AI job-search automation that applies to matching roles for you
Saved loops of job titles, locations and filters are matched against new postings, which LoopCV then submits on your behalf or queues for one-click approval.
Finds recruiter email addresses, sends personalised messages built from your own or prebuilt templates, and reports opens and replies.
Audits your resume for format and keyword issues, then helps you produce tailored variants you can compare against each other.
Keeps every application, its status and follow-up history in one dashboard instead of scattered spreadsheets.

Hire tested AI trainers and data labelers for RLHF, evaluation, and annotation
Post a project and receive a shortlist drawn from a network of more than 711,000 people across 240+ countries, available in 120+ languages.
Applicants pass automated interviews and domain skill assessments, and managed programs add live proctored testing, so candidates are matched on demonstrated ability rather than self-reported skills.
Hire managers can add experts straight into Label Studio, CVAT, Labelbox, Argilla, or another tool they already run, avoiding data migration.
Beyond standard labeling, the network covers RLHF preference ranking, DPO pair generation, reasoning verification, adversarial red teaming, and human benchmarking.
