Aiming to break free from dependence on contract designers and build a production system of around 100 creatives per month while accelerating the PDCA cycle. REHATCH Inc. (headquartered in Chiyoda-ku, Tokyo; Representative Director: Ryota Sakoda) is pleased to announce that its marketing AI OS "ENSOR" has been adopted by Dr. Training Inc., which operates more than 40 studios in the personal training and fitness industry.

About the Company

Dr. Training Inc., founded in October 2014, is a company in the personal training and fitness field. Based in Ebisu, Tokyo, its core business is the management and operation of sports and health-promotion facilities, with 150 employees (as of April 2024) and revenue on the order of 1 billion yen. It operates personal gyms tailored to each individual's goals and began using ENSOR in April 2026.

Background to the Adoption

The company's marketing lead, Mr. Higashida, faced challenges in producing ad creatives. Running a fast PDCA cycle requires a large number of creatives, but production was handled by an external contract designer. Costs kept mounting, while a ceiling of roughly 5–10 creatives per month remained. Driven by a strong desire to "build a production system two to three times the current volume," he was exploring AI-based solutions when he encountered ENSOR through a seminar.

Challenges Before Adoption

• The cost of commissioning contract designers was high, capping production at around 20 creatives per month.
• There were not enough creatives to run the PDCA cycle, so the pace of ad improvement could not increase.
• The company aimed to bring creative production in-house, but its internal structure had not kept pace.

Why They Chose ENSOR

The quality of the creatives shown in the sales demo was the deciding factor for adoption. The tangible sense that they could "mass-produce while ensuring quality," together with a vision of accelerating the PDCA cycle by building a mass-production system that directly addressed their front-line challenges, helped secure internal approval. Another point they valued was the expectation of an operational design that lets teams run independently even without high AI literacy.

Expectations and Goals After Adoption

With ENSOR, the company aims to build a creative mass-production system of around 100 pieces per month. Through a clear division of roles—"heavy design work (interiors, exteriors, signage) to contract designers, and day-to-day creatives that drive the PDCA cycle to ENSOR"—it seeks to optimize outsourcing costs and establish an in-house marketing structure. As the AI accumulates knowledge specific to Dr. Training, the company also envisions building a "dedicated AI foundation" that grows more accurate the more it is used.
