High quality datacomes from highlytrained evaluators

Data Gradient trains annotators to produce high quality data your models need now.

Staffing searchPlanned for teams

Search qualified people instead of resumes

Teams will be able to search the qualification record by task type, language and modality instead of interviewing their way through a spreadsheet of resumes.

Re-drill due

Scores come from graded practice on your rubric. Self-reported experience doesn't count. Every one is re-verified on a schedule you set.

01  The ideaN 01 / 06

We don’t want to train models. We want to train people.

Human data companies and AI labs work rigorously to post-train, fine-tune, and evaluate frontier models. Data Gradient applies that same level of rigor to training the workforce.

Mid-trainingFoundational courses built from guidelines on domain-specific corpora

02  Two tracks, one recordAnnotators → teams

Annotators build their credentials. Teams hire it.

The same qualification data serves both sides. Annotators earn a verified, portable record of what they can actually do. Teams will be able to search that record instead of interviewing their way through a spreadsheet of resumes.

03  For teamsSix reasons

Qualifications you can count on.

Built for the people accountable for batch acceptance: technical program managers, strategic project leads, delivery and quality leads.

01 / Build

Research becomes guidelines.

We take frontier research and turn it into guidelines.

02 / Gate

Credentials that matter.

If an annotator doesn't pass the threshold, they don't get a certificate.

03 / Search

We have the metadata.

We track everyone's ability by task type, language, and modality.

04 / Grade

Rubrics mean something here.

They mean everything. We take rubrics very seriously. Every task is answered in accordance with a clearly outlined rubric.

05 / Comprehensive

One program, many techniques

We plan to cover every modality known to man... in due time.

06 / Place

Partner and receive

If you partner with us on a course, you get vetted candidates from that course.

04  For annotatorsSix reasons

Training that labs actually need

We take state-of-the-art research and create training courses out of it. Learn also lists more than 1,200 jobs from human data companies and marketplaces, refreshed regularly.

01 / Learn

Courses for real work

We run our courses the way we ran our teams for the biggest frontier labs on the planet.

02 / Practice

Real tasks instead of quizzes

You do the actual task in the actual interface. Get it wrong here, where it costs nothing, instead of on a live batch.

03 / Improve

Get actual feedback

You don't just get a score. You get feedback on how you can improve.

04 / Qualify

The grade goes on your record

Each skill has a threshold. Clearing it goes on your record. Team visibility is planned.

05 / Keep it

Your credential follows you

It belongs to you and not to a company. Take it to the next project, the next human data company, the next lab.

06 / Stay connected

Stay in touch with your network

Even the best projects and clients can sunset their work. Stay in touch with the people who made it memorable.

05  The proofThree numbers

We reduce reworks, churn, and onboarding time

Training platforms usually report completions and seat time. Neither predicts whether a batch gets accepted. These do, and they’re the same numbers whether you’re staffing the work or doing it.

Cohort rework rate · % of tasks35170SESSION 01SESSION 124% GATE

Time to qualified

Days from first lesson to first accepted production task. The number that decides whether you can staff a project next week or next month.

First-pass acceptance

Share of work accepted without revision. We measure it in practice first so you know the answer before the client does.

Rework rate

The margin killer. Tracked per person, per task type, per error class, and traced back to the lesson that failed to land.

06  Questions05 entries

The things people
ask first.

It does what an LMS does: courses, enrollment, progress, and analytics. But that's the delivery mechanism and not the point. The product is qualification: practice environments that mirror production workflows, scored against the rubric the work will be graded on. If all you need is compliance training, a general-purpose LMS is cheaper and you should use one.

We believe in upskilling annotators for free. Learn also lists more than 1,200 jobs, imported from the public careers pages of human data companies and marketplaces and refreshed regularly.

We work together with your team to compose a workflow.

Annotators own their record. Teams see it only when it is shared with them.

We first understand your needs. We scope out the work. We build out the rubrics and tasks. We run the course together. You get a list of annotators to hire.
