Vast.ai Tech Stack

GPU compute marketplace connecting distributed hardware to AI workloads

Software Development Los Angeles, California 11–50 employees Founded 2018 Privately Held

Vast.ai operates a distributed GPU rental marketplace that undercuts enterprise pricing by aggregating consumer and data-center GPUs. The stack is GPU-native (CUDA, GPGPU, tensor libraries) paired with AWS data infrastructure (Redshift, Glue, Athena) and orchestration (Airflow, Dagster, dbt), revealing a company scaling both inference workloads and internal analytics. Active projects span kernel optimization, market pricing, and AI agent research — reflecting a platform caught between infrastructure efficiency and forward-looking AI capabilities.
