What BUNBU does

BUNBU COMPANY LIMITED is a Vietnam-based offshore software development company founded on December 15, 2017, in Hanoi, operating as a controlled subsidiary within Japan's Appirits Group (TSE: 4174). The company provides three core service lines: lab-type development (dedicated engineering teams assigned to clients under a long-term agile partnership model), contract-based fixed-price development for scope-controlled deliverables, and AI/ML development encompassing generative AI implementation (including GPT-4-based solutions), demand forecasting, image recognition, and anomaly detection. Its primary target market is Japanese enterprises pursuing digital transformation, with all client-facing communication conducted in Japanese through Bridge Software Engineers (BrSE) and coordinated with the parent company's Japan-based teams.

BUNBU's technical stack spans Ruby, JavaScript, Python, PHP, Swift, Kotlin, Flutter, AWS, MySQL, and DynamoDB, supporting web, mobile (iOS/Android), and PWA development. The company has delivered notable client-facing platforms across diverse verticals, including KiZUKAI (AI-driven customer data analytics and churn prediction SaaS), Zaimo.ai (AI-powered business planning and financial management SaaS), Kindy (nursery management PWA), fufu+ (e-commerce for salon-exclusive haircare products), LilyHome (service apartment platform), Cloud Beauty (beauty industry platform), and Teg (B2B wholesale EC platform for salons). These projects demonstrate full-stack development capability, AI integration depth, and domain-specific SaaS delivery.

The revenue model combines subscription/recurring revenue from dedicated team (ODC) contracts, one-time project fees from fixed-price engagements, and professional services fees from AI/data analysis consulting. Customer acquisition is sales-led, driven by inbound website inquiries, free 30-minute consultations, content marketing through the BUNBU blog, and referral leverage from Appirits Group's Japanese customer network. The company also operates a distinctive "Free PoC – Pay for MVP" engagement model, providing a 7-day free proof-of-concept with the option to proceed to MVP development at 30-50% below market rates.
