NovaSphere: A Game Changer in AI Marketing
In a groundbreaking move, Hoshigumi Corporation, based in Shibuya, Tokyo, has unveiled a major upgrade to its AI marketing agent, NovaSphere. Set to transform the landscape of digital advertising, NovaSphere now includes a state-of-the-art
Persona Agent and the capacity to generate articles, videos, and images seamlessly, all at an exceptionally low monthly fee of
98,000 yen (including tax).
Addressing Industry Challenges
Recent trends in the web advertising market highlight significant challenges: escalating competition has led to rising costs per acquisition (CPA), while the lifespan of creative content continues to diminish. In response to these issues, NovaSphere aims to alleviate both the
resource shortage and the resulting
performance instability that many marketers face today. By integrating insights from over
50 billion yen in ad spend, NovaSphere empowers marketing teams to produce effective campaigns without the trivial burdens of traditional methods.
Key Features of the Upgrade
1. The World’s First Tri-Fold Persona Agent
Unlike conventional AI systems that rely heavily on historical data, NovaSphere's new engine integrates three essential elements in real-time:
- - Big Data Analysis: Comprehensive insights on market trends and competition.
- - Academic Insights: Utilizing psychology and behavioral economics to understand consumer buying intentions.
- - Real-Time Information: Capturing current news and social media trends.
This powerful combination allows marketers to develop high-precision strategies that resonate with human behavior rather than producing generic content.
2. Complete AI-Powered Creative Production
The upgrade now allows for a one-stop solution for the entire creative production process, encompassing:
- - Article Landing Pages (LPs): From outline to draft (Implementation of CD/CI in Version 1.0).
- - Text/Image Creatives: Effective banners and catchphrases tailored to each advertising medium.
- - Video Scripts: Custom scripts designed specifically for platforms like Meta, YouTube, and TikTok.
3. Unprecedented Affordability
Responding to feedback from small businesses and startups that often find high-function AI tools financially prohibitive, NovaSphere has restructured its pricing model. Now at
98,000 yen per month—significantly less than the cost of hiring an entry-level marketer—users gain access to a 24/7 superior marketing team that operates continuously.
4. Opening the Doors for Advertising Agencies
In response to numerous requests, NovaSphere is now available for advertising agencies, enhancing client service efficiency. Additionally, clients receive unlimited access to technical support from seasoned professionals with experience managing over 300 marketing projects and
50 billion yen in campaign budgets, offering strategic consultation beyond mere tool usage.
5. Comprehensive Support for Hundreds of Industry Sectors
NovaSphere's system upgrade encompasses a broad array of industries—including eCommerce, finance, beauty, recruitment, and real estate—affording marketers an opportunity to execute persona design and creative strategies across hundreds of business types, all targeted to enhance cost-effectiveness and campaign performance.
Insights from Leadership
Natsuhiko Nobuyoshi, CEO of Hoshigumi Corporation stated, "Marketing should be a creative and joyful pursuit, yet many marketers are bogged down by mundane tasks and number crunching. The new features and pricing of NovaSphere are designed to liberate marketers from these repetitive duties, enabling them to focus on creating genuine value. Through the knowledge gained from my experiences managing over
50 billion yen, I aim to enhance the competitiveness of Japanese companies through AI and Quality Assurance support."
