AI data infrastructure for building production-grade models
One configurable annotation surface for image, video, text, and audio projects, so multimodal datasets can be labeled without switching tools.
Search, filter, and inspect datasets to find the examples that will most improve a model, then route them into targeted annotation or review queues.
Dashboards for annotation volume, reviewer agreement, and project progress, plus advanced analytics on upper tiers for program-level reporting.
Metered orchestration capacity for running annotation, evaluation, and data-processing workloads, scaled by plan from roughly 1K to 10K compute hours.

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.
