Toss Brings 30 Million Users Into the AI Data Economy in Partnership With Poseidon
On June 26th, 2026, in Palo Alto, United States, a groundbreaking partnership was announced between Poseidon, the data infrastructure platform, and Toss, the popular mobile financial platform operated by Viva Republica. This collaboration marks Toss’s entry into the realm of AI data and opens up new opportunities for its 30 million users to contribute to AI training and get paid for their valuable input.
In a world where frontier AI models are in need of real-world data for training, Poseidon is leading the way in sourcing and licensing such data. Traditional web scraping methods have limitations when it comes to capturing how people truly interact in the physical world. Through their partnership, Poseidon and Toss aim to address this gap by allowing users to contribute real-world data across various modalities such as voice, image, and video.
The collaboration introduces Poseidon’s contributor app, Numo, within the Toss platform. Users can now actively participate in building Korean-language training data and receive direct payment for their contributions. Numo tracks each contribution and its value, while Toss facilitates the financial aspect, ensuring that users are fairly compensated for their data contributions.
Every contribution made through Numo is registered on the DATA network, which offers a verifiable provenance trail through its public audit layer, Trace. This transparency allows both buyers and contributors to track the origin of training data and ensure fair compensation. The DATA Foundation, formerly known as Story, is actively involved in refining data sources, with Poseidon being a key contributor to the network.
Numo focuses on collecting first-person data, which is crucial for developing physical intelligence in AI applications such as robotics and autonomous vehicles. The demand for such data is on the rise globally, and Korea, with its rich real-life data and Toss’s user base, is poised to supply this valuable resource. The partnership plans to validate the model in Korea before expanding to other markets worldwide.
Changhoon Seo, Executive Director of New Business at Toss, emphasized the importance of high-quality data in the growing AI industry. Toss aims to create a user-friendly environment where individuals can actively participate in the data economy and be rewarded transparently for their contributions.
SY Lee, Chief Strategy Officer and Chairman of Poseidon, highlighted Korea’s strategic position in AI data, financial infrastructure, and mobile experience. He expressed confidence in Toss as the ideal partner to pioneer user-contributed AI data and set a standard for global adoption.
In conclusion, Poseidon’s innovative approach to sourcing real-world data for AI training, coupled with Toss’s expansive user base and financial expertise, signals a new era in AI data contributions. The collaboration sets a precedent for empowering users to actively participate in the data economy and be fairly compensated for their valuable input.
