom models at lower cost than proprietary APIs.

RadixArk, founded in 2025 in Palo Alto, California, USA, develops AI systems around the SGLang inference engine and Miles reinforcement learning framework, improving model inference and training efficiency by reducing compute and memory requirements.

Baseten, founded in 2019 in San Francisco, USA, helps customers access pre-trained open-source or custom AI models, enabling developers to build and deploy AI applications.

Infinity, founded in August 2025 by former Google Brain researcher and AGI House co-founder Jeremy Nixon, builds a universal inference software layer for heterogeneous AI chips. Its autonomous agent Ignition automatically generates, tests and optimizes the low-level compute kernels that determine how efficiently a chip runs AI models — positioned as a CUDA alternative — and already works with chipmakers such as d-Matrix with several million dollars in ARR.

Decart, founded in 2023 in Tel Aviv, Israel, improves the efficiency of AI models to enable faster and more reliable training and real-time inference. Its diffusion model can generate video in real time as users watch; its model powers the open-world video game Oasis, rendering new portions of the game world in real time based on player movement inputs.
