株式会社ハイヤールー

株式会社ハイヤールー operates HireRoo, a Japanese-language organizational development platform that quantifies engineers' ability to work with AI coding tools (referred to as "AI協働力", or AI collaboration capability) and applies that measure across hiring, internal evaluation and skill development. The platform is built on a proprietary skills framework called the Software Engineering Index (SEI), described as covering five domains and 460 rubric-scored evaluation criteria, constructed with reference to academic papers, advisors and other sources.

The product line consists of three modules plus an advisory option. Skill Interview is a coding assessment for hiring in which candidates work in a pre-configured integrated environment with Claude Code, Codex and GitHub Copilot installed on deliberately abstract tasks; the AI-usage and problem-solving process can be replayed afterwards, and reports break down scores by SEI domain. Skill Assessment visualizes both the quantity of AI usage (token volume and cost across tools) and its quality (SEI scoring) for existing engineering team members, ranking members and identifying high performers to support AI investment ROI analysis. Skill Development, listed as coming soon, is intended to distribute and track individually optimized learning plans generated from assessment results, with re-testing and feedback loops. An optional professional service, "CTO as a Service", provides a dedicated team covering hiring-process design, internal AI assessments and training plan design.

Operationally, the platform is positioned so that HR staff can run it without in-house engineers, since question delivery, scoring and report generation are automated; the company states assessments can be issued the same day a contract starts, integrations exist with major ATS products and Slack notifications, and a demo environment with a free trial is available.

Business model

B2B SaaS assessment platform sold to employers, with pricing published on the company's site, an optional "CTO as a Service" professional-services engagement layered on top, and free trials or phased rollouts available on request.

Traction

As of July 2026 the company reports 317 client companies and 1,165,360 evaluations underpinning its index. Case studies report a 2.3x increase in resume pass-through rate and 3.2x increase in offer acceptance rate at one business-platform customer, reduced engineering-manager screening workload at an entertainment customer, and reduced mismatches at a food-sector customer. For the CTO as a Service option the company cites 1.6x candidate pipeline size, a 37% reduction in spend on AI promotion, and a 20% improvement in AI utilization rate within development processes.
