Toss partners with Poseidon to launch AI data economy in Korea

Toss, the mobile financial platform operated by Viva Republica, partnered with Poseidon to launch a new AI data economy in Korea, bringing contribution and payment to roughly 30 million Toss users. The aim is to supply first-person training data that frontier AI models increasingly need, especially data that is hard to source on the open web. Under the partnership, Poseidon’s contributor app, Numo, is integrated inside the Toss app. Toss users can help build Korean-language datasets across voice, image, and video, and receive payment tied directly to the contributions. Poseidon says it tracks each contribution and its value through its AI data network, DATA. DATA issues a verifiable provenance trail via Trace, allowing buyers to audit where each training record came from and contributors to confirm it was counted and paid. The DATA Foundation (rebranded from Story) also supports integration partners including the human data marketplace Kled, with Poseidon described as one of the largest refined data sources flowing into the network. Poseidon highlights that Numo captures first-person data recorded by real people in real environments, positioning it as valuable “physical intelligence” raw material for robotics and autonomous vehicles. Toss and Poseidon plan to prove the model in Korea first, then expand globally. Company executives framed the move as a transparent way to compensate people whose data improves AI models, while meeting rising demand from global AI labs for high-quality, licensed, IP-safe datasets.
