Sinciate Inc.

Based in Shibuya City, Tokyo, Sinciate Inc. is a small web production company, founded in 2015, working with organisations ranging from listed companies to small and medium-sized businesses across a range of industries. Its stated portfolio covers more than 400 projects for over 250 clients, including corporate sites, service sites, landing pages, recruitment sites and media sites for companies such as GMO TECH, YAO Design International and Taiyo Cable Tech. The agency positions itself as an ongoing "Web strategy team" for clients rather than a one-off vendor, working through direct dialogue with clients who often approach the company without a fixed brief. Services span web consulting, web design/production and web marketing support, delivered as a single point of contact from strategy through execution. Consulting work includes current-site analysis, market and competitor research, persona design, KPI setting and requirements definition, incorporating SEO, advertising, SNS and AI-based measures. Production covers corporate, service, LP, recruitment and media sites, along with copywriting, video, WordPress implementation, SEO infrastructure, AIO/LLMO measures, page-speed optimisation, structured data, initial security, accessibility and multilingual support. Ongoing marketing support includes SEO, MEO, AIO/LLMO, content marketing, internet advertising, SNS operation, site maintenance, access-analytics reporting, security measures and WordPress recovery from tampering. The company also offers an AI customer-service chatbot built on OpenAI's API using RAG, with proprietary knowledge training, reporting features, avatar support and multilingual capability in 15 languages. Project work follows a defined flow from inquiry and hearing through proposal, design, build and quality-checked launch.
