Data quality and method

What is measured, how, and where it is weak. Refreshed with every build; this page is the reference for the numbers on the site, in the emails and in the exports.

Failed today: instabase. A failed source keeps its last good postings for that build.

Sources

Every posting comes from the company's own careers system through the public job-board APIs of Greenhouse, Lever and Ashby, four times a day. Nothing is scraped from LinkedIn or aggregators, and nothing is self-reported. A posting counts as closed when it disappears from its company's feed; the index cannot tell filled from withdrawn.

Definitions

• New roles. Postings whose posting date falls in the window; where a feed has no date, the day the index first saw it.
• Leadership seats. Titles containing Head of, Director, VP, GM or C-level, excluding client-facing and assistant titles (account director, chief of staff, field CTO and similar). One seat posted in several cities is one row.
• Velocity. New roles in 7 days against the company's prior four-week weekly average; "accelerating" needs at least 5 new roles and twice the average.
• Expansions and new functions. A first posting in a region or function not present in the company's current or tracked postings; companies with 10+ live roles only. Until the archive is 90 days old this means "first since tracking began".
• Time to fill. Median days a closed posting was open, per company, over the last 90 days, ignoring postings older than a year.
• Salary. Annual base ranges parsed from the compensation field or description; 8,000 informative USD ranges (top under 3x the bottom). On-target-earnings ranges (493) are flagged OTE and excluded from base medians. Level is inferred from the title.
• Functions. Assigned from title and department by rules with tests; expect a few percent of roles in the wrong function.
• Skills. Word-boundary matches against 69 tool and skill names, after removing each company's boilerplate paragraphs.

Known limits

• Companies not on Greenhouse, Lever or Ashby are not tracked; the list is in Companies.
• Posting dates on some feeds are the last edit, not the first publication.
• Ranges are as posted; a company-wide placeholder band shows up as one.
• History starts on the first tracked day, so week-over-week and 90-day signals mature over the first quarter.
