Services

From raw data to a model you can trust

Five service lines built on one discipline: a trained, full-time team and a QA process that scores every delivery — from a single annotation batch to fractional data leadership.

01

Data Annotation & Labeling

The foundational work, across every modality — image, video, 3D, and text — labeled to the standard your model needs, at the volume your timeline demands.

Image annotation

Bounding boxes, polygons, keypoints, and classification at scale.

Video annotation

Object tracking and temporal attributes across frame sequences.

Image & instance segmentation

Pixel-level and instance segmentation for computer vision models.

3D point-cloud labeling

LiDAR and radar annotation for robotics, AV, and mapping.

Text & NLP annotation

Classification, sentiment, and instruction-following labels for language models.

Data cleaning & structuring

Turning messy, inconsistent data into something a pipeline can trust.

02

Data Validation & Quality

Human verification that catches errors before they reach your model. This runs under every service line by default — see the full process below — and stands on its own for teams that need a second, independent QA pass on data labeled elsewhere.

Gold-standard & consensus review

Every batch checked against benchmarks and cross-annotator agreement.

Error analysis & correction

Systematic review that catches drift before it reaches your model.

Class distribution & bias checks

Flagging skew and gaps a spec sheet alone won't catch.

Accuracy & overlap scoring

IoU and accuracy metrics on every delivery, not a spot-checked sample.

03

Generative AI & LLM Data

The same annotation and QA discipline, applied to prompts, responses, and preferences instead of pixels — the data work behind a model that actually behaves in production.

RLHF & preference ranking

Domain-informed ranking of model outputs for reinforcement learning and DPO.

Prompt & response evaluation

Fact-checking, instruction-following review, and rewrites that raise response quality.

Red-teaming & edge cases

Targeted prompts that surface where a model breaks before your users do.

GenAI system design

Architecture for LLM and generative pipelines — retrieval, evaluation, guardrails.

04

Data Science, ML & Analytics

Advanced analytics and machine learning aimed at one thing: moving your business toward a measurable outcome, not a research demo that stalls at the prototype stage.

ML proofs of concept

Fast, scoped demos that test feasibility before you commit to a build.

Analytics & data science

Turning operational data into decisions, not just dashboards.

Model evaluation

Structured testing of model output quality against your own criteria.

05

Capability Building

For teams that need senior data leadership or engineering support without a full-time hire — we step in as an extension of your team.

Fractional CDAO

Senior data & analytics leadership on a part-time basis — strategy, governance, roadmap.

DevOps support

Pipeline, infrastructure, and workflow support for data and ML systems.

Quality control

Quality isn't a promise here — it's a scored process

This is the part enterprise buyers usually ask about in diligence. Here's the actual mechanics.

Worker training

Task-specific, before live data

Annotators are trained on your task type and guidelines before they touch a single real record.

Qualification ranking

Higher stakes, proven annotators

Workers are ranked against task benchmarks, so the hardest edge cases go to the most qualified people.

Response scoring

Tracked through delivery

Every response is scored against your QA criteria on an ongoing basis, not sampled once at the end.

Pricing

How pricing works

We don't publish a rate card because scope varies too much to make one honest — but here's what actually drives the number, so you can size a project before you talk to us.

FactorWhat it changes
Task complexitySimple classification prices very differently from pixel-level segmentation or point-cloud labeling.
VolumeLarger, ongoing volumes bring the per-unit cost down — we price project-based work and standing pipelines differently.
TurnaroundStandard timelines cost less than compressed ones; we'll always tell you which lever moves the price.
QA depthHigher review thresholds (multi-pass scoring, senior QA) add cost but reduce rework downstream.
