ISO 27001 data annotation services for AI and ML teams in regulated industries
Bounding boxes, polygons, segmentation masks, keypoints, landmarks, and classification labels for detection, segmentation, and classification models, with human validation on every batch.
Frame-by-frame boxes, masks, keypoints, and identity-consistent object tracks for detection, tracking, and action-recognition models, validated at the sequence level.
3D cuboids, point cloud segmentation, drivable-area labeling, and object tracking for robotics, autonomous mobility, geospatial, and industrial AI programs.
Text-region labeling, document segmentation, handwriting annotation, structured field extraction, plus LLM evaluation with calibrated rubrics and GenAI alignment data.

Build, deploy, and govern production-ready agentic AI workflows
A visual canvas where retrieval, branching, tool calls, human review, and model steps form a visible, testable execution path you can debug and hand off.
Create agents through chat or manual configuration, give them skills, tools, and knowledge, then ship them as apps, embeds, or reusable nodes inside workflows.
Build repeatable ingestion pipelines for documents, sites, and drives, with extraction, cleaning, chunking, indexing, and retrieval testing before you go live.
Install model providers, tools, data sources, and MCP integrations once and reuse approved plugins across every app in the workspace.

The environments frontier AI trains on, and the agents that do the recurring work

Human-validated training data and evaluation services for frontier AI models


SpecialistProvides advanced programmatic frameworks for document parsing and RAG pipelines, but requires coding instead of visual canvases.


Free / Open-sourceAI data infrastructure for building production-grade models
Free / Open-sourceAn open-source automation platform combining visual flows with AI steps, though geared more towards general app integration.
The multimodal data layer for computer vision and physical AI teams

Built for scaling multi-agent workforces and B2B task automation, though less focused on open-source RAG pipelines.

Focuses on visual drag-and-drop orchestration for building chatbots and autonomous agents without writing code.

Provides an all-in-one visual workspace for building custom AI agents and publishing them to messaging platforms.
