Litmus on the record

What they shipped

  • From its YC profile: Litmus is building the most accurate framework for evaluating and benchmarking human capability, starting with software. AI will compound small differences in human capability into increasingly large differences in what people can accomplish, while making existing static benchmarks obsolete. Software is already there: AI can hill-climb any output-based evaluation, while the ability to direct it is becoming the defining advantage. Litmus applies the same approach we already use for model evals to humans – creating world-like environments, and inspecting trajectory instead of just output. (source)
  • Its own site describes it as: "Litmus generates technical interview pipelines from your repos, tickets, and job descriptions. Get better signal while saving time. Hire people who last." (source)
