JIITAK Inc.

JIITAK is a Tokyo-based product development and digital transformation firm that works with companies moving from idea to market-ready product. The company operates across three domains—strategy, design, and engineering—and positions itself as a hands-on partner through the full product lifecycle, from concept validation through MVP launch and growth-stage scaling.

The source lists no founding year, employee count, or notable client names. The company describes itself as having a "global development structure," but provides no detail on where teams are located or how large the operation is.

Services and capabilities

JIITAK structures its offering around business phase rather than service type. The 0→1 phase (ソリューションデザイン) covers strategy work: converting rough ideas into structured narratives and building mockups to validate customer problems. The 1→10 phase is MVP development—turning business hypotheses into functional products with minimal feature sets to test solutions quickly. The 10→100 phase tackles product-market fit and growth, involving feature prioritization and ongoing development.

On the design and engineering side, the company explicitly works with Flutter, React, Node.js, iOS, and Android. Project examples show mobile app development (Flutter-native), web applications, and UI/UX design as core capabilities. The source also mentions "eBay出品サポート" (eBay listing support) as a service, though no further detail is given.

Notable work

The website showcases four shipped projects: a health management app built with Flutter and MVP methodology; a social dating app using Flutter; a workplace dining platform called "GoSmart" (web and mobile); and an affiliate/SNS app. None of these projects are tied to named clients or measurable business outcomes. The descriptions focus on product concept rather than results or client success metrics.

How they work

The company emphasizes "end-to-end" (一気通貫) delivery across strategy, design, and engineering phases, positioning itself as an accompanying partner (伴走型) rather than a vendor. Specific engagement terms, pricing models, communication cadence, and team composition are absent from the source. The email contact is info@jiitak.co.jp.

Team and credentials

No founder names, team size, certifications (ISO 27001, SOC 2, etc.), partner status with major platforms, or third-party ratings are disclosed in the source material. The company's blog covers topics like full-stack development, mobile app security analysis, and AI in software development, suggesting technical depth, but this is inferred from content rather than stated capability.
