DIPROTECH

DIPROTECH is a Tokyo-headquartered development shop with engineering based in Da Nang, Vietnam. The company builds custom AI systems, web platforms, and mobile apps for Japanese clients. It operates two offices: a sales and consultation base in central Tokyo (Chiyoda Ward) and development operations in Da Nang.

The firm positions itself as a full-stack partner, handling everything from business problem analysis and consulting through to deployment and ongoing maintenance. It does not use subcontractors—development happens in-house, which the company argues simplifies handoff after launch and keeps team continuity high.

Services and capabilities

DIPROTECH structures its work around three branded service lines: AI-PRO, WEB-PRO, and APP-PRO.

Under AI-PRO, the company offers custom machine learning and deep learning projects. Specific applications listed include AI-OCR, predictive models, natural language processing, image recognition, audio transcription, and data scraping. The site mentions work with machine learning and deep learning frameworks but does not name particular model architectures or vendors.

WEB-PRO covers everything from simple site builds to complex business systems. The firm has built reservation systems (hotels, restaurants, studios), marketplaces and matching platforms (dating, job boards, gig work), e-commerce sites in apparel, beauty, and furniture verticals, learning management systems, sales and CRM systems, and portal sites. It supports WordPress, Movable Type, EC-CUBE, Bubble, and Shopify, as well as custom-built systems. The company emphasizes "odermeido" (custom-fit) solutions that can't be solved with off-the-shelf packages.

APP-PRO builds iOS, Android, LINE Mini Apps, and hybrid applications. Categories span reservation apps (travel, salons, dining), EC apps (supplements, fashion, groceries), live-streaming (webinars, fan clubs, music), health and fitness tracking, and business operations (timekeeping, sales, inventory, production management). UI and UX design is positioned as a core strength—the company highlights professional designers and a focus on both aesthetics and usability.

Both WEB-PRO and APP-PRO offerings run on two engagement models. Lab-model work assigns a dedicated team for a fixed period with the flexibility to scale team size and adjust requirements mid-project. Fixed-price projects define scope, timeline, and deliverables upfront; DIPROTECH commits to delivery by a set date. The company also handles migration and feature expansion of existing systems.

Maintenance and monitoring services are offered post-launch: server monitoring, technical support, and incident recovery.

Notable work

Two named clients appear in testimonials. Sheestar (シースター株式会社) praised the speed, politeness, and design quality of an app DIPROTECH built for them, noting features were delivered on schedule and the team was trustworthy for repeat engagements. Palplat (palplat株式会社) highlighted DIPROTECH's proactive suggestions beyond the stated requirements, careful upfront documentation, and speed of communication—describing offshore engagement from DIPROTECH as "standing out" compared to other vendors. Neither testimonial provides quantified business outcomes, but both stress responsiveness and proposal quality over reactive development.

How they work

DIPROTECH structures engagements around three stages: planning (business analysis, requirements definition, consulting), execution (design, development), and support (maintenance, technical help, incident recovery). An IT consultant handles initial scoping even when requirements are still nebulous; the firm documents requirements in plain language rather than technical jargon. Estimates are finalized after this scoping phase.

The company handles localization for Japanese clients—contact is in Tokyo during Japanese business hours, with development happening in Vietnam. Specific SLAs, communication cadence, or pricing models are not detailed in the source.

Team and credentials

DIPROTECH has not disclosed total team size or headcount breakdown. The company mentions "numerous professionals" on staff with experience in machine learning and deep learning, but provides no formal team metrics. No ISO, SOC 2, or other security certifications are mentioned. No partner badges (AWS, Google Cloud, Microsoft Azure) are claimed, though the site lists these platforms in its tech stack. The company is not listed in visible partnership programs.

The firm was incorporated as 株式会社DIPRO with ¥5 million in capital. A separate legal entity, "DIPROTECH," appears to be the brand used externally. Founding year is not stated.
