What Build It does

Build It Inc. (株式会社ビルディット) is a privately held Japanese education-technology company founded in March 2016 and headquartered in Hachioji, Tokyo. Operating with 1–10 employees, the company develops software that applies information technology to education and human resource development, with a stated vision of being an "Edu-Tech Supporter of 100M+ Growth & Challenge." Its core products center on the Stockr platform, delivered in two variants: a consumer reflection/journaling mobile app (stockr.bldt.jp) for students, working professionals, job seekers, and parents, and an enterprise human-resources platform (Stockr Biz, stockr.biz) that uses AI accompaniment to support daily reflection, 1on1 dialogue quality, new-graduate retention, and autonomous growth for corporate HR departments and training organizations. Both variants leverage an AI reflection companion that operates in the text modality to guide vision planning, daily introspection, and accumulation of insights. The underlying technology stack is not publicly documented, and the AI capability is positioned as a feature layer rather than a proprietary model.

Scale indicators3 records

Recent moves7 records

Expansion highlights5 records

Emerging players

• Atama Plus: Atama Plus builds AI-powered personalized tutoring and adaptive learning products for the Japanese education market (initially K-12, expanding to adults). Comparable to Build It as a Japan-based AI-EdTech operator using proprietary AI to drive individualized learning outcomes.
• Mindset AI: Mindset builds an AI-driven personal coaching and reflection companion for workplace and life goals. Closely mirrors Stockr's AI reflection coaching concept for self-development, though it focuses on English-speaking markets and coach augmentation rather than Japanese enterprise HR.

Broad incumbents

• SmartHR: SmartHR is the dominant cloud HR and employee-management platform in Japan, serving tens of thousands of employers. A broad incumbent that Stockr.biz could integrate with or compete against for share-of-wallet inside Japanese corporate HR/L&D stacks.
• Doorkeeper: Doorkeeper is an established cloud-based HR evaluation and employee-management system widely used by Japanese SMBs and mid-market companies. Adjacent competitor for Stockr.biz's enterprise HR/training decision-maker budget and a likely integration partner.

Direct peers

• Reflect.app: Reflect is an AI-powered daily journaling/note-taking app with networked thought features. Directly comparable to Stockr as an AI-augmented reflection tool for individuals, though it operates globally and is positioned more as a PKM tool than a Japanese-market HR/coaching platform.
• Day One Journal: Day One is a widely used personal journaling app with prompts, photos and now AI-assisted entries. Overlaps with Stockr's consumer reflection-habit formation use case; differs by being a global consumer product without an enterprise HR platform twin.
• Journey: Journey is a cross-platform journaling app with end-to-end encryption and AI features. Closely mirrors Stockr's consumer reflection-habit value proposition for students and professionals; serves as a global benchmark for Stockr's consumer-side UX and retention design.
• Schoo (Schoo, Inc.): Schoo is a leading Japanese online live-learning platform for adult professionals and corporate training, with a large video course library. Directly competes with Stockr.biz for Japanese corporate L&D/training-organization budgets and shares Build It's adult self-development audience.

Others

• TechTrain: TechTrain is a Japanese engineering-education and talent-development startup focused on programming education for students and working professionals. Comparable to Build It as a Japan-based education-technology operator targeting student and professional upskilling, with overlap on AI/DX learning content.

Regional players

• Coach United (コーチ・ユナイテッド): Coach United operates a 1-on-1 lesson marketplace in Japan; its former CTO is Build It's current CEO. Comparable as a Japan-based coaching/talent-development platform and a plausible enterprise channel partner for Stockr.biz's training-organization DX offering.
