People Search Bench

Open benchmark for evaluating AI-powered people search agents and platforms

Visit github.com ↗

People Search Bench is an open evaluation framework and dataset designed to test how accurately AI agents find real people from natural language queries. Rather than relying on subjective LLM-as-a-judge scores, it decomposes queries into verifiable criteria and validates candidates against live web sources across 119 diverse tasks.

What it's for

  • Evaluate the accuracy and coverage of AI agents in finding professional contacts and leads
  • Benchmark search engines and agent tools across recruiting, B2B prospecting, and expert discovery
  • Stress-test retrieval workflows on multi-constraint people-search queries

Features

  • 119 benchmark queries spanning four categories: Recruiting, B2B Prospecting, Expert/Deterministic, and Influencer discovery
  • Multilingual coverage featuring queries in English, Spanish, Portuguese, and Dutch
  • Criteria-grounded scoring pipeline using Tavily web search to verify returned candidates against factual requirements
  • Three standardized metrics: Relevance Precision (padded nDCG@10), Effective Coverage, and Information Utility
  • Head-to-head comparisons across tools like Lessie, Exa, Juicebox, and Claude Code
