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 Lottnest Inc., which provides advertising agency and marketing support services specializing in the beauty sector (hair-removal salons and the like).

About the Company

Lottnest Inc. is a company providing advertising agency and marketing support services, with 25 employees. Handling ad operations for multiple clients—primarily DtoC brands—it has a business built on running fast creative PDCA cycles. With no dedicated in-house designer, account managers double as producers while also commissioning contractors, mass-producing 300 creatives per month (of which 150 are static images).

Background to the Adoption

Amid an industry-wide trend of "creatives growing ever more important" in ad operations, Lottnest continually needed to produce five or more new banners per week. But because everything was handled by contractors, not only did outsourcing costs mount, but every minor revision (text swaps, image changes) and resize triggered a cycle of ordering, back-and-forth, and waiting for delivery—raising the risk of falling behind competitors on speed.

While considering in-housing, the company encountered ENSOR and concluded that its ability to "instantly resize and swap content from an imported existing banner" and its "preset features usable even by non-designers" directly addressed their front-line challenges. The decision to adopt was led by Mr. Matsuoka, who heads the launch of the creative division.

Challenges Before Adoption

• Dependence on outsourcing pushed production costs far beyond the fixed monthly budget.
• Every minor revision or resize required contacting and confirming with contractors, making same-day turnaround impossible.
• With no in-house designer, there was no system for a single non-designer staffer to handle production alone.
• Having to enter prompts from scratch was a barrier, and attempts to adopt general-purpose AI tools had failed to take hold.

Why They Chose ENSOR

The biggest deciding factor was the design philosophy that "even non-designers can use it from day one." With other AI tools, users were forced to start from a blank slate using text prompts, and staff without design knowledge kept giving up partway through. Because ENSOR imports an existing banner as-is and completes resizing, text changes, and image swaps with a single click, its ability to deliver quick wins was highly valued within the company.

In addition, support for building "Skills" tailored to each client's brand and service information—creating an environment where staff can generate consistently high-quality banners simply by selecting and clicking—contributed to a smooth decision.

Expectations and Goals After Adoption

With ENSOR, the company aims to bring 20–30% of its current static-image production (150 per month) in-house via ENSOR in the first month, and more than 50% within three months. The estimated cost-reduction impact, in outsourcing-cost terms, is more than 2.4 million yen per year. Once a system is in place to mass-produce creatives within a fixed cost of 100,000 yen per month, the company expects to fundamentally improve its cost structure while maintaining production speed and volume.

Comment from the Team

"Using ENSOR, we want to build a structure that delivers results as a creative division." (Eishi Matsuoka, Creative Division, Lottnest Inc.)
