Data, made
with intent.
We design, build and curate the training and evaluation datasets that models actually learn from.
Most AI problems are data problems in disguise.
New data, from scratch
When the data you need doesn't exist, we build it: expert-written examples, carefully captured images and video, and synthetic data checked by people.
Better data from what you have
Deduplication, filtering, rebalancing, relabeling and decontamination: we turn a noisy corpus into a set you can train on with confidence.
Tests your model hasn't seen
Held-out benchmarks and rubric-scored eval sets that measure the capability you care about, not just leaderboard numbers.
Where we go deep.
Post-training
SFT, preference and reasoning data that shapes how a model behaves, not just what it knows.
- Expert-written instructions and responses
- Pairwise preferences with rationales
- Verified multi-step reasoning traces
Evals & benchmarks
Private, contamination-checked test sets built around your product's real failure modes.
- Rubrics and grader calibration
- Adversarial and long-tail cases
- Versioned splits that never leak
Vision & multimodal
Image, video and depth annotation for models that need to see the physical world.
- Detection, segmentation, density maps
- Video temporal grounding
- Image–text and video–text pairs
From a fuzzy goal to a versioned dataset.
- Week 0Scope
We start from the model behavior you want, then work backward to a data spec, schema and acceptance criteria.
- PilotPrototype
A small pilot batch to check the spec against your training loop before we scale anything.
- BuildProduce
Sourcing, creation and annotation by vetted contributors, with automated checks running throughout.
- QAVerify
Layered review, agreement scoring, and model-assisted audits to find errors before your model does.
- ShipDeliver
Versioned splits, a full dataset card, and provenance for every row, in the format your pipeline expects.
Every dataset ships with its receipts.
- Provenance. Where every example came from, and who touched it.
- Rights. Licensed or consented sources only, documented per source.
- Privacy. PII detection and scrubbing before anything leaves our pipeline.
- Quality. Measured agreement and error rates, reported rather than assumed.
- Hygiene. Deduplication and decontamination against public benchmarks.

Creative Data Lab is founded by Srijan Bhushan, a data engineer who has built production data pipelines and hands-on AI projects, from local LLMs to video and vision models.
