PostData Inc., operating under the brand Qask, is a Tokyo-based AI optimization platform founded in January 2026 by Takanori Sakamoto, a former digital marketing strategist at Hakuhodo DY Media Partners and Accenture Interactive. The company focuses on helping brands monitor and optimize their visibility across generative AI search engines like ChatGPT, Gemini, and Google AI Overview. Qask's platform tracks brand mentions, citation sources, and sentiment analysis in AI-generated responses, providing actionable insights to improve digital presence.
The company targets mid-market and enterprise clients in Japan, particularly in sectors where brand reputation directly impacts revenue, such as e-commerce, financial services, and consumer goods. While financials remain undisclosed, the March 2026 launch of Qask positions PostData in the emerging AI search optimization space, competing with traditional SEO tools by addressing the opaque nature of AI-generated content. The platform's differentiation lies in its real-time monitoring of multiple AI models and prioritization engine for improvement actions. Early adoption appears concentrated among Japanese brands navigating the shift from traditional search to AI-powered discovery, though the company has not disclosed client metrics or revenue figures.
