About OpenTrain AI

OpenTrain AI is a talent marketplace and managed service that connects AI teams and employers with pre-vetted AI Trainers, data labelers/annotators, and AI data vendors. The company positions itself as the “talent layer, not the tool,” enabling customers to hire specialists who work directly inside the customer’s existing annotation, evaluation, or internal tooling rather than requiring migration to a proprietary platform. For self-serve hiring, teams can post a job once and receive curated, ranked shortlists based on AI matching, resume screening, project-specific skill tests, and a live AI interview process. Customers can then hire, manage team communication, share instructions and training materials, track progress, and pay globally through a single workspace with transparent fees. For larger or complex programs, OpenTrain offers a Managed Service that recruits, onboards, trains, manages day-to-day operations, and performs QA while operating inside the customer’s tools and workflows. In addition, OpenTrain provides a vendor marketplace for sourcing pre-vetted data labeling and LLM service providers via a single RFP process with standardized proposals, optional escrow payments, and anonymous sourcing until the customer chooses to reveal their identity.
