Project identified as ContactOut, a prominent B2B recruiting and data intelligence tool, despite the submission name 'WhisperKeeper' (likely a clerical error). External verification confirms substantial scale with ~$15M+ estimated revenue and ~1.4M users (76% of Fortune 500). While the submission quality is exceptionally poor (lazy answers, name mismatch, empty fields), the underlying project demonstrates high real-world utility and massive verifiable traction, placing it in the top tier of established technology businesses.
