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 Pipeline.

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

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/elementl: open an issue to ask a question, or submit a pull request to add artifacts. Submit an artifact on GitHub — free → Manage your own listing — the Influence plan, $499/mo →
