Shirofune, Inc. (Headquarters: Chuo-ku, Tokyo, CEO: Mitsunaga Kikuchi) is pleased to announce that its AI creative improvement tool 'I'm Creative' has surpassed 100,000 AI-generated creative improvements in the approximately 10 months since the feature was implemented at the end of May 2025. This feature uses AI to identify the success and failure factors of creatives based on ad delivery data and automatically generates improvement proposals.
'I'm Creative' is a product that can identify the expressive elements creating differences in performance based on ad operation data and delivered creatives (static images and videos), materializing concrete improvement proposals to try next.
It analyzes multiple creatives simultaneously and extracts the characteristics of expressive elements and story structures that cause differences in performance metrics such as acquisition numbers and conversion rates. It verbalizes the factors that caused the performance gap based on these characteristics and outputs improvement proposals not just as text, but as images incorporated into draft layouts.
## Development Background: The Center of Optimization Shifts to Creatives
As the automation of ad delivery advances, the biggest variable affecting the performance of digital advertising is increasingly converging on the creative itself. Within limited resources, it is required to continuously iterate the improvement cycle at high speed while maintaining high standards for both the quantity and quality of creatives.
'I'm Creative' is a product developed to respond to this challenge. By combining the advertising operation knowledge and data accumulated by Shirofune with AI, the accuracy and speed of the creative PDCA cycle can be improved, enabling the production of winning creatives with high reproducibility.
## Usage Track Record
'I'm Creative' was officially released in November 2024, and the function to output creative improvement drafts and layout drafts was implemented at the end of May 2025. Since then, the cumulative number of creatives analyzed by users has exceeded 300,000, and the number of improvement draft and layout image outputs reached 100,000 as of the end of March 2026.
The number of advertisers and ad agencies utilizing the tool is steadily increasing, showing clear results in visualizing operation status and streamlining improvement tasks. Among them are advertisers who have improved their CPA by 40% and ad agencies that have acquired 5 times their previous advertising budgets on the back of improved performance.
## Future Outlook
Moving forward, based on the current analysis and improvement functions, 'I'm Creative' will evolve stepwise into an Agent-type service.
In the Agent service, not only delivery results and analysis reports, but also document information such as brief materials, brand guidelines, and past reasons for adoption/rejection will be accumulated as knowledge assets for each project. The AI will cross-reference these to propose the next actions to try, along with evidence. Because the person in charge's decisions and delivery results are returned as feedback, the accuracy of analysis and execution increases the more it is used, turning team-specific know-how into a reproducible asset.
Shirofune will continue to provide support through 'I'm Creative' to enhance the reproducibility and speed of creative improvements for all companies seeking to leverage digital advertising for their own growth.
