Gaiax Co., Ltd., headquartered in Tokyo and led by Representative Executive President Yuji Ueda, has announced a strategic investment in Omneky Inc., a San Francisco based AI advertising platform founded by CEO Hikaru Senju. The move is intended to bring the latest generative AI capabilities and data driven advertising models into Gaiax's marketing support business. Through the partnership, Gaiax aims to strengthen both domestic marketing services and global expansion support for its client companies.
Strategic focus on domain specific AI in digital marketing
Gaiax operates core businesses in social media marketing and creator ecosystem support, including its CREAVE platform. According to the company, competition in digital marketing is shifting from general purpose AI tools toward domain specific AI applications built on proprietary data. In this context, Omneky has developed an advertising foundation model that integrates creative generation, delivery, analysis, and optimization in a single workflow.
Omneky's platform and market traction
Omneky supports more than 6,000 active customers and has accumulated creative and performance data tied to over one billion dollars in advertising spend. Its platform is designed to unify the full advertising lifecycle, allowing marketers to generate, distribute, analyze, and optimize creative assets in one place. The company has also established strategic partnerships with major technology leaders such as SoftBank, Nvidia, OpenAI, Meta, Google, Anthropic, AWS, and SpaceXAI.
High profile backing and industry recognition
Omneky was featured in a keynote address by Nvidia CEO Jensen Huang at NVIDIA GTC, underscoring its visibility in the AI ecosystem. The company's investor base includes AI focused fund AIX Ventures, an early investor in Hugging Face and Perplexity, as well as ad tech specialist Aperiam Ventures. Additional backers include Gokul Rajaram, a director at Coinbase, Pinterest, and Trade Desk, and John Donovan, former CEO of AT&T Communications and current director at several major firms.
Commitment to the Japanese market
Omneky has focused on Japan since its earliest days and has already deployed its platform with leading Japanese enterprises, including Mitsubishi UFJ NICOS. The company says its local commitment is designed to help Japanese brands scale internationally through AI driven creative operations. Gaiax sees this as an important foundation for supporting overseas demand and advancing marketing transformation among its clients.
Executive perspectives on the partnership
Omneky founder and CEO Hikaru Senju said he was pleased to receive the investment and emphasized that Omneky has focused on Japan since its founding. He added that collaboration with Gaiax, which has deep expertise in social media operations and creator ecosystems, will accelerate the evolution of its advertising foundation model. Senju expressed confidence that the partnership will strengthen both marketing sophistication and global expansion for Japanese companies.
Gaiax Executive Officer and CREAVE President Mana Nakamura said the Omneky platform is expected to become a powerful tool for advancing AI implementation across Gaiax's marketing support operations. She noted that the group will leverage its knowledge in social media support and creative services to maximize the value of the alliance. Outside Director Kurosaki added that combining Gaiax's know-how and its community of 350,000 creators with Omneky's unified AI creative platform enables a new era of social advertising strategy.
Outlook for AI driven marketing
Gaiax views the investment as a medium to long term driver of corporate value. By integrating Omneky's advertising foundation model into group operations, the company aims to enhance AI implementation across its marketing services while helping Japanese businesses capture global demand. The partnership also reflects a broader industry move toward specialized AI models that leverage proprietary creative and performance data.
The investment marks another step in Gaiax's effort to remain competitive in the rapidly evolving digital marketing landscape. By aligning with Omneky's data rich platform and global network, Gaiax hopes to provide clients with more efficient and measurable advertising workflows. Both companies expect the relationship to expand AI adoption in Japan and create new opportunities for cross border growth.
