Trusted by innovative tech teams worldwide
The Bridge Between
Human Intelligence & Machine Learning
Data Annotation
Text, image, audio, and video annotation with multi-tier QA pipelines. Our annotators are trained domain specialists — not crowdsourced generalists.
3D LiDAR Annotation
High-precision point cloud labeling and object tracking to fuel autonomous vehicles, robotics, and spatial AI. We turn complex 3D sensor data into flawless, model-ready training pipelines.
Data Validation
Independent QA layer to verify existing datasets. Catch errors, reduce model hallucinations, and certify dataset quality before training runs.
What Our Partners Say
Frequently Asked Questions
We use a multi-tier QA pipeline: annotators, senior reviewers, and automated consistency checks. Every dataset ships with a quality certificate and a disagreement analysis report.
We operate under SOC 2-aligned controls and are on the ISO 27001 certification track. All annotators sign strict NDAs, work in access-controlled environments, and client data is never retained beyond project scope.
Text (NLP, NER, sentiment, classification), images (bounding boxes, segmentation, keypoints), audio (transcription, speaker diarization), video (temporal annotation), and RLHF preference pairs for LLM alignment.
Discovery call to kickoff typically takes 5–7 business days. We can deploy a trained annotator team within 30 days of project confirmation for most project types.
Yes. We annotate point cloud data for autonomous vehicles, robotics, and spatial AI — including 3D bounding boxes, semantic segmentation, and multi-frame object tracking. Our teams are trained specifically on LiDAR sensor data and sensor fusion workflows.

Custom Workforce Build
We recruit, vet, and domain-train annotators matched to your specific industry or technical stack.
Weekly Feedback Loops
Structured reporting that converts model failure modes into annotator training modules — closing the quality loop continuously.
Your Data Is
Safe With Us
SOC 2 Aligned Controls
We operate under security policies mapped to SOC 2 Type II requirements — covering availability, confidentiality, and processing integrity.
Strict NDA & Access Control
All annotators sign legally binding NDAs. Data access is role-based and project-scoped — no one sees data outside their assignment.
Zero Data Retention Policy
Client data is not retained beyond project completion. Secure deletion is confirmed in writing at project close.

The CoreBridge
Approach
We've built a proprietary system that makes the "human" in Human-in-the-Loop a competitive advantage, not a bottleneck.
Discovery & Scoping
We start with a deep project brief — understanding your model architecture, failure modes, and quality requirements. We define accuracy thresholds, turnaround benchmarks, and security protocols before a single label is applied.
Team Recruitment & Domain Training
We recruit annotators from Kenya's growing tech talent pool — prioritizing youth and underrepresented communities. Each project team receives a custom training curriculum built from your model's specific requirements and past failure modes.
Multi-Tier QA Pipeline
Every task passes through annotator → senior reviewer → automated consistency check. Disagreements trigger mandatory consensus sessions. Our QA system surfaces systematic annotation errors before they compound into dataset-level problems.
Weekly Feedback Loop
Our proprietary reporting cadence converts your model's technical failure signals into structured annotator training modules. What your model gets wrong on Monday becomes a training session by Thursday — closing the loop faster than any other vendor.
Delivery & Certification
Datasets are delivered 20% faster than industry average via our optimized project management workflow. Every deliverable includes a quality certificate, disagreement analysis, and annotator confidence distribution report.
What CoreBridge Stands For
SLA-backed accuracy commitments. If we miss the target, you don't pay for rework.
We function as an extension of your ML team — not a vendor. Your project manager has direct access to your lead engineer.
We refuse to treat annotation as a commodity. Every label is a training signal. We treat it that way.
Built in Kenya.
Built for the World.
CoreBridge AI was born from a simple conviction: that Kenya's growing pool of educated, English-fluent, technically capable youth deserved a place inside the global AI economy — not on the margins of it.
The global AI industry consumes billions of human-labeled data points. Most annotation work is outsourced to crowdsourcing platforms where quality is inconsistent and workers are invisible. We built a different model.
CoreBridge operates as a high-accountability partnership firm. Our annotators are named professionals, not anonymous crowd workers. They receive structured training, fair compensation, and a career pathway in AI. In return, our clients receive something rare: a data partner they can actually trust with their model's development.
We are intentionally Kenyan-built and globally-minded. We're proud to be creating AI-ready digital careers in Nairobi, and we're equally proud to deliver datasets that power frontier AI products worldwide.
