Thinca

Thinca Co., Ltd. is a Japanese technology company that develops and operates the "Kaikura" communication platform. The service is designed to centralize and manage customer interactions across various channels, including phone calls, email, SMS, and video calls. Kaikura automatically records and organizes communication history for each client, making past interactions easily accessible to any team member, which helps improve service quality and operational efficiency.

The company was founded in January 2014 by Takahiro Ejiri, who serves as the President & CEO. Before establishing Thinca, Ejiri worked as an engineer at the Japan Research Institute and later as a cloud business consultant at Funai Sōken, experiences that shaped his vision for the company. His goal was to leverage IT to solve common business communication problems, such as "he said, she said" disputes, by creating a shareable, unified record of interactions. Thinca launched its core service, Kaikura, in August 2014. The company was listed on the Tokyo Stock Exchange Growth Market in March 2024.

Thinca operates on a subscription-based business model, providing its cloud platform to a wide range of clients, from local retail stores to large enterprises. By January 2025, the platform had been adopted by over 2,700 companies across more than 5,600 locations. In addition to its main platform, the company launched "Kaikura Phone," a cloud-based phone service, in January 2025 to further expand its offerings. Thinca also runs "Kaikura.mag," an online media outlet that shares insights on communication technology and business efficiency.
