Data infrastructure for frontier AI

The best data in the world is locked inside people's heads.

A surgeon knows things no textbook contains. A quant sees patterns no paper describes. That knowledge is the highest-value training signal on earth — and almost none of it has ever been written down. We get it out, and we make models learn it.

Our position

Most data companies collect. They find what already exists in a written form, clean it up, and hand it over.

But the knowledge that actually separates a good model from a great one was never written down. It lives in the judgment of people who've spent fifteen years getting good at something — and it doesn't arrive in a format any model can learn from.

So we don't collect. We translate.

We find the practitioners, sit with them, and build the operational machinery that turns what they know into what your model needs. That's a harder problem than annotation. It's also the only one worth solving.

Data products

Three verticals, organized by what the model learns.

Not by our internal org chart. AI teams think in training objectives, so that's how we've built the menu.

01
Expert Skills Data CORE

Tacit knowledge, made model-ready.

We source from practicing professionals — people with real credentials and real hours — and run structured elicitation to surface the reasoning they can't easily articulate. Then we translate it into training data your researchers can actually use.

  • 30+ professional domains
  • Finance, medicine, law, engineering
  • Human-verified, context-rich output
Best for: reasoning models, SFT, RLHF from domain experts
02
World Model Data

Physical world understanding at scale.

Models that act in the world need to know how the world behaves — objects, physics, space, causality. We build multi-view, temporally-grounded datasets for teams training embodied and world-model architectures.

  • 3D spatial & temporal annotation
  • Physics & causality grounding
  • Indoor / outdoor / industrial scenes
  • Robotics & autonomous systems
Best for: embodied AI, sim-to-real, world models
03
Multimodal Data

Production-grade video & image datasets.

Built by film and TV professionals — directors, cinematographers, editors — who understand what quality means before a model ever sees the frame. Generic vendors can't replicate this, because they don't have the people.

  • Film & TV professional talent
  • Video, image, audio-visual
  • Style-consistent generation sets
  • Fast turnaround at volume
Best for: image/video gen, MLLM fine-tuning, perception

Why FlowData

The gap between knowing and learnable.

Expertise doesn't arrive in a format a model can learn from. Closing that gap is the entire job.
Experts, not crowdworkers
We source from practicing professionals with verifiable credentials. When the person doing the work is the expert, the quality ceiling is a different number entirely.
Dual US–China market depth
Bay Area operations, deep China-side execution capacity. Few teams can run both sides properly — fewer still can do it fast.
Translation, not annotation
Anyone can label. The hard part is the ops machinery that turns unstructured human judgment into structured, verifiable signal. That's what we built.
