Trusted by AI builders

Diraflow delivered STEM annotation quality we couldn't find anywhere else. Their mathematics contributors caught subtle errors that would have degraded our reward model significantly.

The agentic environment datasets they built were genuinely novel — not recycled from public sources. The quality bar is exceptionally high and turnaround was faster than promised.

From the field

AI safety researchers
Featured case study

Building 50,000 adversarial prompts for a frontier safety benchmark

A leading AI lab needed diverse, creative adversarial content that couldn't be generated by the model being tested. We mobilised 120 specialist contributors across 6 weeks to deliver an industry-defining safety benchmark.

From brief to delivery

01

Discovery & Scoping

A deep-dive call to understand your model, use case, quality bar, and timeline. We design the taxonomy and task spec together — collaboratively.

02

Expert Selection

We hand-pick contributors from our vetted network based on domain expertise, annotation style, and calibration performance on your task type.

03

Pilot & Calibration

A small pilot batch is reviewed together. We iterate on guidelines and calibrate contributors before committing to full production.

04

Production & QA

Full-scale production with multi-layer review, IAA monitoring, and weekly progress reports delivered directly to your team.

05

Delivery & Iteration

Versioned, documented datasets delivered in your preferred format. We remain available for follow-up batches and expansions.

We believe in human intelligence at the core

Synthetic data has its place — but the frontier of AI capability is still defined by the quality of human-generated signal. We exist to make that signal accessible, at scale, without sacrificing the nuance that makes it valuable.

  • Every dataset is built by humans — no AI-generated fill-in, ever
  • We publish our quality methodology openly — ask us for our QA framework
  • Contributors are paid fairly and treated as professionals, not gig workers
  • We maintain long-term relationships with contributors, ensuring consistency across your projects

Frequently asked

How do you ensure contributor quality?

Every contributor goes through structured onboarding: credential review, domain knowledge test, and calibration tasks scored against gold-standard examples. During production, we monitor inter-annotator agreement continuously and remove contributors whose scores fall below threshold. Project leads conduct spot checks at regular intervals.

What's the minimum project size?

We typically work best on projects of 1,000 tasks or more. For smaller exploratory pilots, we offer a structured 200-task pilot package to test fit before scaling. Get in touch and we'll find an approach that works for your situation and budget.

Can you handle confidential or proprietary content?

Yes. All contributors sign NDAs before accessing any project materials. We can work within your preferred data handling environment — including air-gapped annotation setups, your own VPC, or Diraflow's SOC 2-aligned infrastructure. Data security is standard, not an add-on.

How quickly can you start a new project?

For well-defined tasks with clear guidelines, we can typically begin a pilot within 5–7 business days of scope sign-off. More complex projects requiring custom tooling or specialised contributor recruitment may take 2–3 weeks to spin up. We'll give you an honest timeline during scoping.

Do you work with academic or non-profit research teams?

Absolutely. We work with research labs, universities, and non-profit AI organisations. We offer flexible engagement structures for academic budgets — reach out and let's talk about what's possible.

What data formats do you deliver in?

We deliver in whatever format your training pipeline expects — JSON, JSONL, CSV, Parquet, HuggingFace datasets, and more. Full schema documentation, versioning, and incremental or batch delivery depending on your workflow.

Can you guarantee zero AI-generated content in my dataset?

Yes. This is a foundational commitment at Diraflow — all work is produced by verified human contributors. Our QA pipeline includes AI-content detection checks, and any flagged output is reviewed and rejected before delivery. We can provide signed attestations on request.

How do you price projects?

Pricing depends on task complexity, required expertise, review depth, and volume. After scoping we provide a fixed per-task rate along with a total project estimate. We never upcharge mid-project — if scope changes, we re-quote transparently.

Do you support multilingual or low-resource language data?

Yes. We produce original human content in 30+ languages with native-speaker contributors. For low-resource languages, we work with in-region partners and linguists to maintain cultural fidelity and correct dialect handling.

Who owns the data once it's delivered?

You do. All deliverables transfer to the client on payment, with full IP assignment. We retain no rights to re-use, re-sell, or reference your data in other engagements.

Do you build evaluation harnesses as well as training data?

Yes. Many engagements pair training data with custom evaluation suites — including held-out benchmarks, scoring rubrics, and automated grading pipelines — so you can measure lift from the data you commission.

Can we work with a dedicated team across multiple projects?

Absolutely. For partners with recurring needs we set up a dedicated pod — a stable group of contributors, a lead reviewer, and a project manager — so institutional knowledge compounds across projects.
