Training data, labeled like your model depends on it.
Because it does. VB-Optic Labs delivers pixel-perfect, expert-reviewed annotation across every modality — the same rigor our own vision models are trained on, now available to your teams.
Every data type. One standard.
Image to LiDAR to language to human preference — one vendor, one quality bar, one integration.
Image
Pixel-perfect labels for detection, segmentation and classification at scale.
Video
Frame-accurate tracking and event labeling with temporal consistency.
3D / LiDAR
Cuboids and sensor-fusion labels for autonomy and robotics stacks.
Text & NLP
Entity, intent and relationship labels across 40+ languages.
Audio & Speech
Transcription, diarization and acoustic event tagging in Indian and global languages.
GenAI / LLM
Human feedback that turns raw models into aligned, safe products.

follow-the-sun delivery
Quality is a process, not a promise.
Every label is measured against a gold-standard set you can audit in real time. If accuracy dips below your SLA, work stops — not ships.
Scope & gold set
We co-author the labeling guidelines with you and build a gold-standard benchmark set before a single production label is drawn.
Trained workforce
Vetted, domain-trained annotators — managed in secure facilities or on-prem — are onboarded against your guidelines with qualification tests.
Multi-pass QA
Every task runs through consensus labeling, reviewer passes and automated checks. Disagreements escalate to expert adjudication.
Gold-standard audit
Continuous sampling against the gold set keeps measured accuracy above your SLA — with a live quality dashboard you can watch.
Deliver & iterate
Labels ship in your format via API or secure export, with a full audit trail. Model-in-the-loop feedback tightens each subsequent batch.
Trusted across frontier teams
Your data never leaks
Managed secure facilities or fully on-prem workforces, granular access controls, PII redaction and a complete audit trail on every task. Sovereign deployments for government-grade data.
