Recap of our performance

40% Reduction in CPA

Carrot-Top reduced its customer acquisition cost by 40% within weeks of implementing Shirofune. The platform’s automation enabled immediate budget reallocation and performance-based optimization, eliminating the delays caused by agency reporting cycles.

Off-Season ROAS Nearly Doubled

Carrot-Top improved off-season ROAS from 2.7 to over 5.0 by using Shirofune to dynamically shift budgets across platforms and prioritize high-performing campaigns in real time, even during lower-demand periods.

Challenge

Carrot-Top, a trusted brand with decades of experience in patriotic products, faced rising customer acquisition costs and growing inefficiencies in digital ad management.

Relying heavily on external agencies, the company struggled with delayed performance insights and rigid budget processes. These delays led to missed optimization opportunities and wasted spend across key platforms like Google, Meta, and Amazon.

Managing multiple ad channels in silos also created fragmented data and limited visibility, making real-time decision-making nearly impossible—especially during seasonal sales surges when timing is critical.

Approach

To address ongoing inefficiencies and rising ad costs, Carrot-Top adopted Shirofune, an AI-powered advertising automation platform.

The team was drawn to Shirofune’s ability to unify multiple ad platforms, automate budget allocation, and deliver real-time performance insights. A 90-day trial alongside existing agency efforts provided clear comparisons.

With Shirofune, Carrot-Top eliminated delays in decision-making, enabling instant budget shifts and performance-based adjustments across both B2B and B2C campaigns. The tool’s intuitive setup and real-time dashboard helped the team transition from reactive to proactive ad management.

Results

With Shirofune in place, Carrot-Top reduced customer acquisition cost by 40% and more than doubled off-season ROAS from 2.7 to over 5.0—within just a few weeks.

Automated budget management and real-time campaign optimization enabled the team to eliminate wasted spend and respond quickly to performance trends across platforms.

By shifting away from delayed agency reporting to live dashboards and AI-driven automation, Carrot-Top significantly improved ad efficiency, ensuring every dollar spent delivered stronger, measurable results.

Direct Agents - Case Study

Direct Agents, a U.S.-based digital marketing agency, faced challenges with manual ad management tasks, especially with Amazon Ads, limiting their ability to focus on strategic initiatives. After integrating Shirofune’s automation, they reduced ad management time by up to 63%, freeing up resources for high-value tasks like audience segmentation and creative testing. The E-Commerce team saw a significant drop in workload from 125 hours to 45.8 hours per account. This automation led to impressive results, including a 75% increase in MQLs with only a 14% rise in ad spend. Direct Agents continues to expand Shirofune’s use across platforms, optimizing omni-channel marketing and driving long-term client success.

Zilker Partners - Case Study

Zilker Partners, a U.S.-based digital marketing agency, struggled to scale operations after shifting to a generalist model, with staff handling multiple tasks across paid media, SEO, and content. The lack of an integrated platform for real-time optimizations limited campaign effectiveness. By adopting Shirofune, they streamlined campaign management across platforms, enabling generalists to manage ad operations independently. In just one month, they onboarded 24 client accounts and doubled the account capacity per manager from 6 to 12. Automation saved up to 54 hours per month per manager. Zilker Partners now efficiently scales operations, allowing generalists to focus on strategic initiatives while managing high-performing campaigns across platforms.

Yamazen - Case Study

Yamazen implemented Shirofune to improve the efficiency of its Amazon ads for over 10,000 products. Facing challenges with limited resources and a complex ad management interface, Yamazen leveraged Shirofune's automation for bid adjustments and budget management. Within two months, ad-driven sales increased by 1.3 times, and ROAS improved by 18%. Daily reports from Shirofune enabled quick responses to demand changes, resulting in a streamlined and data-driven approach to campaign optimization, significantly enhancing Yamazen's advertising performance on Amazon.
