Who's behind this

Built by a seller, not a middleman.

Groundwork Sourcing is built by Sang (Lee Sang-seop), a nine-year e-commerce seller who got tired of sourcing agents that only translate messages and never own the quality.

The agent I wished I had, as a seller.

Nine years selling online taught Sang the same lesson every time: agents relay a message and take a fee, then disappear the moment something goes wrong — wrong color, thinner fabric, a slipped lead time, no one accountable.

So he built the agent he wanted as a seller — on the ground, controlling the line, answering for what actually ships.
