OfferBox

What OfferBox does

OfferBox, operated by i-plug, Inc. (株式会社i-plug, headquartered in Osaka, Japan, founded 2012), is a reverse-recruitment (逆求人型) online platform for new-graduate hiring in Japan. The core product inverts the traditional Japanese job-hunting flow: students register, build a self-promotion profile including text, photos, videos, and aptitude results, and qualified companies proactively send interview and internship offers to students whose profiles match their hiring criteria, rather than students applying to companies. The platform has accumulated roughly 250,000 registered students across the 2027 graduating cohort and over 22,767 cumulative corporate accounts, with 69% of Tokyo Stock Exchange Prime-listed companies reportedly holding an OfferBox account.

The technology stack centers on a web and mobile (iOS/Android) self-service marketplace with profile matching, direct messaging, and an integrated proprietary psychometric module called AnalyzeU+, which scores students on 28 attributes across 'social basic abilities' and 'next-generation leadership abilities' using data accumulated from approximately 1 million diagnoses, and segments users into 8 animal-personality typologies. Supporting products include OfferBoxPLUS (human career-advisor service), 人事ZINE (HR professional web magazine), 就活ボイス and OfferBox Story (student success content), and an enterprise API integration via Thinkings Inc. The platform holds an employment placement business license under Japan's Employment Security Act (license number 27-ユ-301841) and ISMS certification.

The business model is two-sided and primarily transaction-based. Students use the service for free. Corporations pay placement fees (documented at 100% of first-year annual salary for indefinite-term placements, with a refund if the candidate declines before start date). Distribution combines a self-service product-led motion for students with a direct enterprise sales team and a tiered certified channel-partner network (Platinum/Gold/Silver) of recruiting agencies and HR consultancies for corporate accounts. i-plug generates revenue from per-placement fees on the core platform plus premium advisor services from OfferBoxPLUS, while operating within the regulated Japanese recruitment-services framework.

Direct peers

• Wantedly: Japanese reverse-recruitment / talent marketplace platform connecting candidates with companies through profile-based matching. Most directly comparable to OfferBox in business model (employers reach out to candidates), with a slightly broader scope across experience levels.
• キミスカ (Kimisuka): Reverse-recruitment platform focused on new graduates in Japan, with offer-based matching similar to OfferBox. Operates as a direct category competitor targeting the same student and corporate segments.
• dodaキャンパス (Recruit): Recruit's reverse-recruitment service for new graduates using an offer-based model. Directly competes with OfferBox in the same Japanese new-graduate funnel, backed by Recruit's larger database and marketing scale.
• キャリアチケット (Career Ticket): New-graduate recruitment service combining offer-based matching with career advisor support — closely mirroring OfferBox's OfferBoxPLUS layer. Direct competitor in the assisted new-grad recruiting segment.

Broad incumbents

• マイナビ (Mynavi): Major Japanese job portal and HR services provider competing with OfferBox in new-graduate recruiting as part of a broader portfolio including mid-career placement, media and events.
• リクナビ (Rikunabi) — Recruit: Japan's largest new-graduate job-search portal operated by Recruit. Competes broadly in the same market but via a traditional application-based (rather than offer-based) flow, and across a much wider portfolio of HR services.
• Indeed Japan: Global job-search aggregator with a Japanese operation covering new-graduate and experienced-hire listings. Competes indirectly for corporate recruiting budgets but lacks OfferBox's reverse-offer model.
• LinkedIn (Japan): Global professional network increasingly used for early-career and new-graduate recruiting in Japan. A broad incumbent whose profile-based matching overlaps loosely with OfferBox's core value proposition.

Emerging players

• Handshake: US college-student recruiting platform connecting students and employers via profile-based matching. Conceptually similar to OfferBox's reverse-recruitment model but at much larger scale in the US market.

Regional players

• JobTeaser: European graduate recruitment platform integrated with universities, focused on early-career employer branding and job matching. Comparable business model to OfferBox but operating in EMEA rather than Japan.
