Expanso

Expanso is the company behind Bacalhau, an open-source distributed compute orchestration framework that brings compute to the data by running jobs close to where data is generated across edge, on-premise, and cloud environments. Expanso Cloud is the managed platform for deploying intelligent data pipelines at the edge - filtering, transforming, and governing data (PII/GDPR compliance, lineage) before it reaches downstream platforms like Snowflake and Databricks. The Bacalhau Orchestrator API exposes job submission, execution history, results, log streaming, and node/agent management over a versioned REST interface. Expanso is backed by General Catalyst and was named Edge AI Startup of the Year 2026.

Expanso publishes 2 APIs on the APIs.io network: Ops API and Orchestrator API. Tagged areas include Company, Distributed Computing, Edge Computing, Compute Orchestration, and Data Pipeline.

Expanso’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, pricing, signup flow, and 17 more developer resources.
