Methodology

How we decide which companies to list, what counts as a fact versus a claim, how we keep data fresh, and what we will and won't do for a listing.

Inclusion criteria

A company is eligible for listing if it operates a data annotation / labeling / RLHF service, has a public web presence we can link to, and is currently operational.

Data sources

Company websites and careers pages, public news coverage, job boards, worker-forum signals, direct outreach, and worker-submitted reviews shown on each profile.

Refresh cadence

Hiring status is re-checked opportunistically. Descriptions and specialties are audited less often and usually only when a company materially shifts its offering. Last-verified date is shown on every profile.

Disclosure

No pay-to-rank. Sponsorships are clearly labeled and don't affect organic order. Affiliate links (where they exist) are disclosed. Most job listings are scraped or linked from the company's own careers page.
