Services / Headhunt.AI Technology
Headhunt.AI scores, ranks, and personally messages candidates at scale. Built since 2018, trained on real Japan placement data, with keigo, honne/tatemae, and Japanese compensation norms designed in from day one. Available to external customers as a standalone SaaS product at headhunt.ai.
Capabilities
Four capabilities that compound. Each one is useful on its own. Together, they replace what took a recruiter days with what takes Headhunt.AI seconds.
Upload a JD. In under 30 seconds, Headhunt.AI scores all 4M+ candidates against the role, producing a ranked list with ESAI Scores from 0 to 100. What took a recruiter a week now takes less time than making coffee.
Every candidate gets a 0-100 ESAI Score on every role. The score combines skill match, experience alignment, culture fit, career trajectory, and subtler signals like industry mobility patterns. Recruiters can focus their time where it matters.
For every candidate, Headhunt.AI generates a unique scout message referencing their actual background, current company, skills, and the specific hook most likely to resonate. No templates. No copy-paste. Response rates run 40% above Japan industry average.
Every scout message, candidate summary, and output can be produced in native business Japanese with natural keigo, or in polished English, or both simultaneously. Most AI tools treat Japanese as a translation target. Ours treats it as a primary language.
What makes it different
Most recruiting AI tools launched in 2023-2025 are built on general-purpose LLMs, with Japan added as a translation layer. Headhunt.AI was designed in Tokyo for Japan from day one, and has been learning from real placements since 2018.
Our scoring model learns from real Japan placements since 2018, not synthetic data, not off-the-shelf LLMs. Every placement AgentRPO closes feeds back to improve the system.
Every candidate-role match is evaluated across 3,000+ signals, skills, experience, career trajectory, industry mobility patterns, compensation history. A single ESAI Score (0-100) summarizes the fit. Recruiters focus time where it matters.
Designed in Tokyo for Japan. Keigo, industry-specific culture fit, honne-vs-tatemae signaling, and compensation norms are native capabilities, not translated from an English-first system.
AgentRPO uses Headhunt.AI every day in production. Every search, every scout, every placement becomes feedback that improves the system. You benefit from a tool that's running at real scale, not a demo.
