About WACUL

WACUL is a Japanese technology company providing marketing DX solutions. It was founded on September 27, 2010, by Ryohei Obuchi and Hirofumi Otsu. Obuchi, the current President and CEO, formerly worked at Boston Consulting Group on new business development and management strategy. Co-founder Otsu came from beBit, where he consulted for over 100 companies in the digital space before establishing WACUL.

The company's core offering is the "AI Analyst," a SaaS tool that automates website analysis and proposes data-driven improvements. Officially released in April 2015, the platform connects with access analysis tools like Google Analytics to automatically analyze website data, identify issues such as high bounce rates, and suggest specific actions to improve conversion rates (CVR). The AI is built on data from over 40,000 websites and more than 12,000 case studies of successes and failures, allowing it to recommend strategies with a high probability of success. The service aims to let marketers focus on strategic tasks by automating data analysis and reporting.

WACUL operates on a business model centered on consulting fees rather than advertising margins, which it claims allows it to remain focused on client outcomes across all channels. Its services extend beyond the AI tool to include a comprehensive suite of solutions across the marketing PDCA (Plan-Do-Check-Act) cycle. This includes DX consulting for strategy and operations design, outsourcing services for executing SEO content creation and ad management, and a talent-matching platform called "Marketer Agent" that connects businesses with freelance marketing professionals. The company serves a broad range of B2B and B2C clients, with a particular strength in addressing complex customer acquisition processes.

Significant milestones for WACUL include starting a joint research project with the University of Tokyo's Matsuo Lab in 2015, listing on the Tokyo Stock Exchange Mothers market in February 2021 (and later moving to the Growth market), and becoming a wholly-owned subsidiary of TBS Holdings in July 2025.
