Elementl

Elementl, Inc. is the company behind Dagster, rebranded as Dagster Labs in August 2023. Founded in 2018 by Nick Schrock (creator of GraphQL) and led by CEO Pete Hunt, the San Francisco company builds Dagster, an open-source, Apache-2.0 licensed, cloud-native data orchestration platform, and Dagster+, its managed cloud offering. Dagster's defining innovation is the Software-Defined Asset model, which treats data tables, ML models, and datasets as first-class, versioned objects with built-in lineage, data quality checks, and observability rather than as ordered task lists. The platform exposes a GraphQL API and a REST API for reporting external asset materializations, checks, and observations, plus Python and CLI clients. The company has raised roughly $48.8M, including a $33M Series B (2023) led by Georgian with participation from Sequoia, Index Ventures, Amplify, 8VC, Human Capital, Hanover, and Slow. The Dagster product API surface is catalogued separately in the api-evangelist/dagster profile.

Elementl is profiled on the APIs.io network. Tagged areas include Company, Open Source, Data Orchestration, Data Engineering, and Data Pipelines.

Elementl’s developer surface includes documentation, API reference, getting-started guide, pricing, signup flow, engineering blog, support, and 13 more developer resources.
