Build human-powered multimodal AI datasets

Martello provides end-to-end data annotation and collection services designed for modern AI development. Our delivery model combines experienced human execution with structured orchestration to ensure quality, traceability, and repeatability across every dataset we deliver.

Clients choose Martello not just for results, but for confidence in how those results are produced.

About Martello

Martello is a data annotation and collection services provider built for teams that require more than outsourced labor.

We operate using a proprietary orchestration platform that governs how work is planned, executed, reviewed, and delivered. This platform-driven operating model enables stronger quality control, clearer accountability, and better outcomes across complex AI data programs.

Martello bridges the gap between raw human effort and production-grade AI datasets.

Capabilities across the full data lifecycle

Martello delivers managed data services supported by structured workflows, defined quality gates, and clear ownership at every stage.

Multimodal data collection at scale

Martello delivers global data collection programs across all major modalities, including text, images, audio, and video.

Our collection services support:

• Web, mobile, and app-based data capture
• Large files and complex media formats
• Global contributor recruitment and onboarding
• Secure ingestion from existing datasets
• Integration with major cloud storage providers

Collection is executed with the same discipline and controls applied throughout the entire data lifecycle.

Orchestrated human-in-the-loop delivery

Martello's core differentiator is orchestration—the system that governs how human work is executed at scale.

Every engagement follows a structured lifecycle:

Collection → Annotation → Validation → QA → Delivery

DELIVERY

Each stage includes:

• Defined roles and responsibilities
• Clear handoffs and approvals
• Quality thresholds and review logic
• Escalation and resolution paths

This orchestration ensures consistency, reduces rework, and enables datasets to be extended, audited, and reused over time.
