An algorithm designed to replicate the actions of a professional ad manager

Systematize Know-How That Produces Results

Shirofune was designed to operate like a human account manager, covering a huge number of patterns that can reproduce the thinking of a professional digital marketer.
That's why even inexperienced people can easily manage accounts while developing a stronger skillset.

Auto-bidding/budgeting

Automatically adjust daily budgets, target CPA/ROAS, and more to optimize results within your budget. We've meticulously replicated the strategies of professional ad managers for 20,000+ hours, ensuring precise budget management and maximizing outcomes. Say goodbye to the hassle of monitoring spend pacing and constantly tracking performance to allocate budgets.

Smart Recommendations

The Shirofune platform conducts daily data analysis and autonomously suggests actions, emulating the expertise of professional ad managers. These actions involve eliminating non-converting keywords and minimizing unnecessary costs to enhance efficiency.
What sets our proposals apart from typical advertising platforms is our focus not on increasing ad budgets, but on maximizing cost efficiency by suggesting exclusions and pauses for targeted deliveries. Therefore, the benefits derived from these proposals are specifically tailored for you. You can confidently approve our suggestions without any doubt, knowing that the proposed actions are designed to optimize your advertising expenditure.

Get Notified With Changes in Trends

Stay up-to-date with real-time notifications regarding changes in campaign performance and alerts for any ad stop errors, all accessible through the dashboard.

Constantly analyze and explain changes in results

We continuously analyze historical data, make comparisons, automatically identify underlying causes, and provide comprehensive explanations in plain, natural language to keep you informed.
Unlike AI approaches such as LLM, we faithfully replicate the actual ad manager's analysis process. This results in content that is highly convincing and reliable, grounded in real facts. Moreover, our outputs remain consistent in similar situations, ensuring high reproducibility. This consistency dramatically improves the efficiency of your analytical tasks.

Human Artificial Intelligence

Shirofune combines the efficiency of a state-of-the-art AI with a human-like approach to account optimization. We are the perfect extension to your in-house team so that your marketing team can focus on strategy rather than repetitive tasks.

Take Advantage of Your Lifetime ROAS

Shirofune will constantly monitor your data to understand the long term performance of each of your advertising channels. Our proprietary data attribution system allows advertisers to invest on what generates the most revenue over time rather than on short term ROAS.

We share the best case studies from real customers who have accompanied Shirofune

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.

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.

Carrot-Top - Case Study

Carrot-Top, a patriotic products retailer, struggled with rising customer acquisition costs and inefficient, agency-led ad management. Delayed reports and rigid processes led to wasted spend and missed opportunities across platforms like Google and Meta. After adopting Shirofune’s AI-powered ad automation, Carrot-Top gained real-time budget control and cross-platform optimization. Within weeks, they cut CPA by 40%, improved off-season ROAS from 2.7 to over 5.0, and replaced manual workflows with fast, data-driven decisions. Now, Carrot-Top continues to scale with Shirofune, using AI to fine-tune campaigns and prioritize high-value customers.
