Paiza

What Paiza does

Paiza株式会社 is a Tokyo-based, privately held Japanese company founded in 2012 (originally as ギノ株式会社) that operates a multi-sided platform for IT engineers combining online programming skill assessment, structured learning content, and recruitment services. The company's flagship technology is the patent-protected paizaスキルチェック (Patent No. 5649148), a 6-tier (S–E) online coding evaluation system that executes real code submissions across more than 28 programming languages and has accumulated 35.9 million examinations as of March 2026. The platform serves three primary customer segments: individual IT engineers and programming learners (subscription at 1,490 yen/month, supplemented by free tiers and a free "school pass" for educational institutions), Japanese companies recruiting IT talent (5,000+ corporate accounts as of March 2026), and educational institutions (679 schools enrolled in the free pass program, with paid content distribution through partners such as Benesse).

The technology stack centers on a cloud-based online code execution environment (paiza.IO / PaizaCloud) and a video-based learning management system, with 2025–2026 product extensions that include an SQLスキルチェック for non-engineer business users and a Vibe Coding curriculum series that integrates Claude Code, OpenAI Codex, and MCP servers for AI-assisted development learning. Revenue is generated through five distinct streams: B2C subscription (paizaラーニンング), B2B recruitment services (paiza転職/paiza新卒), freelance matching (paizaフリーランス, launched May 2024), B2B licensing to partners such as Benesse's Shinken Zemi course, and paid IT-engineer career-change support (paiza.EN:TRY).

Paiza distributes through a hybrid go-to-market: self-serve web platform for individuals, direct enterprise sales for recruitment clients, a freemium channel to schools, and co-marketing partnerships. The company employs 51–100 people, is headquartered in Minato-ku, Tokyo, and is currently led by President/CEO 舘康人 (appointed November 28, 2025), with founder 片山良平 transitioning to Chairman. The business is debt-free by appearance (no disclosed funding rounds, 140,000 thousand yen registered capital) and holds ISO/IEC 27001:2022 certification, paid job-placement and worker-dispatch licenses, and brand recognition reinforced by ASPIC Cloud Award 2023 and a #1 ranking in an IT-engineer survey of career-development job-hunting services.

Scale indicators8 records

Recent moves7 records

Expansion highlights7 records

Broad incumbents

• Coursera: Global online learning platform partnering with universities and enterprises. Comparable on the corporate training and credentialing side of paiza's business, particularly for upskilling existing engineers.
• Udemy: Global marketplace for online technical courses with significant Japanese user base. Competes for the same individual learner wallet as paizaラーニング, especially in higher-priced, self-paced programming content.
• Bizreach: Largest Japanese platform for mid-career and executive recruitment, owned by Visional. Operates a much broader HR business but is the dominant incumbent in the same Japanese talent market where paiza's recruitment business competes.
• Recruit Holdings: Japan's largest HR/education conglomerate, operating Rikunabi (new-grad hiring), Indeed Japan, and Study Sapuri. Encompasses the same hiring-and-learning categories as paiza at vastly greater scale, and is the new CEO's former employer.

Emerging players

• AtCoder: Japan's largest competitive programming platform with a global following. Adjacent to paiza's programming-games franchise and a potential talent-pool upstream of paiza recruitment, though it does not directly operate a hiring marketplace.
• HackerRank: Global developer skill assessment and hiring platform. The closest international analog to paizaスキルチェック, serving the same corporate need for objective coding skill verification that paiza's patented system addresses in Japan.

Direct peers

• Progate: Leading Japanese online programming education service with a subscription model and tiered curriculum. Most direct peer to paizaラーニング for individual learner subscription revenue, and increasingly a competitor for entry-level education content.
• LAPRAS: Japanese developer-portfolio and skill-based matching platform that screens engineers using public code activity (GitHub, Qiita, blogs). Directly comparable to paiza's skill-check + recruitment thesis, with a similar dual-sided marketplace for engineers and employers.
• Qiita Jobs: Recruitment vertical of Qiita, the dominant Japanese programming knowledge-sharing community. Competes with paiza for both candidate mindshare (developer community traffic) and corporate recruitment spend, especially for mid- and senior-level engineers.
• Wantedly: Japanese tech-focused recruitment and company-information platform. Closest direct competitor to paiza転職 in the Japanese IT engineer hiring market, with overlapping B2B subscription model and similar target user base of working engineers.
