About Stadium

Stadium Co., Ltd. operates as a technology-driven sales and business support firm, leveraging a combination of human expertise and artificial intelligence. Founded in August 2012 by Yasuhiro Ota, the company was established with the vision of transforming future workstyles. Mr. Ota's background includes a significant role in the launch and growth of Recruit's "HOT PEPPER" magazine, which provided him with a strong foundation in business development and management before he established Stadium.

The company's core business revolves around its Digital Solution Sales segment, offering a comprehensive sales outsourcing service named "SALES PARTNERS". This service is tailored for B2B companies with IT and SaaS products, supporting clients through the entire sales funnel, from strategy and lead generation to field sales and customer success. Revenue is generated by providing these outsourced sales and marketing functions to client companies seeking to expand their market reach.

In addition to its sales support services, Stadium has developed proprietary SaaS products. A notable product was "Interview Maker," a web-based interviewing system designed to digitize and improve the efficiency of the recruitment process, which launched as early as 2016. More recently, the company has focused on integrating AI into its offerings. A key product is "Dr.Tel," a generative AI tool that automates the monitoring and evaluation of call center conversations to enhance quality control. This dual approach of combining human-led sales outsourcing with AI-powered software tools allows Stadium to offer a hybrid solution for business growth.

A significant milestone occurred in July 2023, when Stadium became a wholly-owned subsidiary of ExaWizards, Inc., a company listed on the Tokyo Stock Exchange Growth Market. This acquisition integrated Stadium's sales professionals and operational expertise with ExaWizards' advanced AI technology, aiming to accelerate the market penetration of AI-driven business solutions. Following the acquisition, the leadership structure was updated, with Satoshi Ishino appointed as the new Representative Director & CEO.
