Poolside Tech Stack

Foundation model developer building AI software agents for enterprises

Software Development San Francisco, California 51–200 employees Founded 2023 Privately Held

Poolside trains its own foundation models aimed at enterprise software agents, running a deep-learning stack of PyTorch, JAX, vLLM, Triton, CUDA and NCCL across GCP, AWS and Azure. Hiring tilts heavily toward engineering and data roles, and the project list centers on pretraining data: synthetic dataset generation, deduplicating web crawls and petabyte-scale streaming ingestion. That points to a team whose main bottleneck is data quality and throughput, not model serving.
