### Japanese AI Startup Raises ¥300 Million to Monitor Brand Presence in AI Search

secondz digital closed a Series A funding round of ¥300 million on May 20, 2026, from JAFCO Group and Sumisho Venture Partners. The company has now raised ¥450 million total since its November 2024 seed round.

The company's product, secondz Agentsense, tracks how brands appear across major [generative AI](https://completeaitraining.com/tag/generative-ai-and-llm/) platforms including ChatGPT, Microsoft Copilot, and Google AI Mode. It monitors brand citations and references across multiple regions.

#### How the Tool Works

Agentsense uses Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) to analyze brand positioning in AI search results. The platform includes a positioning analysis framework called SCOPE and an improvement proposal agent that is currently patent-pending.

The tool generates specific recommendations for how brands can improve their visibility when AI systems reference or recommend products and services.

#### Target Market and Use Cases

secondz digital is targeting enterprise customers across B2B and B2C sectors. The company sees potential applications in e-commerce, recruitment marketing, and investor relations.

As AI agents become standard tools for customer research and decision-making, brands need visibility in these systems the way they once needed search engine rankings.

#### Where the Money Goes

secondz digital will use the funding to expand product development, hire strategy consultants and AI engineers, and build out a team of Forward Deployed Engineers (FDEs) to support customers.

The company is positioning itself around what it calls "Agent-Led Growth" - helping enterprises adapt to a shift toward [AI agents and automation](https://completeaitraining.com/tag/automation/) as primary customer touchpoints.
