AMSTERDAM, December 1st, 2025 – alpha.one, a leader in AI-driven pre-testing for advertising, today announced the full release of junbi's Sendō. Powered by Google’s Gemini models, Sendō is an advanced agentic AI system designed to solve the "last mile" problem in ad testing: moving from analyzing data to taking action.

While traditional ad testing platforms excel at diagnosis—showing heatmaps of where attention drops—marketers are often left asking, "Now what?" Sendō answers that question. It rejects the passive "co-pilot" interface common in the industry in favor of an active "Guide" (Japanese: Sendō) persona that prescribes tangible next steps to optimize creative work.

Bridging the Gap Between Data and Creative

“Our metrics have always been perfect at showing you exactly where an ad breaks down—the precise second attention drops. But a graph doesn't tell you how to fix it,” said Daan van der Wiele, Co-Founder & CPO at junbi.ai. “That left creative teams identifying the problem but getting stuck on the solution. We built Sendō to close that gap. It doesn't just hand you a score; it synthesizes the 'what' and the 'why' to deliver expert recommendations. It moves us from diagnosing the patient to prescribing the cure.”

Powered by Agentic Architecture

Sendō represents a shift from simple chatbots to complex agentic workflows. Where the beta version had access to a single custom model, the new agentic setup uses multiple. By leveraging the speed and multimodal capabilities of Gemini, junbi.ai has built a system where four specialized agents collaborate to answer a single user query:

• The Video Researcher: Visually decodes the creative to understand the narrative flow and context.
• The Data Researcher: Interprets junbi’s proprietary performance metrics and attention heatmaps.
• The Knowledge Base Researcher: Validates insights against a vast library of neuroscientific research and benchmarks.
• The Synthesizer: Unifies these perspectives to deliver a single, strategic recommendation.

From Preparation to Guidance

The release cements the platform's dual-structure philosophy: junbi (Preparation) provides the rigorous testing environment, while Sendō (Guidance) provides the intelligence to navigate it.

“In today's media landscape, the gap between a good ad and a great one is measured in millions,” said Coen Olde Olthof, Founder & CEO. “Sendō transforms junbi from an analysis platform into an accelerated optimization engine. For our clients, this means no more guesswork. It means faster time-to-market, higher-performing creative, and a direct, measurable impact on campaign ROI. We're not just providing data; we're providing the active leadership to ensure our clients win.”

Sendō is available immediately to all junbi users directly from their prediction pages. For more information on how Sendō works, visit our knowledge base.
