Public ATS and Steam APIs Offer Untapped B2B Lead Sources Without Paid Tools

A developer has highlighted two publicly accessible, keyless data sources that can generate B2B leads outside the usual paid databases. Applicant tracking systems like Greenhouse and Lever expose open job postings via public JSON APIs, letting sales teams identify companies actively hiring in specific departments as a buying signal. Steam's store API can similarly be used to discover game studios by genre, pulling developer names, websites, and review counts without authentication. Both approaches rely on data companies publish themselves, though coverage gaps exist — not all firms use these ATS platforms, and smaller indie studios often lack complete contact details. The developer has packaged both methods as pay-per-use scrapers on Apify, with the first results of each run available free for preview.
