Why teams license from evlo.ai

The bottleneck in model quality is rarely the architecture, it is the data. We focus on the part that is hardest to fake: expert judgment.

Built by practitioners
Every task is authored by a verified specialist who does this work for a living, a clinician, an engineer, a lawyer, an analyst. Not crowd labour, not synthetic filler.
Reviewed before it ships
Each item is independently checked by a second expert and run through our automated quality gates, so what you receive is signal, not noise.
Ready when you are
Skip the months-long pipeline. Tell us the capability you want to move and we send representative samples the same week.

Dataset collections

Start from a ready collection or commission a custom set scoped to the exact capability you are trying to move.

Professional Judgment

Long-form, rubric-graded tasks that mirror the real decisions made by senior professionals across finance, law, medicine, and consulting.

ReasoningLong contextProfessional services

Coverage across 8 professional domains

Agentic Work

Multi-step tasks set inside realistic tool and file environments, measuring whether an agent can hold context and finish work end to end.

Tool useLong horizonAgentic

Workflows spanning engineering and operations

Grounded Retrieval

Open-ended questions that reward strategy, source navigation, and verification, and penalise confident guessing.

Web searchVerificationInstruction following

Multi-domain, real-world queries

Multimodal Reasoning

Tasks pairing text with documents, images, and structured data, built for models that need to reason across more than one input.
