An agentic analytics platform that turns questions into governed, trusted answers
Ask a question in plain language and get a reasoned answer with the SQL, charts and tables behind it, available in the Hex workspace, in Slack and from developer tools.
Write SQL, Python and R side by side in one project, then turn cells into interactive, parameterised data apps and dashboards without a separate BI authoring tool.
Centralise metrics, semantics and corporate definitions so answers stay consistent, and see exactly where the agent lacked grounding so you can fix it.
Run graded, rubric-based test suites against the agent to measure answer quality and catch regressions as your data and context evolve.
The data, evaluations and systems behind AI that has to be right.
Human-sourced and expert-annotated training data, including specialist contributors with advanced degrees, at the quality bar frontier labs require.
Public leaderboards plus private benchmarks that test model capability and safety for the most ambitious AI developers.
Platform and services teams that pick the right use case, build the system and take ownership of the outcome.
Agentic systems designed around measurable business outcomes across private equity portfolios, energy and healthcare operations.
SpecialistStreamlines computer vision dataset annotation and model training, but is less suited for general LLM text tasks.


Focuses heavily on enterprise data labeling and training data curation, similar to Scale's core annotation business.
Faster for ad hoc statistical analysis and data visualization from natural language, but lacks Hex's robust notebook workflows.

Provides enterprise multimodal annotation and data management tools, but with less emphasis on managed labeling workforces.

SpecialistTrack, evaluate, and ship AI models and agents in one connected environment.


SpecialistFocuses on post-deployment LLM observability and evaluation rather than training data generation or annotation.
Specializes in data infrastructure and annotation specifically tailored for computer vision and physical AI workloads.

Free / Open-sourceOffers a flexible open-source alternative for custom data labeling and human-in-the-loop annotation pipelines.


SpecialistBuild, simulate, evaluate and monitor self-improving AI agents

SpecialistProvides LLM evaluation and testing workflows, but lacks Scale's massive human-in-the-loop data labeling services.

SpecialistOffers a spreadsheet-based interface with live data and Python execution, but lacks Hex's structured data app builder.
SpecialistConnects developers with verified human participants for RLHF and model evaluation studies instead of managed labeling.
