Kestrel Metric Lab

Kestrel Metric Lab is a small New York group of four statisticians that carries out the independent bias audits required under New York City's Local Law 144 and prepares the equivalent disparate-impact analyses that employers in Illinois and Colorado are increasingly asked to produce. The lab's founder, Jonah Feldstein, completed a doctorate in statistics before working on hiring analytics at a payroll company; the other members are quantitative researchers who join per engagement. Each audit begins with a data template, a short call to confirm the categories in scope and a signed independence statement, and ends with a public summary and a longer technical memo for the client's counsel. For a single automated employment decision tool with clean historical data, fees stay under five thousand dollars and turnaround is roughly two weeks. Vendors with many customers using the same tool are quoted on a per-tool basis rather than per employer. Kestrel does not provide policy drafting, does not advise on whether a tool is legally in scope, and will not audit tools it helped design. The team works remotely across the Northeast and takes on no more than six audits at a time, so booking a slot two months ahead is usual during the spring reporting season.
