The multimodal data layer for computer vision and physical AI teams
Native video, image, LiDAR, audio, text, and sensor-fusion labeling in one workflow, with label lineage and quality controls built for production scale.
Use embedding-based search and model-in-the-loop curation to surface rare edge cases and close distribution gaps before they hurt model performance.
Orchestrate RLHF, rubric-based evaluation, and pairwise comparison for models in production, then route failures back into training.
Access vetted domain experts for annotation and training-ready data collection, fully integrated with the Encord platform.

Full-lifecycle RFP intelligence with deterministic accuracy and grounded AI
Pull opportunities from SAM.gov, eBuy, Find a Tender, and other sources, then score contract fit and run AI win-theme and past-performance analysis.
A rules-based engine shreds requirements, builds compliance matrices, flags liability and risk language through dictionaries and watchwords, and compares versions with 100% repeatable, audit-ready results.
A Prompt Library and approved Collections give teams a running start on competitive intel, win themes, and past performance, with every answer grounded in approved content and cited to source.
Customizable Kanban stages, tasks, reviewers, and comments keep proposal work moving from initiation through red team to submission on one source of truth.
