## Accomplishment with 1 Employee: Testify Co., Ltd. Achieves 3 Consecutive Years of 'Google Ads Premier Partner' Certification in the AI Era
**—CEO Daizo Negishi discusses the optimal solution for high-precision digital ad operations with minimal staff in the AI era—**
Testify Co., Ltd. (Headquarters: Minato-ku, Tokyo; CEO: Daizo Negishi; hereinafter 'the Company'), a strategic consulting firm for digital marketing, has been certified as a 'Google Ads 2026 Premier Partner.' This is the highest rank in the Google Partners program, awarded only to the top 3% of agencies in Japan. With this achievement, the Company has been selected for three consecutive years since the current certification system began in 2024.
How does an organization with only one employee plus minimal support maintain top-tier performance alongside major advertising agencies? CEO Daizo Negishi shares insights on the fusion of 'human expertise' and 'technology' and essential advertising strategies in the AI era.
### ■ What is a Google Ads Premier Partner?
It is the highest tier of the Google Partners program, a title awarded only to the top 3% of participating agencies in each country. To be certified, companies must meet rigorous requirements set by Google, including 'existing client growth,' 'new client acquisition,' and 'number of Google certifications,' and demonstrate results that are superior to their peers.
### ■ The Strengths of 'Testify' and its Elite Model
Common challenges in general advertising agencies include quality degradation due to one person managing dozens of accounts and slow decision-making in large teams. Testify maintains a '1-person + alpha' structure where the CEO directly oversees all projects, achieving performance that surpasses large agencies through the following strengths:
1. **Design Capability to Maximize AI Potential**
Instead of simply using Google's automated bidding or AI-generated assets, the Company focuses on strategic design that allows the AI to learn 'correct data' aligned with the essence of the business.
2. **Thorough CEO Perspective (LTV-Focused)**
Moving beyond simple ad operation outsourcing, the Company supports business growth calculated from the client's profit goals, building continuous partnerships lasting over three years.
3. **Ultra-Fast Implementation of Latest Products**
The Company is an early adopter of the latest advertising products, such as Performance Max (P-MAX) and conversion value maximization, consistently recording high ROAS (Return on Ad Spend).
### ■ Comment from CEO Daizo Negishi
'I am extremely honored to be recognized as a Premier Partner for the third consecutive year. With the evolution of AI, advertising operations have shifted from "configuration tasks" to "business design." As our company name "Testify" suggests, our mission is to continue proving the business value of our clients through digital marketing. We will continue to provide value that exceeds expectations with the speed and precision only possible in a lean organization, through strong collaboration with Google.'
