Ecumenopolis, a Waseda University startup founded in 2022 by CEO Yoichi Matsuyama, develops conversational AI agents for diagnostic assessment. Its first product, LANGX Speaking, evaluates English conversation ability using the CEFR framework and is already used by universities, municipalities, and companies. The company runs two business lines: direct application sales and OEM platform licensing.
Ecumenopolis, founded in 2022 by Waseda University researcher Yoichi Matsuyama, builds conversational AI agents that diagnose human ability through dialogue. The company's first product, LANGX Speaking, evaluates English conversation skills against the CEFR scale and has been adopted by universities, local governments, and companies.
Waseda University was the first adopter. Since the 2023 academic year, it has used the service to assess about 10,000 students annually and assign them to English conversation classes. The university previously relied on a written test that measured listening, vocabulary, and grammar, which often placed students in mismatched levels.
Ecumenopolis operates two business lines: LANGX, which sells its own diagnostic application, and an AI platform business that licenses the technology to partners under their own brands. The platform business has recently grown to exceed LANGX in revenue.
