Coverage
Domain-specific taxonomies for every major sport. Our annotators understand the rules, not just the pixels.
Swing biomechanics and high-precision ball flight telemetry.
Formations, routes and contact events, with identity held through helmets and pile-ups.
How We Work
Every engagement starts with understanding your requirements in detail. We don't do one-size-fits-all.
STEP 01 / 05
STEP 01
We understand your use case, data schema requirements, volume, format preferences, and delivery timeline. No templates — every engagement starts from your specific requirements.
STEP 02
We propose a tailored annotation workflow, team structure, and QA framework designed for your specific sport and data type. You review and approve before anything starts.
STEP 03
We deliver a sample dataset so you can validate quality, schema alignment, and accuracy before committing to full production. Zero risk, full visibility.
STEP 04
Our expert team begins full-scale annotation with continuous QA checks, accuracy monitoring, and a dedicated project manager keeping you updated every step.
STEP 05
We grow with your needs. Add new sports, increase volume, refine schemas, or expand scope — your dedicated team scales with you, not against you.

Who We Serve
Your model quality starts with data quality — regardless of which segment you build for.
Your models process thousands of hours of footage weekly. Generic vendors break on player overlap, occlusion, and rapid movement — sports-trained annotators don't.
Bounding boxes won't train a biomechanics model. Your systems need 22-point skeletal precision — annotation depth most vendors cannot deliver.
One frame of annotation error breaks your AR overlay. We deliver frame-perfect event synchronization at the precision live broadcast demands.
Annotation errors corrupt your prediction models and distort your odds engine. Our event pipelines are built for the data fidelity your risk infrastructure requires.
About Us
Train Matricx is a specialist data service agency. We combine deep sporting knowledge with rigorous annotation methodology to produce high-quality, structured sports data that powers AI models, betting systems, media products, and analytics platforms worldwide.
Behind every dataset we deliver is a team of human experts who understand the game — not just the data. Our annotators are former athletes, coaches, statisticians, and passionate sports professionals with years of first-hand experience in their disciplines.
What sets our team apart
Our global team covers live events around the clock, across all time zones — so your data is ready when the final whistle blows.
Every data point is reviewed by annotators who know the sport. We catch what algorithms miss — contested calls, context, nuance.
We deliver in the format your system expects — JSON, CSV, XML, direct database feeds, FTP, or API. No transformation work on your side.
Sports happen everywhere. Our annotators cover events in multiple languages and regional contexts — European leagues, Asian markets, and beyond.
