One application for practicing three types of selection examinations — with automatic scoring and comprehensive review, so prospective students are ready for the hospitality school entrance exam.
Pengacara-ku is one pattern. A similar implementation can be built for your organization's specific knowledge domain.
—Corporate contracts and standard clauses
—Internal regulations and compliance policies
—Claim documents and insurance claim documentation
—Operational knowledge bases and team workflows
Every Pilot Build engagement is structured as a contract with measurable deliverables — a production-grade AI agent with observability, audit trail, and fail-safe mechanisms.
Premium websites, managed cloud & hosting, web apps & SaaS, business domain & email, payment integration, and AI customer experience — built and operated end-to-end by WTB. The same service line that runs our own products in production.
If your organization requires a similar implementation for a different domain, enter through the Engagement Ladder. Begin with the Diagnostic Workshop to map opportunities, proceed to a Pilot Build to develop a production agent, and transition to a Managed Retainer for ongoing operations.
