01 / SERVICES

Your capability goal.
Our data program.

Expertise, production infrastructure and quality controls, brought together around the capabilities you need to build.

Pilot / Scale / Continuous supply
01

Post-training data

Instruction-response pairs, expert solutions, preference feedback and multi-turn interactions for SFT, RLHF and other post-training approaches.

02

High-difficulty expert data

Researchers and domain specialists design, produce and review work that requires deep subject knowledge and rigorous problem-solving.

03

Model & agent evaluation

Evaluation sets, task design and scoring criteria for reasoning, tool use, task execution and stability across extended workflows.

04

Custom data solutions

Data specifications, difficulty distributions, production processes, quality metrics and delivery formats tailored to your model and product.

05

Data quality operations

Cleaning, structured parsing, deduplication, format validation, multi-level review and post-delivery processing supported by our own tools.

02 / DELIVERY STRUCTURE

More than answers.
Data you can work with.

From task context to expert review, configure the evidence and metadata your training or evaluation pipeline needs.

CODING AGENT / DELIVERY DESIGN

Executable work. Verifiable results.

Build datasets around repository context, realistic engineering tasks and evidence that the outcome works.

  • Software engineering and web development
  • Research reproduction and scientific workflows
  • Operations, terminal tasks and controlled security tests

SFT: instructions and expert responses · RLHF: preferences and scoring · Agents: interactions and tool trajectories · Evals: tasks and rubrics

04 / QUALITY & DELIVERY

Quality is a process.
We build it in.

Automated checks and expert judgment work together, with clear responsibilities from contributor qualification to final acceptance.

01

Qualification

Assess domain knowledge and task readiness.

02

Calibration

Align contributors on standards and examples.

03

Sampling

Monitor production and correct quality drift.

04

Expert review

Check professional accuracy and consistency.

05

Lead review

Resolve complex issues with subject leads.

06

Acceptance

Validate format and agreed delivery criteria.

07

Trace & improve

Find root causes and update the process.

Infrastructure for scale.

Our own task management and data tools support assignment, production monitoring, automated validation, quality reporting and version control.

Confidentiality, throughout.

Project-specific controls protect client data, model information and working materials across the delivery lifecycle.

  • AgreementsEmployment, confidentiality and project-specific terms.
  • AccessPermissions matched to project roles and requirements.
  • HandlingDevice, file transfer and local storage controls.
  • CloseoutArchiving or secure deletion as instructed by the client.

Quality is linked to contributor compensation, incentives and future task eligibility. Sampling, cross-review, blind review and consistency checks are configured for each project.

05 / WORK WITH US

Scope / Sample / Calibrate
02 / SCALE

Project delivery

Draw on experience delivering multiple large-scale data projects, with dedicated leads, parallel production and phased acceptance.

Staff / Produce / Deliver
03 / KEEP BUILDING

Ongoing partnership

Maintain a steady supply as your models evolve. Adjust task coverage, difficulty and standards through recurring feedback and direct team access.

Supply / Evaluate / Iterate
A practical starting point for your next data program.
What to prepare for a scoping conversation
  • Model or product focus and current capability gaps.
  • Training approach: SFT, RLHF, other post-training or evaluation.
  • Task types, disciplines, difficulty and language requirements.
  • Expected volume, batch schedule and target delivery dates.
  • Sample records, required fields and acceptance criteria.
  • Data formats, usage rights and confidentiality requirements.
